Wilwood 120-17771 Forged Billet Dynalite-M Disc Brake Caliper

The Wilwood Forged Billet Dynalite-M Disc Brake Caliper represents a significant advancement in lightweight, high-performance braking technology. Engineered with enhanced outboard clearance and weighing just 2.80 pounds, this caliper delivers professional-grade stopping power in a compact, ultra-light package.

Advanced Forging Technology:

The stress-flow forging process realigns the metal's grain structure to follow the contour of the caliper body, eliminating the structural weaknesses found in traditional billet machining. This results in superior strength and resistance to deflection under extreme braking loads. The FEA-generated radial transition design between the piston housing and caliper bridges further increases rigidity, reducing flex and fluid volume displacement for improved pedal feel and responsiveness.

Key Features:

• Stress-flow forged construction for maximum strength-to-weight ratio
• Starting weight of 2.80 lbs—lightest in class
• SRS stainless steel bridge plates prevent pad gouging and eliminate rattle
• Stainless steel pistons resist corrosion and reduce heat transfer
• High-temperature seals for reliable performance under extreme conditions
• Internal fluid passages eliminate external brake lines
• Four-corner bleed screws allow universal mounting (front, rear, left, or right)
• Signature bright black anodized finish for corrosion resistance

The combination of reduced deflection, decreased fluid displacement, and superior structural integrity translates to a taller brake pedal, shorter stopping distances, and consistent performance under demanding track and street conditions. Ideal for performance upgrades, racing applications, and custom brake system builds.
