Hello Teams!
I have posted the new JK rules for OSRC below. I would appreciate comments from JK owners and all teams for any rule revisons for 2013.
6. JK Class (license and registration required)
1.1 Tires-Maximum tire size is 37", based on manufactures sidewall stamp. Three bonus points (-3) issued for each inch below 37" to a minimum of 33".
1.2 Steering-JK class is limited to hydraulic assist of stock type components (hydraulic rams OK). Rear steer or full hydraulic steering is not allowed. Cross over steering acceptable.
1.3 Frame
1.3a Frames must be OEM, or direct OEM design aftermarket replacement. Frame re-enforcement allowed.
1.3b Frame rail modifications are not allowed, including cutting holes in the frame rails for custom brackets (except as allowed in 1.7 below). All bolt on or weld on custom brackets are permitted.
1.3c Frames cannot be drilled or punched to lighten them.
1.4 Body
1.4a Bodies must be full width of OEM. Bodywork must extend a minimum of 24" past the center of the rear axle. Some trimming of body allowed such as fenders and corner panels. Fenders may be trimmed under the area that would be covered by a factory or aftermarket fender flair or a maximum of 3”.
1.4b Front fender wells may be omitted. All flooring and fire walls must be fully intact with the exception of the following:
1. The hump area directly over the transmission and transfer case which may be modified to accommodate aftermarket products or lifting of stock components.
2. The floorboard may be cut or modified for clearance of rear shocks, fuel tanks and routing of fuel lines.
1.5 Radiator-Radiators must be in factory position and covered by the hood.
1.6 Seating-Vehicles must have two (2) seats side by side.
1.7 Suspension
1.7a Stock configuration suspension designs required. Air shocks or coil over systems are allowed with a 10 point penalty (+10).
1.7b No limitation on suspension attachment point measurements, but overall wheelbase MUST remain +- 3 inches of stock.
1.7c Manual or automatically controlled suspension systems that compensate ride height are not allowed. Front bumper mounted winches may be used as an adjustable limiting strap for the front axle. Rear axle winches are also allowed as an adjustable limiting strap.
1.7d Portal Axles are not allowed.
1.8 Fuel System-Factory fuel tank and vents are acceptable. The tanks and vents must be in the stock location and configuration to pass tech. Any modifications to the factory systems will require a rollover valve and fuel vent line shutoff valve located near the fuel tank and accessible to track personnel.
1.9 Factory ignition switches (kill switches) are acceptable for the JK class if in the original factory location and configuration.
