Hi Teams,
Brian Cannon and I have discussed what the teams have stated regarding the stock class and the frame rules. We would like your comments regarding the following revision for the stock class rules (changes are in red on the attached PDF View attachment Stock Class Revisions.pdf) :
1. Street Stock 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 - Street Stock 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 (box type rectangular or square tubing only). Frame reinforcement allowed.
1.3b Frame rail modifications are not allowed as follows: cutting holes in the frame rails for custom brackets as allowed in 1.7 below, notches in frames for suspension as allowed in 1.7 below, bolt on or weld on custom brackets, and frame adjustments to maintain stock wheel base +- 3” 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. Full recognizable 4x4 bodies i.e. Jeep, Toyota, Ford, Chevrolet, I.H. etc., are required. 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:
1.4b1 The hump area directly over the transmission and transfer case may be modified to accommodate aftermarket products or lifting of stock components.
1.4b2 The floorboard may be cut or modified for clearance of rear shocks, fuel tanks and routing of fuel lines.
1.4c Flat beds allowed on trucks with a +20 point penalty assessed.
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. Example: leaf from factory, leaf for competition, coil/leaf from factory, coil/leaf for competition, etc... Double shackle, 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 for the vehicle body.
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 Shackle reversal approved for leaf springs. Shackle hangers may use holes cut in the frame for leaf spring shackle bushings. Rear leaf springs mounted inside the frame are allowed (frenched).
1.7e Portal Axles are not allowed.
