Product details
Red calipers and drilled-and-slotted discs identify this Mopar/Dana version. For Mopar 8-3/4 / Dana 60, 2.36-inch offset, Wilwood specifies red powder-coated 4-piston calipers and 12.19-inch SRP drilled-and-slotted rotors in this rear package. Bill Wood founded Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures disc brake systems and components including calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. This kit should be matched to the hydraulic and mechanical requirements of the complete vehicle.
Package and installation requirements
- No parking brake is included. Wilwood describes this package for applications that do not require a separate parking brake, including custom and competition installations.
Fitment & Compatibility
This kit mounts to Mopar 8-3/4-inch or Dana 60 rear housing ends with a 2.36-inch axle offset and the specified non-adjustable snap-ring axle bearings. Wilwood identifies Green MO400, Strange A1022 and Moser 9400M bearing arrangements in the installation instructions. Identify the housing end and measure the axle offset before ordering; the differential name alone is insufficient.
Before ordering, compare the wheel profile with the Wilwood clearance diagram. The stated minimum size does not establish spoke or barrel clearance for every wheel of that diameter.
