Wilwood 120-14332 Forged Narrow Mount 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. Built using advanced stress-flow forging techniques, this caliper delivers superior strength and durability compared to traditional billet-machined designs.

Advanced Forging Technology:

The stress-flow forging process re-aligns the metal's grain structure to follow the contour of the caliper body, eliminating the internal grain structure interruptions that occur during conventional billet machining. This results in a significantly stronger component that resists deflection and separation under extreme braking loads.

FEA-Optimized Design:

Utilizing Finite Element Analysis (FEA), Wilwood engineered a radial transition design that eliminates steps and shoulders between the piston housing and caliper bridges. This smooth radius transition substantially increases resistance to structural deflection and volume displacement, making the FNDL the strongest caliper in its class.

Key Features:

• SRS stainless steel bridge plates prevent 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 maintain performance under extreme conditions
• Stainless steel pistons eliminate corrosion and retard heat transfer from brake pads
• Internal fluid passages eliminate external brake line tubes for clean installation
• Four-corner bleed screws enable simple air evacuation and allow mounting in any front, rear, left, or right position
• Durable Type III hard anodized finish (legacy units feature black anodize, newer production features gray anodize)
• Polished finish available in select piston sizes and rotor widths

This caliper combines proven Wilwood performance features with innovative engineering to deliver maximum strength, reliability, and versatility for demanding motorsports applications.
