Wilwood 120-10000 Narrow DynaPro Four Piston Radial Mount Brake Caliper

The Wilwood Narrow DynaPro four piston radial mount caliper combines versatile radial mounting with a sleek profile, superior strength, and extreme durability in demanding conditions. Weighing as light as 3.58 pounds, the DynaPro has become a favored choice for sports, rally, and off-road driving applications where weight reduction and reliable performance are critical.

Advanced Stress-Flow Forging Technology:

The strength of the DynaPro caliper comes from its innovative stress-flow forging process, which 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 superior strength compared to machined billet parts or castings, providing exceptional resistance to deflection under high loads.

FEA-Optimized Design:

The caliper body features a finite element analysis (FEA) generated design with radial transitions between the piston bores and caliper bridges. This eliminates machined steps and shoulders in critical strength areas, substantially increasing resistance against deflection and body separation during high-load braking. Structural deflection and volume displacement testing have proven the efficiency of this design, delivering a firm pedal with outstanding stopping power.

Key Features:

• Four piston radial mount design for versatile mounting options
• Narrow profile fits rotors up to 12.19 inches in diameter
• Heavy wall stainless steel pistons provide corrosion resistance and reduce heat transfer from pads
• Compatible with optional Thermlock pistons for maximum thermal protection in sustained high-heat applications
• Stainless Steel SRS (Spread Retention System) bridge plates eliminate caliper bridge wear from pad gouging
• SRS plates dampen noise and vibration during brake engagement
• Internal fluid passages eliminate the need for external crossover tubes
• Four corner bleeder screws allow effective air evacuation regardless of mounting location
• Designed for thin pad applications

The Wilwood 120-10000 Narrow DynaPro caliper incorporates exclusive performance enhancements that make it an ideal upgrade for high-performance braking systems requiring compact dimensions without sacrificing strength or reliability.
