Caliper Highlights:

Wilwood's GP 300 and GP 310 motorcycle calipers have been designed and engineered for use on 1984-2003 Harley-Davidson® Motorcycles. Built around a 4-piston, high performance powerhouse, these billet aluminum calipers bring distinctive, bolt-on styling: Direct leg-mounted calipers are available for all single and dual disc models (except Springer and 4-speed FL models), as well as the 1983 XR 1000.

Rear calipers are available for all Softail® , Dyna, and touring models, utilizing unique bracket designs that combine the right elements of strength and style.

The GP 300 and GP 310 calipers are available in polished or brilliant chrome finishes, with the added performance characteristics found in Wilwood's racing calipers: stainless steel pistons to reduce brake fade while resisting corrosion and high temperature piston seals for extended life, controlled retraction and drag free operation. Additional features include bright-finish bleed screws and hardware, exclusive pad anti-rattle clip, and brake pads designed to operate in the widest range of temperatures and environments, utilizing our industry leading stainless steel rotor compatible formulation.
