Wilwood 120-17192-RD Narrow DynaPro Four Piston Radial Mount Brake Caliper Red

The Wilwood Narrow DynaPro four piston radial mount caliper delivers exceptional stopping power in a lightweight, compact package designed for sports, rally, and off-road applications. Weighing just 3.58 pounds, this high-performance caliper combines the versatility of radial mounting with a sleek profile and extreme durability in adverse conditions.

Advanced Stress-Flow Forging Technology:

The DynaPro's superior strength comes from stress-flow forging, a specialized process that re-aligns the internal grain structure of the metal to flow within the contour of the caliper body. This produces a significantly stronger component compared to machined billet or cast alternatives. The FEA-generated body design features radial transitions between piston bores and caliper bridges, eliminating machined steps and shoulders in critical strength areas to substantially increase resistance against deflection and body separation under high loads.

Key Features:

• Four piston radial mount design for versatile installation options
• Fits rotors up to 12.19 inches in diameter
• Heavy wall stainless steel pistons provide superior corrosion resistance and reduced heat transfer
• Optional Thermlock pistons available for maximum thermal protection in sustained high-heat applications
• Stainless Steel SRS bridge plates eliminate caliper bridge wear from pad gouging while dampening noise and vibration
• Internal fluid passages eliminate the need for external crossover tubes
• Four corner bleeder screws allow effective air evacuation regardless of mounting location
• High-visibility red finish

The combination of advanced forging technology, innovative design, and premium materials delivers a firm pedal feel with outstanding stopping power. Structural deflection and volume displacement testing confirm the efficiency of this proven design for demanding braking applications.
