Pistons And Rings Kits

234 products

Our range of pistons and rings kits for Harley-Davidson covers complete matched piston-and-ring assemblies for everything from Knucklehead-era Big Twin to Twin Cam 96" engines. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks piston and ring kits from KB Performance Piston, S&S, Wiseco and MCS — four brands with deep credibility across the Harley-Davidson aftermarket. Coverage includes 1941–1978 74"/1200cc Knucklehead, Panhead and Shovelhead Big Twin, 1979–1984 1340cc Shovelhead, 1984–1999 1340cc Evolution Big Twin, and 2007–2017 96" Twin Cam fitments. Buying a matched piston and ring kit takes the guesswork out of compatibility — the dome design, ring grooves, bore size and ring set are all specified together to work as a unit. Whether you're rebuilding to stock displacement or chasing a specific compression ratio for a hop-up, these kits give you a known, tested combination ready to drop into your cylinder.
