Wilwood Right Red Forged Dynapro 6A, 6-Piston Caliper for 0.81-Inch-wide Rotor with 5.25-Inch Lug Centers

This Wilwood Forged Dynapro 6A is a right-hand 6-piston brake caliper with a red finish for a nominally 0.81-inch-wide rotor. Its 5.25-inch lug mounting centers and 1.62/1.12/1.12-inch piston bores must match the brake assembly. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components, including calipers, rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.

The DP6A combines a six-piston differential-bore arrangement with a reinforced bridge and 5.25-inch lug mounting. Check piston area as well as rotor width when replacing an earlier Dynapro or Dynalite caliper.

Fitment & Compatibility

For a replacement, compare the entire caliper specification rather than the finish or logo. On an adapted system, establish rotor alignment and piston-area requirements before choosing the mounting bracket.

This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.

For a brake system assembled from individual components, PMB Performance brings over 20 years of experience. Contact us with the rotor, caliper and bracket information so we can help check the combination.
