Product details
The black Narrow Dynapro radial-mount caliper is an individual four-piston component for a brake system using a nominal 0.81-inch-wide rotor. Its 1.75-inch stainless pistons and compact 7812 pad arrangement must be matched to the hydraulic balance and bracket geometry of the complete brake assembly. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. It designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.
Technical Details

Fitment & Compatibility
Radial mounting locates this caliper on 4.75-inch centers. Check the 10.75–12.19-inch rotor diameter envelope, hat offset and wheel clearance together; these dimensions do not establish a direct vehicle application.
