Wilwood 120-14701-RD DynaPro Radial Mount Dust Seal Brake Caliper - Red

The Wilwood DynaPro-DS (120-14701-RD) is a high-performance four-piston radial mount disc brake caliper engineered for demanding sports, rally, and off-road applications. Featuring dust-sealed stainless steel pistons and a striking red finish, this caliper combines race-proven performance with superior protection against harsh environmental conditions.

Stress-Flow Forged Construction:

Unlike machined billet or cast calipers, the DynaPro body is manufactured using stress-flow forging technology. This specialized process re-aligns the internal grain structure of the metal to flow within the contour of the caliper body, resulting in exceptional strength and rigidity. FEA-optimized design features radial transitions between piston bores and caliper bridges, eliminating machined steps in critical stress areas to dramatically reduce deflection and body separation under extreme loads.

Key Features:

• Four-piston radial mount design for versatile mounting options
• Dust-sealed stainless steel pistons protect against track and road debris
• Stress-flow forged body for maximum strength and minimal deflection
• Radial transition geometry eliminates weak points in high-stress areas
• Fits rotors up to 12.19 inches in diameter
• Ideal for intermediate to high-temperature braking applications
• Red anodized finish for durability and appearance
• Compatible with optional Thermlock insulated pistons for extreme heat applications

Performance Benefits:

The DynaPro-DS delivers firm pedal feel and outstanding stopping power through its rigid, deflection-resistant design. Extensive structural deflection and volume displacement testing confirm the efficiency of the radial transition body geometry, ensuring consistent brake response even under maximum load conditions.
