Product details
Red Dynalite calipers pair with Wilwood drilled/slotted rear rotors on Chevy 12-bolt eliminator axles. Resolve the offset and check wheel clearance. Wilwood Engineering, founded by Bill Wood in 1977, is based in Camarillo, California. It designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its calipers, brake rotors, master cylinders, valves, fittings and lines must be selected to suit the complete braking system.

Fitment & Compatibility
This red-caliper SRP configuration requires the Chevrolet 12-bolt C-clip-eliminator mounting arrangement. Measure the actual axle and identify the eliminator before selection. DS-267 states 2.81-inch offset, while the product page states 2.91 inches; obtain Wilwood confirmation of the complete assembly. The table below provides conditional vehicle context, so its front-spindle descriptions do not identify the rear housing end.
