Our Piston & Ring Kits range for Harley-Davidson is the place to start when planning a top end rebuild or big bore upgrade on a Harley-Davidson. Supplied through Iron City Motorcycles, an Iron City authorised HD dealer in Leeds, this section covers Sportster, Dyna, Softail and Touring engines with a focus on matched sets that include forged pistons, rings, wrist pins and clips. Expect premium-quality kits from S&S, engineered with the ring land strength and piston crown profiles needed to stand up to strong torque figures on Evolution, Twin Cam and Milwaukee-Eight Harley-Davidson engines. Standard and oversized pistons are available for bore clean-ups, with a range of compression ratios to suit everything from a mild service refresh through to a performance build. Pair with quality head gaskets and torque to spec. Browse the full range below.
