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

The Wilwood Forged Billet Dynalite-M Disc Brake Caliper represents a significant advancement in lightweight, high-performance brake caliper design. Specifically engineered to enhance outboard clearance, this forged caliper delivers exceptional strength while maintaining a remarkably low weight starting at just 2.80 pounds.

Advanced Forging Technology:

Unlike machined billet calipers, the stress-flow forging process re-aligns the metal's grain structure within the contour of the caliper body, eliminating internal grain structure breaks that occur during traditional machining. The FEA-generated radial transition design removes steps and shoulders between the piston housing and caliper bridges, substantially increasing resistance to deflection and caliper separation under high brake loads. Testing has proven this design significantly reduces structural deflection and fluid volume displacement, resulting in improved clamping efficiency with less pedal travel for a firmer pedal feel and better stopping power.

Premium Performance Features:

• Stainless steel SRS (Stainless Rotor Sleeves) bridge plates eliminate bridge wear from pad gouging and extend caliper service life
• Spring-loading action of SRS plates eliminates pad rattle and dampens vibration harmonics that cause brake squeal
• High-temperature seals and stainless steel pistons resist corrosion and retard heat transfer from brake pads
• Internal fluid passages eliminate external brake lines for cleaner installation
• Four-corner bleeder screws enable simple air evacuation and allow universal mounting in any front, rear, left, or right position
• Signature bright black anodized finish resists corrosion while maintaining a high-tech appearance

The Forged Billet Dynalite-M combines cutting-edge manufacturing technology with proven Wilwood engineering to deliver the strongest caliper in its class, making it an ideal choice for street performance, road racing, and autocross applications.
