Wilwood 120-14704 Dynapro-DS Four Piston Radial Mount Disc Brake Caliper

The Wilwood Dynapro-DS four piston dust seal radial mount caliper (DPR-DS) delivers exceptional stopping power with superior durability for sports, rally, and off-road applications. This high-performance disc brake caliper combines the versatility of radial mounting with a sleek, low-profile design engineered to withstand the most demanding driving conditions.

Advanced Stress-Flow Forging Process:

Unlike machined billet or cast calipers, the Dynapro-DS utilizes stress-flow forging technology that re-aligns the internal grain structure of the metal to flow within the contour of the caliper body. This manufacturing process produces a significantly stronger component with enhanced resistance to deflection and body separation under high-load braking.

FEA-Optimized Design Features:

• Radial transition between piston bores and caliper bridges eliminates stress concentrations
• Removes machined steps and shoulders in critical strength areas
• Reduces structural deflection and volume displacement for firm pedal feel
• Dust-sealed stainless steel pistons protect against debris contamination
• Suitable for rotors up to 12.19 inches in diameter
• Designed for intermediate to high-temperature braking applications

Upgrade Options Available:

The Dynapro caliper line offers multiple configurations including long-radius versions for rotors up to 13.00 inches and competition models featuring Thermlock insulated pistons for maximum heat protection in sustained high-temperature environments.

This caliper provides the strength, thermal management, and consistent performance demanded by serious enthusiasts and professional drivers alike.
