Narrow Dynapro Lug Mount
Narrow Mount DynaPro (NDP) forged billet calipers represent the next generation of calipers available as an upgrade or direct replacement for the popular Narrow Mount Dynalite model series with 3.50" mounting. NDP calipers combine superior strength with several new performance enhancements to make these the best "Dyna" series calipers ever built.   

The strength of the new DynaPro is a combination of process and design. NDP calipers are 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. For additional strength, all NDP calipers are fitted with center bridge bolts to provide additional resistance against separation over the center of the pads. 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.    Continue >>
