Product details
A 0.95-inch rotor-width specification and 1.12/1.12-inch piston bores identify this Wilwood Narrow DynaPro-P brake caliper. The red finish is applied to the exact component described below; match the mounting bracket before replacement. Based in Camarillo, California, Wilwood Engineering has its origins in the company Bill Wood founded in 1977. Its designs and manufactured disc brake products cover calipers and rotors alongside master cylinders, valves, fittings and lines. Motorsport, street-performance and specialized installations each require components selected for the complete 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.
