Wilwood 120-10000-RD Narrow DynaPro Four Piston Radial Mount Brake Caliper

The Wilwood Narrow DynaPro four piston radial mount caliper delivers exceptional performance with a lightweight design weighing just 3.58 pounds. This stress-flow forged aluminum caliper combines the versatility of radial mounting with superior strength and extreme durability, making it ideal for sports, rally, and off-road applications.

Advanced Engineering:

• Stress-flow forging process re-aligns the internal grain structure for superior strength over billet or cast calipers
• FEA-generated body design with radial transitions between piston bores and bridges eliminates stress concentrations
• Increased resistance against deflection and body separation under high loads for firm pedal feel
• Fits rotors up to 12.19 inches in diameter

Performance Features:

• Heavy wall stainless steel pistons provide enhanced corrosion resistance and reduced heat transfer
• Compatible with optional Thermlock pistons for maximum thermal protection in sustained high-heat conditions
• Stainless Steel SRS bridge plates eliminate caliper bridge wear from pad gouging
• Internal fluid passages eliminate external crossover tubes for clean installation
• Four corner bleeder screws allow effective air evacuation regardless of mounting orientation
• Reduced noise and vibration during braking engagement

The Narrow DynaPro's radial mount design offers flexible installation options while maintaining the structural integrity needed for demanding racing and high-performance street applications.
