Wilwood Forged Dynapro 6A Left Thermlock Brake Caliper, Type III Anodized / 1.62/1.38/1.38-Inch Bore / 0.38-Inch Rotor Width

For a brake system using a 0.38-inch-wide rotor, this Type III anodized Wilwood Forged Dynapro 6A provides 6 pistons with 1.62/1.38/1.38-inch bores. Left-hand mounting is specified. The caliper attaches on 5.25-inch lug centers. Founded in 1977 by Bill Wood, Camarillo, California-based Wilwood Engineering manufactures disc brake components for motorsport, street-performance and specialized uses. Its range covers calipers, rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility

Check pad depth against the rotor’s usable friction annulus. Rotor-hat clearance, mounting offset and the wheel’s inner profile must also be checked with the caliper drawing.

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.

PMB Performance has worked with parts and brake fitment for over 20 years. Supply the installed caliper identity and the rotor and bracket measurements for a practical compatibility check.
