PRODUCT DESCRIPTION
GP310 Motorcycle Front Disc Brake (2000-2007)
Wilwood's GP310 motorcycle disc brake caliper has been designed and engineered for use on 2000-2007 Harley-Davidson® motorcycles. Built around a powerful, high-performance 4-piston power plant, this billet aluminum caliper provides a distinctive style and easy installation: direct leg-mount calipers are available for all single and dual disc models (except Springer and 4-speed FL models). Rear calipers are available for all Softail®, Dyna, and Touring models, with unique bracket designs that combine the right strength and style. The GP310 caliper is available in polished, brilliant chrome, or black finishes, with the added performance features of Wilwood's racing calipers: stainless steel pistons to reduce brake overheating and resist corrosion, and high-temperature piston seals for increased durability, controlled retraction, and friction-free operation. Additional features include polished bleed screws and hardware, a unique anti-rattle clip for the pads, and brake pads designed to operate in the widest range of temperatures and environments, using our industry-leading stainless steel rotor-compatible formulation. id="MainContent_lblPistType" class="Gray11B">Stainless Steel
