Wilwood Rear Red D154/SRP Parking Brake Package, Chevelle/442/Beaumont/Camaro/Apollo (1964–1974), C-Clip 12-Bolt Housing at 2.75–2.81-Inch Offset

Red D154 hydraulic calipers and SRP drilled/slotted rotors distinguish this Wilwood 12-bolt rear conversion. Internal parking shoes work within the rotor hats, while the twin-piston calipers use included BP-10 pads. The required 2.75–2.81-inch offset and C-clip axle configuration must be established on the vehicle. 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

Use DS860 and the axle worksheet to measure the housing flange, offset and register. Do not infer rear fitment from the Ridetech front-spindle options attached to the Chevelle, 442, Beaumont, Camaro and Apollo application rows. Confirm the actual rear axle with Wilwood before purchase. Check flange clearance and studs, then plan parking cables and hydraulic hoses separately. Measure the wheel profile, using the conditional 16-inch drawing and checking any 15-inch alternative in full.

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