Wilwood 120-14697-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 forged caliper has become a favored choice for a broad range of sports, rally, and off-road driving applications where reliability and performance are critical.

Stress-Flow Forged Construction:

The strength of the Dynapro-DS is achieved through advanced stress-flow forging, which re-aligns the internal grain structure of the metal to flow within the contour of the caliper body. This manufacturing process produces a component with superior strength compared to machined billet or cast alternatives, ensuring maximum durability under extreme conditions.

FEA-Optimized Design:

The caliper body features an FEA-generated design with radial transitions between the piston bores and caliper bridges. This eliminates traditional machined steps and shoulders in critical stress areas, substantially increasing resistance against deflection and body separation under high load. Structural deflection and volume displacement testing have proven the efficiency of this innovative design, delivering a firm pedal with outstanding stopping power.

Key Features:

• Four piston radial mount configuration for versatile installation
• Dust-sealed stainless steel pistons provide maximum protection against track and road debris
• Stress-flow forged construction for superior strength and durability
• Radial transition design minimizes deflection under high loads
• Suitable for rotors up to 12.19 inches in diameter
• Ideal for intermediate to high temperature braking applications
• Compatible with optional Thermlock insulated pistons for sustained high-heat use

The Dynapro-DS caliper is engineered for demanding applications where consistent performance and durability are essential, making it an excellent choice for performance street vehicles, track cars, rally vehicles, and off-road racing applications.
