Wilwood 120-14706-BK Dynapro-DS Four Piston Radial Mount Brake Caliper

The Wilwood Dynapro-DS four piston dust seal radial mount caliper (DPR-DS) combines the versatility of radial mounting with a sleek profile, superior strength, and extreme durability in adverse conditions. This caliper has become a favored choice for a broad range of sports, rally, and off-road driving applications where performance and reliability are critical.

Key Features:

• Stress-flow forged construction re-aligns internal grain structure for superior strength over machined billet or cast parts
• FEA-generated body design with radial transitions between piston bores and caliper bridges eliminates machined steps in critical stress areas
• Dust-sealed stainless steel pistons provide maximum protection against track and road debris
• Radial mount design offers flexible installation options and clean aesthetic
• Compatible with rotors up to 12.19 inches in diameter
• Proven resistance against deflection and body separation under high loads for firm pedal feel and outstanding stopping power
• Optional Thermlock insulated pistons available for maximum thermal protection in sustained high-heat applications

The Dynapro-DS delivers exceptional braking performance through advanced engineering and materials. The stress-flow forging process creates a stronger, more durable caliper body that resists the extreme forces generated during hard braking. Structural deflection and volume displacement testing have validated the efficiency of this innovative design, ensuring consistent pedal feel and reliable performance in demanding intermediate to high-temperature driving conditions.
