Wilwood Forged Dynapro Low Profile Dust Seal Caliper, Red / 5.25-Inch Mount / 0.81-Inch-wide Rotor

Red finish and 1.12-inch bores distinguish this Wilwood Forged Dynapro Low Profile Dust Seal configuration. It is a 4-piston brake caliper for 0.81-inch-wide rotors, with 5.25-inch lug attachment centers. 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.

This low-profile, dust-sealed Dynapro is designed around type 4812 pads for limited outboard rotor-hat clearance and narrower swept areas. It uses 5.25-inch lug centers, but pad depth and body clearance must be checked before substituting it for a taller Dynapro or Dynalite.

Fitment & Compatibility

Compare the existing caliper’s piston area, rotor capacity and mounting pattern. Matching the body family alone does not guarantee that the replacement will clear the wheel or preserve pedal travel.

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

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.
