Product details
This rear assembly pairs black XRS4R calipers with 14.00 x 1.10-inch drilled/slotted discs. The Big Ford flange brackets require the specified 2.50-inch axle offset, and the internal-shoe parking brake needs a separately chosen cable connection. Wilwood Engineering, based in Camarillo, California, has designed and manufactured disc brake systems since its founding by Bill Wood in 1977. The range spans calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.

Fitment & Compatibility
This 14-inch rear kit is selected by the Big Ford New Style housing end and its 2.50-inch axle offset. Check the worksheet against the axle register, bearing and flange dimensions before checking wheel clearance around the larger rotor. A vehicle listing, including the 1990 Lincoln Town Car with rear drums, does not substitute for these axle measurements. Internal parking shoes are supplied inside the hats. Complete their connection with separately selected cables, attachment hardware and any needed adapters; brake flexlines are also separate. Consult the fitment table below for the individual year, model and equipment details. Nominal minimum wheel diameter: 18 in; 457.2 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.
