Class 1
| Rule # | Category | Description |
|---|---|---|
| 1.01 | Body | Bodies may be constructed of any material (lexan, ABS, 3d printed, etc.). The width of the body at the doors of the cab must be wider than the inside edge of all four tires. Bottom edge of front grill and rear tailgate/trunk must be below the top edge of all four tires when the vehicle is at rest on flat ground. Bottom edge of bodies must be at a height where the transmission is not seen when viewed from the side. Front and rear of body must extend past the front edge of the front tires and rear edge of the rear tires. This may be accomplished with chassis mounted bumpers if the body itself does not meet requirements. Lexan bodies must have a front windshield and rear window. Bodies with roll cages instead of cabs (such as the Axial Deadbolt) do not need to have windshields or rear windows. |
| 1.02 | Chassis | Must use a chassis that consists of two vertical rails or bars in similar configuration as stock chassis. Rails may be carbon, aluminum, titanium, 3d printed, etc. No tube chassis or stick style chassis. Chassis must use a 0 degree skid plate. No angled skid plates. A chassis is considered to have a zero degree skid plate when the skid plate is parallel to the top edges of the front and rear shock tower portion of the chassis rails. Chassis rails must extend past the centerline of both front and rear axles. |
| 1.03 | Bumper | All vehicles must run a front bumper that is wider than the widest part of the frame rails. Bumper must extend past the front edge of the front tires and mounted in such a way that the lower edge of the bumper is no higher than the lower edge of the front of the body. Lights not required. |
| 1.04 | Motor | Brushed or brushless motors allowed. Single motors only. |
| 1.05 | Battery | Any lipo battery. Battery may be relocated but must be attached to chassis and must stay under the body. |
| 1.06 | Electronics | No electronics limitations. |
| 1.07 | Wheels | Any wheel with maximum diameter of 1.0″. One piece wheels or beadlocks allowed. |
| 1.08 | Tires | Any tire with 57mm maximum outside diameter. Tires must be constructed of a single piece of rubber as originally manufactured. Tires must retain stock markings on sidewall including brand, model, size, etc. Tire tread may be trimmed/removed. Tires may be vented. |
| 1.09 | Drivetrain | Full time 4WD only. No 6×6 or dually setups. Front wheel steering only. Vehicles with 4 wheel steering may compete in this class as long as rear steer is not used during the run. Use of rear steer will be considered a disqualification. Drivetrain limited to maximum of one front driveshaft assembly and one rear driveshaft assembly. Driveshafts must connect transmission to the axle in as straight of a line as possible. |
| 1.10 | Suspension | Aftermarket shocks allowed. Must use 4 shocks – 1 per tire. Suspension links may be changed. |
| 1.11 | Gate Width | Minimum 6.5″/165mm |

|---|---|---|
| 2.01 | Body | Any lexan or hard plastic body that resembles a full size, highway-capable vehicle. No tire coverage rule. Tube and flat beds are allowed. Bottom edge of bodies must be at a height where the transmission is not seen when viewed from the side. When viewed from above, bodies, beds, etc. must extend past the centerline of the front and rear axle and must cover motor, receiver, speed control, and battery. Lexan bodies must have a front windshield. Bodies with roll cages instead of cabs (such as the Axial Deadbolt) do not need to have windshield. |
| 2.02 | Chassis | Must use a chassis that consists of two vertical rails or bars in similar configuration as stock chassis. Rails may be carbon, aluminum, titanium, 3d printed, etc. |
