About This Product
This KB Performance piston kit is designed as a standard replacement for 1986 to 2022 Harley-Davidson Sportster XL883 models. Sold as a set and oversized by .030 inches, these pistons feature a flat-top design that maintains the stock 9.0:1 compression ratio. Built from T6 heat-treated 390 hypereutectic aluminum with 16% silicone, they offer the benefit of running very tight clearances for a quiet engine and exceptional longevity. Mechanics must ensure that the top compression ring is gapped with the additional clearance required by KB Performance. This kit provides a durable and quiet solution for refreshing any 883 Sportster top end.
Manufacturer part number: KB408C030.
