Wilwood Red Right DP6A Brake Caliper with 5.25-Inch Lug Centers and 1.62/1.12/1.12-Inch Bores

This red Wilwood DP6A is the right-hand, nominal 1.10-inch rotor-width version of the Forged Dynapro 6A caliper. Six stainless pistons use a 1.62/1.12/1.12-inch bore combination, while 5.25-inch lug mounting locates the forged aluminum body. It is an individual hydraulic brake component whose bracket, rotor and master-cylinder requirements must agree. 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

Begin with the rotor measurement: this version permits 1.04–1.13 inches of width and a 10.00–13.00-inch diameter. Position the type 6712 pad footprint fully on the friction surface, and check the lug offset against the 2.03-inch mounting height. The red finish does not establish interchangeability with other DP6A bore or width options; verify hose clearance at the 1/8-27 NPT inlet.

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