Billet Narrow Dynalite Radial Mount

The Billet Narrow Dynalite Radial Mount (NDLR) series calipers are engineered for high-performance racing applications. Weighing only 3.20 pounds, these compact calipers feature a rigid radial mount design and a spacer-less body tailored for .38”, .810”, and 1.00" width rotors. A center bridge bolt enhances overall strength and ensures secure retention of the top-loaded brake pads. The calipers are finished with a durable aluminum-oxide ceramic Mil-Spec Type III hard-anodized coating, providing excellent resistance to bore wear and surface abrasion.

These calipers can be directly mounted over studs on a 4.75" center or utilized with a radial mount bracket kit as a replacement for tab-mount calipers. Internal damping springs, fluid crossover, controlled retraction in-bore seals, and 3/8” cross bolts contribute to consistent pedal feel throughout use. They are compatible with type 7816 brake pads, offering various Wilwood compound options to suit different driving styles and track conditions.

Constructed from billet aluminum, the NDLR calipers utilize four stainless cup pistons to deliver strong clamping force. The design includes internal fluid ports that eliminate the need for external fluid tubes, two corner bleeds, and outboard inlets positioned for standard inboard mounting. Stainless steel anti-rattle wear plates on the bridges minimize wear and ensure smooth, rattle-free operation. The center bridge bolt further reinforces the caliper and secures the top-loaded pads.

Designed for longevity, the NDLR calipers use 0.63” (16.0 mm) thick 7816 style brake pads, available in various PolyMatrix compounds to provide optimal brake torque and heat range for any high-performance or competitive scenario. Radial mount bracket kits are available for Sprint and Midget Inboard and Dirt Late Model applications, accommodating various rotor diameters.
