Wilwood Rear Drilled/Slotted D154 Conversion for Big Ford New Style, Black Calipers, 2.50-Inch Offset; Lincoln Town Car (1990), Axle Verification Required

This Wilwood rear kit pairs black D154 calipers with drilled/slotted SRP rotors and internal parking-brake shoes. The 12.19-inch rotor package is built for a Big Ford New Style housing end at 2.50-inch axle offset. Any 1990 Lincoln Town Car installation depends on those measured axle details, not just the vehicle application name. 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

Compare the axle to DS854 before selecting this conversion. Establish bearing retention, housing flange dimensions and rotor register fit, and confirm the Town Car application with Wilwood. Wheel-stud size and axle-flange diameter must also suit the hats. The parking cables and brake hoses are separate installation items. Check the completed caliper/rotor section against the wheel template; the listed 16-inch minimum is conditional and does not exclude the need to measure a proposed 15-inch wheel.

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