Product details
Red Dynalite calipers pair with 12.19-inch Wilwood SRP rear rotors on Chevy 12-bolt C-clip axles. Check offset and retain the specified axle ends. 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 version requires the OE C-clip axle configuration and excludes special housing ends and C-clip eliminators. Confirm the housing, bearing retention and measured offset rather than choosing by the modified-vehicle examples below. The current page states 2.91-inch offset and DS-121 states 2.81 inches; resolve that difference with Wilwood before purchase. Select flexlines separately and check the wheel drawing.
