Wilwood Type III Anodized Forged Dynapro 6A Thermlock Brake Caliper, Right, 1.62/1.38/1.38-Inch Pistons / 0.38-Inch-wide Rotor

A 6-piston Wilwood Forged Dynapro 6A for right-hand installation, this Type III anodized caliper works around a nominally 0.38-inch-wide rotor. Its 1.62/1.38/1.38-inch bore configuration and 5.25-inch lug centers are the principal dimensions to compare. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, Wilwood designs and manufactures disc brake systems and parts for motorsport, street-performance and specialized applications, from calipers and rotors to master cylinders, valves, fittings and brake lines.

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

Confirm rotor diameter as well as thickness, and allow for pad and caliper clearance inside the wheel. The mount pattern is a dimensional requirement rather than a vehicle fitment guarantee.

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.
