Wilwood 120-17192 Dynapro Narrow 4-Piston Universal Radial Brake Caliper, Red.

Narrow DynaPro Radial Brake Caliper

Wilwood Narrow DynaPro Radial Mount Four Piston Brake Calipers combine the versatility of radial mounting with a sleek profile, superior strength, and extreme durability in adverse conditions. Tipping the scales at a mere 3.58 pounds, the DynaPro has become the caliper of choice for a wide range of road racing, rally, and off-road applications.

DynaPro strength is a combination of process and design. The true stress-flow forging process realigns the internal grain structure of the metal to flow within the contour of the caliper body. This produces a part with superior strength over machined from billet or cast parts.

Body design, generated by finite element analysis (FEA), features a radial transition between the piston bores and the caliper bridges. This eliminates machined steps and shoulders in this critical strength area and substantially increases resistance to deflection and body separation under high loads. Structural deflection and volumetric displacement tests have proven the effectiveness of this innovative design. In short, it delivers a firm pedal with outstanding stopping power. Narrow DynaPro calipers accommodate up to 12.19” rotors and feature thick-walled stainless steel pistons for added protection against corrosion and pad heat transfer. All DynaPro calipers can also be equipped with Thermlock pistons for maximum thermal protection in sustained high heat applications. The DynaPro incorporates other Wilwood-exclusive performance enhancements. Stainless steel SRS bridge plates eliminate caliper bridge wear from pad drag while dampening noise and vibration during engagement. Internal fluid passages eliminate the need for external cross-over tubes and four corner bleed screws allow for effective evacuation of gasses regardless of mounting location. class="Gray11B">4 Piston Area (in²) 3.00 Piston Type Stainless Dust Boot No
