Product details
This Wilwood Mopar/Dana rear conversion is the 2.36-inch-offset snap-ring-bearing configuration. Black D154 twin-piston calipers operate over plain 12.19-inch vented rotors, with internal shoes providing the parking brake. The package includes the matched brackets and parking assemblies for the specified rear flange geometry. 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
The snap-ring bearing version of the Mopar/Dana end must be identified before selecting this package. DS859 and the axle worksheet provide the flange and offset references; measure the rear assembly while its bearing and retainer arrangement can be seen. Inspect the rotor-hat registration and the axle flange envelope, and check that the wheel studs have suitable diameter and engagement. The parking bracket must clear the shocks and surrounding suspension. Supply a correctly restrained cable route separately, adjust the shoes and verify that the lever returns without binding. Hydraulic flex lines are also separate. Check the entire conditional 16-inch wheel profile; a smaller 15-inch wheel remains possible only when that full section clears.
