Product details
This Wilwood Dynalite-M kit is a front drum-spindle disc conversion for 1965–1968 Chevrolet Bel Air, Biscayne, Impala and Caprice. The 11.50-inch one-piece rotor/hub castings use four-piston Dynalite-M calipers and a dedicated later-Chevrolet spindle bracket. Wilwood Engineering designs complete disc brake systems as well as calipers, rotors, master cylinders, valves, fittings and brake lines. Established by Bill Wood in 1977 and based in Camarillo, California, it serves motorsport, street-performance and specialized applications; individual parts require a matched system.

Fitment & Compatibility
Use the listed 1965–1968 Bel Air, Biscayne and Impala plus 1966–1968 Caprice drum-brake spindles. DS-1250 distinguishes this bearing/bracket interface from earlier Impala assemblies. Do not select it for a factory-disc spindle solely by model/year. Models covered: Bel Air, Biscayne, Impala and Caprice. Use the complete application table at the bottom for the precise year, submodel, brake option and note attached to each row.
With over 20 years of parts experience, PMB Performance can help compare your existing brakes and mounting dimensions with this kit. Send the relevant year, brake option and wheel profile before ordering if the installation has been modified.
