Billet Narrow Dynalite Radial Mount
Wilwood's newly redesigned Billet Narrow Mount Dynalite (NDLR) Radial Mount caliper series continues to grow in popularity in Sprint & Midget inboard applications. Starting at 3.00 pounds, this compact and lightweight design is now available in a radial mount configuration. Engineered with a spacer-less deign specifically for .38”, .810” and 1.00" width rotors allowing a single split bridge area for added strength. Type III Anodize finish further enhances the durability of the caliper. Billet NDLR calipers can be directly mounted over studs on a 4.75" centre mounting, 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 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 two corner bleeds and outboard inlets in the correct location for a standard Inboard mount. 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 centre 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 7816 style brake pads. These pads are available in many different PolyMatrix compounds to provide the correct brake torque and heat range for any high performance or competition application. Radial mount bracket kits are used to install a radial mount caliper in place of a tab mount caliper. Brackets are available for both Sprint and Midget Inboard and Dirt Late Model applications for various rotor diameters.
