Wilwood 120-14701-BK Dynapro Radial Mount Dust Seal Brake Caliper - Black

The Wilwood DynaPro-DS (120-14701-BK) is a high-performance four-piston radial mount disc brake caliper engineered for demanding sports, rally, and off-road applications. This dust seal variant combines the convenience of radial mounting with exceptional strength and protection against debris in harsh driving conditions.

Advanced Stress-Flow Forged Construction:

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 follow the caliper body's contours. This process delivers superior strength and resistance to deflection under extreme braking loads. The FEA-optimized body design features smooth radial transitions between piston bores and caliper bridges, eliminating weak points created by machined steps and shoulders found in conventional designs.

Key Features:

• Four-piston radial mount design with sleek low-profile appearance
• Dust-sealed stainless steel pistons provide maximum protection against track and road debris
• Accommodates rotors up to 12.19" in diameter
• Stress-flow forged construction for superior strength and minimal deflection
• Black anodized finish for corrosion resistance and appearance
• Radial mounting configuration for simplified installation
• Compatible with Thermlock insulated pistons for high-heat applications (optional)
• Proven performance in intermediate to high temperature braking conditions

The DynaPro-DS delivers firm pedal feel and outstanding stopping power through its rigid body design that minimizes caliper flex and volume displacement. Ideal for performance street vehicles, road racing, rally cars, and off-road trucks requiring reliable braking performance in adverse conditions.
