Wilwood Rear Plain-Rotor Brake Kit with Red D154 Calipers, Camaro/Chevelle/Apollo/Beaumont/442 1964–1974, Measured 12-Bolt C-Clip Rear End

This red Wilwood rear package supplies plain vented rotors, D154 calipers and internal parking-brake assemblies for a matching C-clip 12-bolt axle. The rotor diameter is 12.19 inches, with alignment based on the specified 2.75–2.81-inch axle offset. It is an axle-dependent conversion rather than a fit established by front suspension parts. 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. Its product range serves motorsport, street-performance, and specialized applications, with individual components selected to match the requirements of the complete brake system.

Fitment & Compatibility

Confirm rear flange and bearing details against DS860 before using the Camaro, Chevelle, Apollo, Beaumont or 442 vehicle entries. Front Ridetech pin/hub spindle options in those rows do not identify the rear assembly and require clarification. Inspect wheel-stud diameter, axle-flange size and suspension clearance. Supply the parking-cable connections and brake hoses separately. The conditional 16-inch wheel requirement still needs a full profile check, including for any potential 15-inch fit.

Check the individual year, model, submodel and equipment conditions in the fitment table below before ordering.
