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

DynaPro Lug Mount Caliper

The DynaPro Lug Mount (DP) caliper, precision machined from forged aluminum, represents the newest generation of calipers available as an upgrade or replacement for applications previously utilizing 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 billet. 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 aluminum block.

The body design, generated through Finite Element Analysis (FEA), incorporates a highly ribbed 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 corresponding decrease in fluid volume displacement translate into increased clamping efficiency with less pedal travel. In short, a firm, responsive pedal with outstanding stopping power. The DynaPro incorporates other refinements 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 disassembly, but lower pad supports have been eliminated to create a trimmer profile that more readily fits into tight clearance applications. id="MainContent_lblPistType" class="Gray11B">Stainless Steel Dust Boot No
