Wilwood Red Superlite Front Kit, 12.19-Inch SRP Rotors, Jeep CJ5/CJ7/Scrambler (1982–1986)

Red four-piston Superlite calipers and SRP rotor faces identify this Wilwood front conversion for the listed 1982–1986 Jeep CJ configurations. The 12.19-inch vented rings mount to separate hats over the matching original hubs. It is a brake-package conversion rather than a replacement front axle, and the original spindle and hub geometry must be established before ordering. 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

Compare the exact model, year and trim with DS926 and the application rows. Inspect the hub before performing the specified preparation and fitting the hat; replace the OE grease seal as directed. Hydraulic hoses are ordered separately and must accommodate lift height, steering and suspension movement. The wheel requires a full barrel and spoke assessment around the caliper, followed by verification of front/rear system balance.

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