Wilwood 120-14332 Forged Dynalite Narrow Lug Mount Universal 4 Piston Brake Caliper

Forged Narrow Dynalite

Wilwood's new Forged Narrow Mount Dynalite (FNDL) brake calipers are ideally suited and widely used in numerous competition applications including late models, modifieds, sprints, off-road, and road racing. Computer-aided design and stress analysis technology is Wilwood’s latest innovation, providing substantial improvements in strength and performance over all comparable caliper models. The Forged Narrow Mount Dynalite is the strongest caliper in its class.

FNDL calipers are a direct replacement for all previous Wilwood NDL calipers and similar competitor brands, featuring 3.50" centered mount tabs. A full five bolts provide superior bridge strength and positive retention for either 7816 or 7216 top-load brake pads. The full range of PolyMatrix pad compounds is available to match the braking response and thermal range requirements of any competition application. The real stress flow forging process realigns the metal’s granular structure within the contour of the caliper body. This process eliminates the breaks and disruptions in the internal granular structure that occur when machining from a straight block. The FEA generated radial transition design eliminates steps and shoulders in the area between the piston housing body and caliper bridges. Incorporating a radius into this transition area substantially increases resistance to deflection and caliper separation under load. Structural deflection and volume displacement testing has proven the Forged Narrow Mount Dynalite caliper to outperform all other existing styles of this popular caliper size. The superior strength of this innovative design is combined with the proven performance features of previous Wilwood designs. Each caliper is equipped with Wilwood’s SRS stainless steel bridge plates. SRS plates eliminate bridge wear caused by pad abrading and extend the caliper body’s service life. The spring-like action of the SRS plates also eliminates pad rattle and dampens harmonic vibrations that contribute to squeal under braking. Other standard Wilwood features include high-temperature seals and stainless steel pistons to eliminate corrosion and retard heat transfer from the pads. Internal fluid passages eliminate the need for external tubes. Four corner bleed screws assure simple and effective air evacuation from the system and allow a caliper to be mounted in any position: front, rear, right, or left. To complete the package, legacy FNDL calipers are finished in Wilwood's exclusive black anodizing; newer production units feature a gray Type III anodize coating. Polished units are also available in certain piston sizes and disc widths.
