120-6453-si - Product Description

Billet Narrow Dynalite Radial Mount

Wilwood’s Billet Narrow Mount Dynalite (NDL) Radial Mount caliper series continues to grow in popularity over a wide range of racing and high performance applications. Starting at 2.70 pounds, this compact and lightweight proven performer is now available in a radial mount configuration. The Billet NDLR calipers can be directly mounted over studs, or used with a radial mount bracket kit in place of a tab mount caliper.

The Billet NDLR caliper is a compact, lightweight, and rugged caliper that provides strong clamping force from four 1.75" stainless cup pistons. The bodies are fully CNC machined from billet with internal fluid ports that eliminate external fluid tubes. Each caliper is equipped with four corner bleeds to accommodate mounting in all positions. The bridges are equipped with stainless steel anti-rattle wear plates. These plates reduce bridge wear and provide smooth, rattle free operation of the pads. A center bridge bolt adds overall caliper strength and positive retention of the top loaded pads.

All Billet NDLR calipers are designed for long service using the 0.63” (16,0 mm) thick 7216 style brake pads. These pads are available in eight different PolyMatrix compounds to provide the correct brake torque and heat range for any high performance or competition application.

Additional Notes

Radial mount bracket kits are used to install a radial mount caliper in place of a tab mount caliper. NDLR brackets use the popular 3.50" mount pattern found on Wilwood SL, NDL, and many other popular racing calipers. On applications where the tab mount bolts are difficult to access, radial mounting can drastically simplify service in the field. Radial brackets also provide two planes of adjustment for precise alignment over the disc.

Wilwood’s unique Thermlock® T1 Short Track Piston is an optional feature on our Billet NDL calipers.
