Our collection of Pistons for Harley-Davidson engines provides high-quality replacements and performance upgrades for all major engine families. As an authorised Iron City Harley-Davidson dealer, we stock MCS, Eastern and KB Performance pistons for 1957-1971 XL900, 1972-1985 XL1000, 1941-1978 1200cc/74-inch Knucklehead, Panhead and Shovelhead, 1984-1999 1340cc Evolution Big Twin and 1988-2003 XL1200 models. Whether you are performing a stock rebuild, increasing compression for more power or building a stroker motor, our pistons deliver the quality and specifications needed. Cast from high-silicon aluminium alloys, these pistons withstand the heat and stress of Harley-Davidson operation. Available in standard and oversize bore dimensions for precise fitment. Free UK delivery on orders over £100 from our Leeds-based team. Browse the full range below.
