Product details
An individual Wilwood Narrow DynaPro-P brake caliper, finished in black, is specified here. Use the 1.12/1.12-inch piston bores, 4.75-inch mounting centers and 0.95-inch rotor width to compare it with the existing brake assembly. The Wilwood disc brake range is designed and manufactured for motorsport, street-performance and specialized applications. It includes brake lines, fittings, valves and master cylinders together with calipers and brake rotors. Wilwood Engineering was founded in 1977 by Bill Wood and is based in Camarillo, California; its components must be matched to the complete braking system. Narrow DynaPro-P uses four 1.12-inch stainless pistons and the 4812 pad outline. The compact radial mount is suited to a measured bracket arrangement. Check rotor diameter and pad sweep against the installation drawing.

Fitment & Compatibility
Verify the radial mounting interface and the complete rotor-width range shown above. Axle placement is determined by the engineered brake package, not by a generic caliper designation. Account for the 1.12/1.12-inch bores when selecting the master cylinder and front-to-rear balance. Check that the 1/8-27 NPT fitting, flexline and wheel remain clear throughout their operating movement.
