Wilwood Drilled Rear Parking Conversion, Chevelle/442/Beaumont/Camaro/Apollo (1964–1974), Black D154, 12-Bolt Staggered Shocks

Drilled/slotted 12.19-inch rotors pair with black two-piston D154 calipers and internal parking shoes in this Wilwood rear conversion. It is configured for the specified 12-bolt special housing and staggered shock mounts, using a 2.81-inch axle offset. The bracket clocking differs from side to side, so a general vehicle-year match or rear-axle description is insufficient to select the package. 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

Establish flange dimensions and measured axle offset before comparing the staggered shock arrangement with the instructions. The right caliper mounts rearward of the axle while the left mounts forward; that describes rear-axle clocking, not a front brake application. The vehicle table's front-spindle references require separate rear-fitment confirmation. Select suitable lines and parking cables separately, set shoe clearance and caliper alignment, then check the full wheel diagram and complete hydraulic balance.

Match the individual year, model, submodel and equipment conditions in the fitment table below.
