Wilwood 120-9693 Dynapro Universal Nut Mount 4-Piston Brake Caliper, Black.

DynaPro Lug Mount Brake Caliper

The DynaPro Lug Mount (DP) forged aluminum caliper represents the latest generation of calipers available as an upgrade or replacement for applications formerly using the Dynalite series. DP calipers combine pure racing technology with several Wilwood-exclusive performance enhancements. A sleek profile with superior strength and a high-precision machined finish provide the ideal performance and aesthetic for competition or show.

DynaPro strength is a combination of process and design. The DynaPro is stress-flow forged from a premium-grade aluminum slug. This process realigns the metal’s granular structure within the contour of the body design. This produces a part with superior strength to parts simply machined from straight-grain aluminum block.

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 effectiveness of this innovative design. The reduced overall deflection and subsequent decrease in fluid volume displacement translates into increased clamping efficiency with less pedal travel. In short, a firm and responsive pedal with exceptional stopping power. The DynaPro incorporates other enhancements for improved performance and application versatility. Calipers feature Quick-E-Clip pad retainers that support a 7812-type brake pad from the top. Not only does it allow for quick pad changes without caliper removal, but the lower pad supports have been eliminated to create a thinner profile that fits into tighter clearances more easily. id="MainContent_lblPistType" class="Gray11B">Stainless Steel Dust Boot No
