Product details
The Wilwood Billet Narrow Dynalite Radial is a four-piston hydraulic caliper with 1.88-inch stainless bores and outboard fluid inlets. This Type III anodized version is built for a nominal 0.38-inch rotor width and uses 4.75-inch radial mounting centers. Its narrow rotor envelope and radial attachment distinguish it from the lug-mount Dynalite variants. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, Wilwood designs and manufactures disc brake systems and parts for motorsport, street-performance and specialized applications, from calipers and rotors to master cylinders, valves, fittings and brake lines.

Fitment & Compatibility
Plan this caliper around an 11.75–12.19-inch-diameter rotor within the specified 0.32–0.38-inch width range. A bracket for 4.75-inch radial centers must locate the caliper over the rotor centerline at the correct radius. Leave clearance for the outboard inlet and its 1/8-27 NPT fitting, and select the listed 7816 or 7216 pad shape to suit the complete brake assembly.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
The Billet Narrow Dynalite radial caliper uses four stainless pistons, internal fluid transfer and type 7816 pads. Its 4.75-inch stud spacing differs from the 3.50-inch lug-mount Narrow Dynalite layout.
