Wilwood 120-14698-BK Dynapro Radial Mount Dust Seal Brake Caliper - 4-Piston Black

The Wilwood DynaPro-DS (120-14698-BK) is a four-piston radial mount disc brake caliper engineered for superior strength and durability in demanding driving conditions. This black-finished caliper combines the precision of radial mounting with dust-sealed protection, making it an ideal choice for sports, rally, and off-road applications.

Advanced Forging Technology:

The DynaPro's exceptional strength comes from stress-flow forging, a specialized process that re-aligns the internal grain structure of the metal to flow within the contour of the caliper body. This manufacturing method produces a component with significantly greater strength compared to machined billet or cast alternatives.

FEA-Optimized Design:

• Finite Element Analysis (FEA) generated body design featuring radial transitions between piston bores and caliper bridges
• Eliminates machined steps and shoulders in critical stress areas for enhanced deflection resistance
• Minimizes body separation under high load conditions
• Reduced structural deflection and volume displacement for firm pedal feel and consistent stopping power

Dust Seal Protection:

Features dust-sealed stainless steel pistons that provide maximum protection against track and road-born debris in intermediate to high temperature braking applications. The dust seal configuration is engineered for environments where contamination is a concern while maintaining thermal performance.

Specifications:

• Mounting Style: Radial mount
• Piston Configuration: Four-piston design
• Piston Type: Dust-sealed stainless steel
• Maximum Rotor Diameter: 12.19 inches
• Finish: Black
• Application: Sports, rally, off-road, and performance street

The DynaPro-DS delivers the sleek profile and mounting versatility required for modern brake system installations while providing the structural integrity needed for aggressive driving. The radial mount design simplifies installation and allows for precise caliper positioning relative to the rotor.
