Product details
The Wilwood Forged Dynapro 6A is a left-hand hydraulic caliper with six differential-bore stainless pistons. This Type III anodized version pairs 1.62/1.12/1.12-inch bores with a nominal 1.10-inch rotor width, 5.25-inch lug centers and a reinforced bridge. Match its 4.04-square-inch piston area to the intended brake balance. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. Its motorsport, street-performance and specialized brake range spans calipers, rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility
Use the left-hand caliper in the orientation specified by the brake assembly, with an accessible upper bleed point. The rotor must fall within the 10.00–13.00-inch diameter envelope and 1.04–1.13-inch width range; check the lug offset, wheel clearance and type 6712 pad sweep before installation. Confirm the 1/8-27 NPT hose connection and hydraulic balance when replacing a caliper with a different piston arrangement.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
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.
Ask PMB Performance for help comparing this caliper with your existing assembly. Our over 20 years of experience are most useful when you provide rotor size, mounting details and the current piston configuration.
