Billet Narrow Dynalite
Wilwood’s Billet Narrow Mount Dynalite (NDL) caliper combines the lightweight, high torque performance of our Dynalite Series Calipers, but utilizes a thicker pad design and bolts directly onto standard Superlite 3.50” mounts. Caliper weights starting at 3.50 pounds, yet provides tremendous brake torque. The caliper is extremely compact and will easily mount in limited clearance applications. Its computer generated billet design incorporates internal fluid crossover passages to eliminate external tubes, while the extra thick 0.63” (16,0 mm) Dynalite pad is securely held in by the bridge bolt design. Standard Wilwood features include deep cup stainless steel pistons, high temperature piston seals and black anodized finish. The caliper is available in 1.75, 1.62, 1.38 and 1.12 inch piston bores for 1.25, .81, .50 and .38 inch rotor widths. The Billet NDL is ideal for many racing applications, including Late Models, Modifieds, Sprints, Off Road and Road Racers.  

Thermlock® T1 pistons are available for the Billet NDL Caliper. These pistons will effectively manage heat, reducing thermal transfer to calipers, seals and brake fluid under the most abusive conditions.   Continue >>
