Product details
The anodized DynaPro Single is a compact two-piston caliper with 1.75-inch stainless pistons. This version uses 3.25-inch lug centers and the nominal 0.38-inch rotor opening. Quick-E-Clip pad retention and replaceable bridge wear plates are features of the DPS series, while the exact mounting dimensions identify the replacement body. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. The manufacturer produces disc brake systems and components for motorsport, street-performance and specialized applications, with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Individual components are chosen to suit the complete brake system.

Fitment & Compatibility
Compare the 3.25-inch ears and 1.92-inch mount height with the bracket already installed. Rotor thickness must fall within 0.25–0.38 inch, and the pad must sit correctly on a suitable-diameter friction track. Check the inlet and bleed orientation, wheel clearance and the hydraulic sizing associated with the 2.40-square-inch piston area.
