Wilwood Rear Dynalite Drilled Brake Kit, Olds/Pontiac End, Chevelle/442/Beaumont/Camaro/Apollo (1964–1974)

The Oldsmobile/Pontiac housing-end bracket pattern distinguishes this Wilwood rear drag kit from its Chevrolet 12-bolt counterpart. It uses drilled solid rotors, separate aluminum hats and four-piston Dynalite calipers. A vehicle may have an aftermarket rear housing with different ends, so the named applications require a physical flange and offset check. 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

Resolve the published axle-offset discrepancy before installation: the exact part page lists 2.91 inches, but DS117 identifies 2.81 inches in its heading. Wilwood should confirm the correct arrangement for the measured housing. Do not infer rear fitment from the Ridetech front-spindle entries in the application list. Check axle bearing size, hat registration, wheel studs and the full wheel-clearance envelope.

Match the individual model, year, submodel and brake configuration in the fitment table below.
