Wilwood 120-14333 Forged Narrow Dynalite Disc Brake Caliper

The Wilwood Forged Narrow Mount Dynalite (FNDL) caliper is engineered for high-performance competition applications including late models, modifieds, sprint cars, off-road racing, and road racing. This caliper represents the strongest design in its class, utilizing advanced stress-flow forging technology to maximize structural integrity under extreme braking loads.

Advanced Forging Technology:

The stress-flow forging process re-aligns the metal's grain structure within the contour of the caliper body, eliminating the grain structure breaks and interruptions that occur when machining from straight billet. 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 load. Structural deflection and volume displacement testing has proven the Forged Narrow Mount Dynalite outperforms all existing calipers in this size class.

Performance Features:

• SRS stainless steel 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
• Stainless steel pistons resist corrosion and retard heat transfer from brake pads
• High-temperature seals for reliable performance under extreme conditions
• Internal fluid passages eliminate external brake line tubes
• Four-corner bleeder screws enable simple air evacuation and allow universal mounting in any front, rear, left, or right position
• Finished in Black Anodize (legacy units) or Type III Gray Anodize (newer production)

This caliper combines innovative structural engineering with proven Wilwood performance features to deliver exceptional braking power and durability for demanding motorsports applications.
