Wilwood Rear Red D154 Brake Conversion, Big Ford 2.36-Inch Axle Offset, Drilled/Slotted Rotors; Conditional Lincoln Town Car 1990

Red D154 calipers and SRP drilled/slotted rotors distinguish this Wilwood rear parking-brake package. The brackets are selected for a Big Ford housing end at 2.36-inch axle offset. The Town Car application is conditional on the physical rear assembly; the badge and year do not prove the required flange or bearing dimensions. 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. Its product range serves motorsport, street-performance, and specialized applications, with individual components selected to match the requirements of the complete brake system.

Fitment & Compatibility

Verify the housing against DS858 and record the axle measurements before purchase. Manufacturer confirmation is needed for the listed 1990 Lincoln installation. Inspect the axle flange and studs, checking clearance around the shocks and the internal parking assembly. Parking cables and hydraulic hoses are additional. Use the conditional 16-inch wheel section to check the caliper envelope; selected 15-inch designs may work only when the complete drawing fits behind their spokes and inside the barrel.

Check the individual year, model, submodel and equipment conditions in the fitment table below before ordering.
