KB924C030 Performance, piston set +.030

For 1986 to 2022 Sportster XL883 owners looking to maximize their displacement, this KB Performance forged piston set provides a +.030 inch oversize option for 1200cc conversions. These pistons are designed to function perfectly with stock 883 heads, resulting in a 10.1:1 compression ratio. The 4032 alloy forging ensures high structural integrity and the ability to flex under detonation, providing a long-lasting top end. Sold as a set, this kit includes piston rings, offset wrist pins, and retaining rings. Be aware that 2004 and later XL models require the use of 1200cc cylinders, as the original 883 liners lack the thickness for this overbore. Proper installation is key; ensure the offset pins are oriented correctly to the front and rear of the engine as specified in the instructions.
