Wilwood 120-14708 Dynapro Radial Mount Dust Seal Caliper Four Piston

The Wilwood Dynapro-DS (120-14708) is a four-piston radial mount disc brake caliper engineered for superior performance in demanding motorsports applications. Combining the precision of radial mounting with a low-profile design, this caliper delivers exceptional strength and durability even in adverse conditions, making it ideal for sports, rally, and off-road driving.

Stress-Flow Forged Construction:

The Dynapro caliper body is manufactured using an advanced stress-flow forging process that re-aligns the internal grain structure of the aluminum to follow the contour of the caliper body. This forging method produces a significantly stronger component compared to traditional machined billet or cast calipers, with superior resistance to deflection under high braking loads.

FEA-Optimized Design:

Finite Element Analysis (FEA) engineering created a body design featuring radial transitions between the piston bores and caliper bridges. This eliminates machined steps and shoulders in critical stress areas, substantially increasing resistance against body separation and deflection. The result is a firm, consistent brake pedal feel with outstanding stopping power.

Key Features:

• Four-piston radial mount configuration for precise caliper positioning
• Dust-sealed stainless steel pistons protect against track and road debris
• Suitable for rotors up to 12.19 inches in diameter
• Anodized aluminum finish for corrosion resistance and appearance
• Designed for intermediate to high temperature braking applications
• Compatible with optional Thermlock insulated pistons for extreme heat protection
• Proven performance through structural deflection and volume displacement testing

The Dynapro-DS caliper represents Wilwood's commitment to engineering excellence, offering racers and performance enthusiasts a lightweight, high-strength braking solution that maintains consistent performance under the most challenging conditions.
