Product details

The drilled-and-slotted rotor option retains the internal-shoe parking brake and black Dynalite calipers of this BOP axle package. Each rotor's drum section encloses the parking shoes; the four-piston hydraulic caliper handles normal braking through BP-10 pads. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. It develops disc brake systems and components, designing and manufacturing calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. A correct conversion matches those individual components to the complete braking system.

Fitment & Compatibility

Confirm that both the bearing diameter and housing-to-axle-flange offset are 2.75 inches; these dimensions describe different interfaces. The kit does not supply hoses or the cable/clevis set. Verify available wheel space using DS1032 rather than wheel diameter alone.
