Description

Wilwood DynaPro Narrow Lug-Mount forged billet calipers represent the newest generation of brake calipers available as an upgrade or replacement for applications previously using the long-standing Dynalite model series. DP calipers combine pure race technology with several new exclusive Wilwood performance enhancements. A sleek profile with superior strength and a forged machined finish provide the performance and looks for competition or show. They're especially designed for limited outboard rotor hat clearance and narrow swept area rotors.

The strength of forged DynaPro low-profile calipers is a combination of process and design. This series is designed using stress-flow forged from premium grade billet aluminum. Stress-flow forging realigns the grain structure of the metal within the contour of the body design. This process produces a part with superior strength over parts simply machined from straight grained blocks of billet. The FEA generated body design incorporates a highly fortified radial transition that eliminates steps and shoulders between the piston housings and the bridges. Incorporating a radius in this critical area substantially increases resistance to deflection and caliper body separation under load. Structural deflection and volume displacement testing have proven the efficiency of this innovative design. Reductions in overall deflection, and the subsequent decreases in fluid volume displacement, translate to increased clamping efficiency with less pedal travel. The bottom line is a firm, responsive pedal with outstanding stopping power.

These brake calipers are loaded with other enhancements for performance and wider application. They feature Quick-E-Clip pad retainers that support a new design 4812 type brake pad from the top. Not only do they allow for fast pad service without caliper removal, the bottom pad supports have been removed to create a slimmer profile that can be more easily fitted into tight clearance applications. Order the calipers recommended for your vehicle.
