The DynaPro Narrow Lug Mount (DPN) forged billet caliper represents the newest version of calipers available with narrower outboard clearance. DPN calipers combine pure race technology with several new exclusive Wilwood performance enhancements. A sleek profile with superior strength and a fully detail machined finish provide the performance. Available in Wilwood’s Type III anodize or enhanced with black or red powder coat finish.

The strength of the DynaPro Narrow is a combination of process and design. The DynaPro Narrow is stress-flow forged from premium grade billet. 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.

The DynaPro Narrow is loaded with other enhancements for performance and wider application. The calipers feature Quick-E-Clip pad retainers that support a 7812 type brake pad from the top. Not only does it 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.
