KB924C010 Performance, piston set +.010

Engineered for the 1986 to 2022 Sportster XL883, this KB Performance forged piston set allows for a reliable 1200cc conversion using +.010 inch oversize pistons. These pistons are designed to work with stock, unmodified 883 heads and provide a 10.1:1 compression ratio. The 4032 aluminum alloy construction offers superior molecular strength compared to cast alternatives, allowing the piston to withstand pre-ignition stresses. Sold as a set, the kit comes complete with piston rings, wrist pins, and retaining rings. For 2004 and newer models, please ensure you are using 1200cc cylinders as the original 883 liners are not suitable for boring. Due to the offset wrist pin design, correct front and rear orientation is required during installation to ensure optimal performance and reduced engine noise.
