Wilwood 120-9705 Dynapro Universal Caliper, Lug Mount, 4 Piston, Silver.

DynaPro Lug Mount Caliper

The DynaPro Lug Mount (DP) caliper, forged from aluminum, represents the latest generation of calipers available as an upgrade or replacement for applications previously utilizing the Dynalite series. DP calipers combine pure race technology with several performance enhancements unique to Wilwood. A sleek profile with superior strength and high precision machined finish provide the ideal performance and aesthetic for competition or show.

The strength of the DynaPro 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 over parts simply machined from straight-grain block aluminum.

Finite Element Analysis (FEA) generated body design incorporates a highly reinforced radial transition that eliminates steps and shoulders between the piston housings and the bridges. Integrating 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. Reduced overall deflection and the resulting decrease in fluid volume displacement translates to increased clamping efficiency with less pedal travel. In short, a firm, responsive pedal with exceptional stopping power. The DynaPro incorporates other enhancements for improved performance and wider application versatility. The 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 disassembly, but lower pad supports have been eliminated to create a thinner profile that more readily fits into tighter clearance areas. id="MainContent_lblPistType" class="Gray11B">Stainless Steel Dust Boot No
