Product details

Red powder-coated Dynalite calipers distinguish this Wilwood rear disc and parking-brake conversion. It supplies 12.19-inch SRP rotors and internal shoe assemblies for the specified Strange Engineering floater with 3.49-inch offset. This is a matched axle-end package, intended to be verified by measurements rather than assigned a vehicle-model fit from an axle brand. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Check the housing-end hole spacing and register, and measure from the housing flange to the wheel-side axle face. The supplied backing plates and brackets must seat correctly on that arrangement. DS890 provides the mounting and wheel-clearance dimensions. Keep cable routing as straight as practical and select mechanical connections and hydraulic hoses separately, with full suspension travel and wheel clearance checked before use.
