GP310 Motorcycle Front (2008-UP)

Wilwood's GP310 motorcycle disc brake caliper has been designed and engineered for use on 2008 to Present Harley-Davidson® Motorcycles. Built around a 4-piston, high performance powerhouse, this billet aluminum caliper brings distinctive, bolt-on styling: Direct leg-mounted calipers are available for all single and dual disc models

The GP310 caliper is available in polished, brilliant chrome or black 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.
