Experience unparalleled braking performance with our Four-Piston Differential-Bore Caliper. This caliper features differential bore pistons that apply a different force at both the leading edge and the trailing edge of the pads to ensure superior braking. Designed for dual-disc applications, please note that separate purchase of a left and right front caliper is required. Each caliper includes necessary components such as brake pads, a bleeder screw, and a 3/8"-24 banjo bolt. Proudly made in the U.S.A., our calipers listed for 00-03 XL models will also fit 04-13 XL models when paired with a 9/16" bore master cylinder. However, please be advised that they will not fit FXD, FXR, or XL models with spoke wheels.
