1.0 DEFINITION

Jeepspeed Challenge Class 1700.
The Jeepspeed Challenge is for short wheel base Jeeps with 6 Cylinder and 4 cylinder engines,
excluding Pentastar DOHC engines which must run Jeepspeed Class 2700. Vehicles must be stock
wheel base +/- 2″ not to exceed 110.5″. (Grand Cherokee WK 108.5, +/- 2″) Short w.b. Comanche
pickups will be permitted at stock wheelbase +/- 1″ but rear wheel travel will be restricted to 10″.Two door Wrangler JK models will be restricted to the 3.8 OHV engine
Any option combination (2-door, 4-door, 2-wheel-drive, 4-wheel-drive, 4-cylinder, V6, inline 6, manual transmission, automatic transmission, etc.) is acceptable, as long as it was available from the
manufacturer in that configuration. Jeeps with independent front suspension must use original model 6- cylinder engine, original transmission and original transfer case as supplied by the manufacturer.
Wheelbase will be measured at stationery ride height.
All Vehicles must conform to race sanctioning body’s rules. Smog equipment may be removed for competition, unless required by the event organizer. Highway registration and insurance may be required
for rally events. Any Jeepspeed rule can be changed without notice at the sole discretion of Jeepspeed.
Every effort will be made to give due notice.
Major components, such as suspension kits, must be readily available to the general public through our approved supplier list. Unless a modification is allowed or component listed as open herein, that part must remain original. Any component or assembly can be strengthened by adding material, but the original must remain intact. Chasiss and suspension components may be replaced or substituted as described in these rules. No expressed or implied warranty of safety shall result from publication of these rules. They are intended as a guide for the Jeepspeed Class 1700 and in no way guarantee against injury or death to participants, spectators, team members or others. The driver of record is responsible for the race worthiness and safety of the vehicle.

2.0 Sanctioning Body Regulations
Jeepspeed rules do not in any way replace or modify the competition and safety regulations issued by the race organizer or sanctioning body. Stock or Production class rules will apply in Jeepspeed Class 1700
unless modifications are specifically allowed herein. This does not necessarily mean that any organizer
will allow you to run in the Stock or Production classes (in the event that they do not have a Jeepspeed
specific class), but you will still be held to the rules for those classes. Starting order will be selected by the race organizer. Jeepspeed is not responsible for the safety and mechanical condition of any race vehicle. Prior to competing in any given season teams can designate a Driver of Record and a Secondary Driver. Driver of Record is responsible to ensure all team members sign all waivers and releases before the event. Driver of Record or the designated Secondary Driver must drive the race vehicle either off the official start or across the finish line of the event to gain Championship points, prize money or awards for the Driver of Record. The only exception is if the driver of record is injured during the race and is unable to continue during the event safely.

4.1.3.2 Axle control arm brackets may be strengthened by adding material. Axle control arm bracket bolt
centers must remain within a 2″ radius of the original mounting position relative to the axle centerline of the vehicle on which the axle is now mounted. Front beam axles can be utilized from any model that runs in
Class 1700 but must meet outside track with as in rule 4.1.1.6.
4.1.3.3 Any manufacturer suspension mass produced kits, parts and components from our approved list
of vendors may be used provided it has a part number and is readily available to the general public. Kit components must be installed per manufacturer’s instructions. Sub frames or relocation brackets are
permitted and may be welded in place after installation per manufacturer’s instructions. Suspension
brackets and components may be strengthened by adding material. Bushing, Johnny Joints, Heims may
be replaced or upgraded. Components from differing suppliers can be used on one vehicle.
Manufacturers are to contact Jeepspeed for approval.
Must use suspension kit or componnents from a Jeepspeed approved manufacturer. Companies currently approved include Currie Ent., Skyjacker, Rusty’s Off Road, Rubicon Express, Full Traction, Poly
Performance, Fabtech, T&J Performance, Jeepspeed Products, Rancho, ZONE off road, Rough Country, TrailMaster, ProComp, BDS, Rock Krawler, Nth Degree, Clayton Off Road, Teraflex, Radflo, King, Icon,
Fox, Bilstein, Synergy MFG. American Motorsports, Swayaway, Arteck. Genright.. …NOTE, other
manufacturers are encouraged to apply for approval
4.1.3.4 Maximum front wheel travel is 10″. This will be measured with the vehicle jacked up so both front tires are off the ground and the frame supported. Wheels and tires must be left in place, and limit straps must be fully extended. On beam axle models the suspension travel will be considered the vertical distance from the metal bump stop pad on the axle to the metal bump stop bracket /pad on the frame, not including the rubber, plastic or urethane bump stop. On IFS models the front wheel travel will be measured at the center line of the front spindle as the suspension is stroked through its travel from metal stop top metal stop. The length of the shock absorber shaft will not be used to calculate or measure wheel travel. Suspension travel may be checked before or after an event. Competitors are responsible at all times for providing the correct jacking devices for their jeep in the technical inspection area prior to the race as well as in the winners impound area after the race to enable race officials to check wheel travel.

4.1.3.5 Limit straps must be used on both ends of the front beam axle. They must be located in a vertical
plane toward the outside of the centerline of the frame rails. The straps must mount to the axle on or
forward of the vertical centerline of the axle, and the upper mounts must lie vertically above or forward of the lower mounts. Straps must be double layer and be manufactured by a name brand supplier. IFS limit strap
location is open but must restrict travel to 10″ and front shocks may be removed to check travel measurements 4.1.3.6 Springs are open (diameter, rate, length, etc.) but the upper spring mount must remain in the
stock location and the lower spring mount must be within 2″ of the original location. IFS models may use approved aftermarket direct bolt in coil over shocks utilizing factory upper mountings. CJ and Scrambler
specific must use front and rear leaf springs with shackles not to exceed 6″ eye to eye.
4.1.3.7. Shock rules…… A single shock absorber per side is allowed with a maximum diameter of 3″
with no form of bypass, or 2-1/2 inches with external or internal bypass or adjustment. Currently, the
largest actual outside diameter of a commercially available 2-1/2 inch shock body is 2.65 inches, and this
will be the maximum allowable measured diameter. Shocks or reservoirs with cooling fins will be
measured at the base of the cooling fin. Rate adjusters or anti cavitation adjusters may be added to
resevoirs The upper shock mount must be in the approximate stock location and must not protrude through
the inner fender well into the engine compartment (except for only the stock pin-type upper shock mount if used).

The upper shock mount may be strengthened by adding material. The lower shock mount is open, but must
mount to the axle and not the control arm on beam axle models. On IFS models the lower shock mount must
attach to lower A arm within 2″ of original position.Remote reservoirs are allowed with a maximum
diameter of 3″ and a maximum length of 16″, and may only utilize a single hose for fluid attachment to the shock
(no double-hose recirculating systems). Liquid cooling of shocks and reservoirs is not allowed. YJ Wranglers may
use TJ front suspension kits or XJ front axle/suspension conversion kit (currently approved kit from Warrior Products.). 4.1.3.8 If applicable a stock concept panhard (or track) bar system must be used. Panhard bars and brackets are open. Aftermarket or stock brackets may be strengthened by adding material.

4.1.3.9 Bump stops are required to attach in the original locations and may be of any material.
Air/Hydraulic bump stops are allowed. Mounting locations on frame may be modified only enough to allow mounting of new bump stops, but bump stop angles may be changed. WJ Grand Cherokees must install front hydraulic or air bump stops in same location as XJ, TJ and ZJ models i.e. inside the front coil, or, may use the original factory rubber bumps or aftermarket urethane bumps in the original locations. WJ models can place hydraulic bump stops inside rear springs or use the original location for rubber or urethane bumps. On IFS models the front bump stop location is open.
4.1.3.10 Original type steering box or rack and pinion must be used but may be modified and must be
mounted in stock location using the stock mounting holes; however the mounting area may be
strengthened by adding material. Steering quickener box may be added and steering shaft modified or
replaced as necessary. Steering components (tie rods, tie rod ends, pitman arm, track bars etc.) are
open. The steering system must remain stock concept OF tie rod and drag link or rack and pinion (i.e. no
remote steering, bell cranks, etc.). Power steering pump and reservoir is open, and fluid coolers and
filters may be installed. I.F.S. models must use stock rack and pinion steering.
Beam front axles must use stock concept of steering knuckles and ball joints. King pin steering is not
permitted on straight axles.
4. 1.4 Rear Suspension
4.1.4.1 Stock frame spring mounts may be strengthened by adding material or replaced but must remain
in original location.
4.1.4.1. Stock rear coil spring mounts must be retained, but may be strengthened by adding material.
Rear coil spring mounts may be relocated to accommodate wheel base changes allowed the class rules
for Wranglers.
4.1.4.2 Axle leaf spring brackets may also be strengthened by adding material, but must remain in original locations relative to axle centerline. Pinion angle may be changed from stock by rotating the spring bracket on the axle,
but the spring must remain mounted over the axle using stock mounting
method. Short wheel base Comanche trucks can use the stock spring under configuration. Short wheel
base Wrangler spring bucket may be re-located to long wheel base 103.4″ position. The frame may be
notched but upper plain of the frame may not be broken .YJ Wranglers may install TJ rear suspension
systems
4.1.4.3 Cherokee XJ , Wrangler YJ, CJ and Scrambler rear springs may be lengthened to a maximum
57.5″ measured eye to eye through the arc of the main leaf, and must mount in the original stock manner
under the frame and over the axle. Rates and capacities are open. Front spring mount may be moved forward
2.5″ from stock location. Rear shackles are open but must not exceed 6″ eye to eye. Two single point or one three-point anti wrap bars may be used on the rear axle assy.

4.1.4.3. Rear coil springs may be of any manufacturer.
4.1.4.4 Maximum rear suspension travel is 12″. This will be measured with the vehicle jacked up so that
both rear tires are off the ground and the frame supported. Wheels and tires must be left in place, and
limit straps must be fully extended. The suspension travel will be considered the vertical distance from the metal axle tube/pad to the metal bump stop mounting location/pad on the frame, not including the rubber, plastic, or urethane bump stop. Suspension travel may be checked before and after an event.
4.1.4.5 Limit straps must be used on both ends on the rear axle. They must be located in a vertical plane within 2″ either way of the center line of the frame rails. The straps must mount to the axle on or behind
the vertical centerline of the axle, and the upper mounts must lie vertically above and behind the lower mounts. Straps must be double layer and be manufactured by a name brand supplier.
4.1.4.6 A single shock absorber per side is allowed with a maximum diameter of 3″ with no bypass, or 2-
1/2 inches with internal or external bypass or adjustment. Currently, the largest actual outside diameter of a commercially available 2 1⁄2 inch shock body is 2.65 inches, and this will be the maximum allowable measured diameter. The upper shock mounts may be inside the passenger compartment, but minimal material must be removed from the fender wells or floor for installation. The lower shock mount is open but must mount to the axle directly (no remote mounted shocks). As an alternative: two shock absorbers per side are allowed with a maximum outer body diameter of 2 inches (2.15 inches actually measured body diameter), but these shocks must be mounted completely below the floor pan.

Shock location is optional, but lower mounts must attach to the axle directly (no remote mounted shocks). Remote reservoirs are allowed with a maximum diameter of 3 inches and a maximum length of 16 inches and may only utilize a single hose for fluid attachment to the shock (no double-hose recirculating systems). Liquid cooling of shocks and reservoirs is not allowed. Anti-cavitation or rate adjuster may be added to resevoirs.
4.1.4.7 Bump stops are required in the original locations and may be of any material. Air/hydraulic bump
stops are allowed. Bump stop mounting locations on frame may be modified only enough to allow
mounting of new bump stops.
4.1.4.8. Must use rear suspension components from the approved suspension manufactures. Rear track
bar may be replaced by triangulated link systems. Rear upper arm kits may be modified to fit triangulated brackets on the rear axle.
4.1.5 Engine
4.1.5.1 Restricted to original equipment engines supplied to the original Jeep model. Any year model
overhead valve or single overhead camshaft engine is allowed as long as it was originally available in that specific Jeep model. Until further notice double overhead camshaft engines must run in Class 2700

4.1.5.2 Maximum engine displacement is 4097cc (250 cu in.) This would allow a 4.0-liter engine to be rebuilt with .060 oversized pistons with a little extra for honing cleanup. Four cylinder and V6 engines may be bored and/or stroked to a maximum displacement of the same size. YJ Wranglers and CJ models that were originally sold with 4.2 liter engine will be permitted to run that engine with carburetor. If a 4.2 is converted to late model 4.0 they must use late model fuel injection.

4.1.5.3 Stock block, and stock or steel replacement cylinder head must be retained. It may be bored, honed, decked, and otherwise machined as long as all other rules are adhered to. Stock block, and oil pan must be retained. All internal parts are open. No dry sump lubrication systems, but oil pan may be modified to increase capacity. 2.8 liter V6 engines may be replaced by similar larger cubic inch GM crate motor with iron block and head castings similar to those used in Jeep XJ’s. Maximum size 250 c.i.
.4.1.5.4. Engines may be sealed after being checked in post-race tech. Any engines in the top 3 at any event may be checked or re-checked. In order to contain engine build costs Jeepspeed, at its discretion, may claim any other competitor’s engine for the sum of $4,000. This will be the long block assembly. Jeepspeed will have in available, for sale, sealed Jeepspeed long block crate race motors for $3,900. YJ Wranglers and CJ variants may use original 4.2 engine with Carb. or use later 4.0 with fuel injection.
4.1.5.5 Fuel injection intake manifold must remain original factory unit from any version of the engine installed (i.e. any XJ, TJ, ZJ, WJ intake manifold may be used on a 4.0 L motor. YJ Wranglers may use later model systems). Manifold may be port-matched. Throttle body may be replaced with any 4.0 Mopar or aftermarket unit, or the pre 2001 Jeep/Mopar 4.7 unit, all with a maximum I.D. of 62mm at its narrowest point. The approved 4.0 units are any unit designed and sold specifically for the 4.0 engine as direct bolt on throttle body that matches either the early Renix 3 bolt manifold or the later Chrysler 4 bolt manifolds. The only adaptor plates that are approved are adaptors specifically sold to install the Chrysler late model throttle body onto an early Renix intake manifold, or adaptor plate to install the pre 2001 4.7 TB to 4.0 intake manifold. Throttle body spacers that utilize the stock factory bolt pattern are permitted. Early V6 and 4-cylinder engines which came originally carbureted may use any intake manifold and single carburetor combination, or aftermarket single body fuel injection (multi-point injection not permitted). Late model Jeep factory stock multi-port injection system with 62 mm maximum throttle body internal diameteris allowed on 4cylinder models. Late model V6 engines must use stock throttle body.

4.1.5.6 Injectors may be of any size, but must fit into intake manifold without
modification. Aftermarket ECU and ignition system with a retail price below $2950 are allowed. Competitors may be asked for proof of purchase . Fuel pump(s) and filters open.
4.1.5.7 Air filters are open but may not protrude through hood, grille, or fenders. They maybe located inside the cab with a minimal entrance though the fire wall.
4.1.5.8 Exhaust may exit anywhere as long as it does not allow fumes to enter the vehicle. Any header is allowed.

4.1.3.6 Springs are open (diameter, rate, length, etc.) but the upper spring mount must remain in the
stock location and the lower spring mount must be within 2″ of the original location. IFS models may use approved aftermarket direct bolt in coil over shocks utilizing factory upper mountings. CJ and Scrambler
specific must use front and rear leaf springs with shackles not to exceed 6″ eye to eye.
4.1.3.7. Shock rules…… A single shock absorber per side is allowed with a maximum diameter of 3″
with no form of bypass, or 2-1/2 inches with external or internal bypass or adjustment. Currently, the
largest actual outside diameter of a commercially available 2-1/2 inch shock body is 2.65 inches, and this
will be the maximum allowable measured diameter. Shocks or reservoirs with cooling fins will be
measured at the base of the cooling fin. Rate adjusters or anti cavitation adjusters may be added to
resevoirs The upper shock mount must be in the approximate stock location and must not protrude through
the inner fender well into the engine compartment (except for only the stock pin-type upper shock mount if used). The upper shock mount may be strengthened by adding material. The lower shock mount is open, but must mount to the axle and not the control arm on beam axle models. On IFS models the lower shock mount must attach to lower A arm within 2″ of original position.Remote reservoirs are allowed with a maximum diameter of 3″ and a maximum length of 16″, and may only utilize a single hose for fluid attachment to the shock (no double-hose recirculating systems). Liquid cooling of shocks and reservoirs is not allowed. YJ Wranglers may use TJ front suspension kits or XJ front axle/suspension conversion kit (currently approved

kit from Warrior Products.).
4.1.3.8 If applicable a stock concept panhard (or track) bar system must be used. Panhard bars and brackets are open. Aftermarket or stock brackets may be strengthened by adding material.

4.1.1.11 Grille, headlights, tail lights, must remain stock and functional. Headlights may be replaced with non-D.O.T. lights for off-road events, but must remain relatively stock in appearance. The one-piece Hinson/Jeepspeed front grill assembly is approved for Cherokee XJ models.
4.1.1.12 Hood must be positioned in stock location, and nothing may protrude through it. Holes may be cut through the hood for increased cooling, but must not exceed a total of 36 square inches. Hood may be re-formed for additional engine bay clearance, but hood scoops and cowl induction are not permitted. Rear of hood may be lifted maximum 2″ for additional cooling.

4.1.1.13 Complete dashboard is optional. Aftermarket steering wheel with quick disconnect is allowed. It is recommended to remove steering lock from column.

4.1.1.14 The following decals must be included on the vehicle:
Series sponsors on upper and lower windshield deflectors. Series sponsor logo must be readable in photo images. Jeepspeed Banner Decals on both sides. Tire Manufacturer Decals on both sides front fenders. Wheel manufacturers decal on both rear fenders. Jeepspeed Number plate on both front doors. From time to time competitors will be required to run additional decals.

E85 and/or additives or octane boosters are not permitted or. Any gas that is colored is not legal.
4.1.6 Drive train. All Wranglers must be 4×4, and capable of being driven in 4-wheel drive at the start of
the event.
4.1.6.1 Transmissions. Restricted to factory original equipment transmissions, transfer cases, supplied
with Jeep 6-cylinder models delivered in the United States that are permitted in this race series. Any year
model components are allowed, as long as they were supplied in a 6 cyl Jeep since 1984.
4.1.6.2 Transmission may be any model offered with any Jeep 6-cylinder model since 1984, manual or automatic. Internal components may be modified, but case must remain as delivered.
NOTE ….4.1.6.2. Transmissions allowed with inline 6-cylinder engines will now include Mopar 727
Torquefight, and GM Turbo 400. These transmissions were available in 6 cyl AMC 4.2 Grand Wagoneers
and J series trucks, so bell housing bolt pattern is not a problem The rationale being more miles between rebuilds, lower cost of rebuilds, and increased reliability therefore saving money.
Vehicle must use a transmission that came with compatible block. i.e. Only late model V6 can use late
model trans.
These727 and Turbo 400 larger transmissions may require reforming the floor on some models. Any
changes must be made with the same weight and gauge material.
Clutches, torque converters, and oil coolers are open. All IFS models permitted to run in this series must
use the original transmission.
4.1.6.3 Transfer case (if used) may be any model offered with a Jeep permitted in this class. Internal
components may be modified, and low range components removed, but case must remain as delivered. Slip-yoke eliminator kit may be installed, as long as kit is readily available to the general public.
4.1.6.4 Front and rear axle assemblies are open but must retain original axle concept. Gears, differentials, and axles are open. Axle housings may be strengthened by adding material. Two-wheeldrive beam front axle assembly must remain stock tube concept but may be strengthened by adding material. Models with independent suspension may use all stock components but material may be added following the original contour of the original part, or may use Jeepspeed approved aftermarket IFS suspension kits 4.1.6.5 Brakes must be street legal components. Pads and shoes may be of any manufacture and material. Rotors may be cross-drilled and or grooved. Anti-lock fuse or relay may be removed, or anti-lock system removed altogether.
