Product details
Designed around the symmetrical housing end used in M-W/Lamb rear-axle arrangements, this Wilwood drag brake kit uses a 2.81-inch offset. Four-piston forged calipers clamp drilled steel rotors attached to aluminum hats. This is a housing-specific competition conversion; there is no universal vehicle-model claim. 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 for motorsport, street-performance, and specialized applications.

Fitment & Compatibility
Match the symmetrical flange outline, mounting centers and bearing register to the installation drawing. The axle flange and hat must share an appropriate wheel-stud pattern and registration. Supply hydraulic hoses and fittings appropriate to the chassis, then verify caliper centering and wheel clearance before use. A car with a different housing end cannot be selected by axle brand alone.
