Wilwood 120-14705 Dynapro-DS Four Piston Radial Mount Disc 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.

Stress-Flow Forged Construction:

The strength of the Dynapro-DS is achieved through an advanced stress-flow forging process that re-aligns the internal grain structure of the metal to flow within the contour of the caliper body. This produces a component with superior strength compared to machined billet parts or castings, ensuring maximum durability under extreme braking loads.

FEA-Optimized Design:

The finite element analysis (FEA) generated body design features a radial transition between the piston bores and caliper bridges, eliminating machined steps and shoulders in critical strength areas. This innovative design substantially increases resistance against deflection and body separation under high load, resulting in a firm pedal feel with outstanding stopping power.

Key Features:

• Four piston radial mount configuration for versatile mounting options
• Dust-sealed stainless steel pistons provide maximum protection against track or road-born debris
• Stress-flow forged construction for superior strength and durability
• Radial transition design minimizes deflection under high-load conditions
• Suitable for intermediate to high temperature braking applications
• Accommodates rotors up to 12.19 inches in diameter
• Optional Thermlock insulated pistons available for sustained high-heat applications

Ideal for performance street, road racing, rally, and off-road applications where superior stopping power and consistent brake feel are essential.
