Wilwood Rear SRP Brake Kit, Black D154 Calipers for Staggered Shocks, Big Ford New Style 2.50-Inch Axle Offset; Lincoln Town Car 1990 With Confirmed Axle

Black D154 calipers and drilled/slotted rotors form this Wilwood staggered-shock rear conversion. The left service caliper sits ahead of the axle, while the right sits behind it to suit the specified shock arrangement. Internal parking shoes and 12.19-inch vented rotors match the Big Ford New Style housing at 2.50-inch offset.

The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines.

Fitment & Compatibility

Read DS863 with the actual shock arrangement visible. The left bracket locates its service caliper ahead of the axle, and the right locates its caliper behind; substituting two brackets of another clocking can cause interference. Verify the New Style housing, bearing retention, offset and rotor register, then confirm the 1990 Lincoln Town Car application with Wilwood. Check the hat's flange and stud clearance. Parking-cable connections are additional and must pull and release the shoe assemblies without tight bends or uncontrolled sheath movement. Select hydraulic hoses for full axle travel separately. A wheel must match the conditional 16-inch caliper section in full; a 15-inch wheel cannot be accepted from diameter alone.

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