Wilwood Red D154 Rear Brake Kit for Jeep Wrangler (1997–2002), Dana 35 SRP Parking Conversion

Red floating D154 calipers and drilled/slotted vented rotors identify this Wilwood rear conversion for the stated Jeep Dana 35 application. The service calipers use two pistons each, while internal parking shoes retain a mechanically actuated parking function. Match the non-ABS housing end and 2.56-inch axle offset before selecting the 12.19-inch rotor 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

Use DS920 to verify flange spacing, register and wheel-stud arrangement. The included hydraulic flex lines must be routed for the actual suspension travel, especially on a modified Wrangler. Mechanical cables, clevises and adapters are separate. Check the whole caliper envelope inside the wheel: the 16-inch screening value and conditional 15-inch note both require confirmation against barrel and spoke dimensions rather than model-year assumptions.

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