The Forged Narrow Dynalite is a four-piston competition caliper with 3.50-inch lug mounting centers. Top-loading pads and internal fluid passages simplify service, while the narrow mounting pattern must match the existing tabs or bracket.
Fitment & Compatibility
Compare the existing caliper’s piston area, rotor capacity and mounting pattern. Matching the body family alone does not guarantee that the replacement will clear the wheel or preserve pedal travel.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
