Product details
Red D154 calipers clamp SRP drilled/slotted rings in this Wilwood Mopar/Dana rear conversion. The vented rotors are 12.19 inches in diameter, and internal parking shoes work independently of the hydraulic calipers. The hardware is dedicated to a 2.36-inch-offset housing with snap-ring axle bearings. 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
Check the axle-end drawing in DS859 and measure the actual bearing, flange and offset. Confirm that the rotor hat clears the axle flange and fits the wheel studs, with any machining completed as directed before assembly. Inspect shock clearance and select the separate parking-cable and hydraulic connections. Wilwood lists a conditional 16-inch wheel minimum, while some 15-inch wheels are possible only after the full caliper profile has been tested against the wheel section.
