Product details
This big-Ford rear kit locates both black FDLI calipers forward of the axle, a meaningful difference from staggered-mount packages. Plain 12.19-inch rotor hats enclose the supplied internal parking shoes for the new-style 2.50-inch-offset arrangement. Wilwood Engineering designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977; its Camarillo, California operation serves motorsport, street-performance and specialized applications. Individual parts must match the complete brake system and its operating requirements.

Fitment & Compatibility
This rear-axle version places both service calipers ahead of the axle. It requires the new-style big-bearing Ford housing end and a 2.50-inch offset specified in DS-557; it is not the staggered-mount version. Confirm the actual installed axle dimensions for the Lincoln Town Car application in the table below, including bearing and flange clearance. The integrated drum parking system needs separately selected cables and clevises; universal kit 330-9371 is available. Hydraulic lines and fittings are also separate. Nominal minimum wheel diameter: 15 in; 381 mm. Compare the actual wheel barrel and spokes with the linked clearance drawing; diameter alone does not establish fit.
