WK1614 1340cc Shovel low compression piston kit. +.010"

This forged Wiseco piston kit is engineered for 1979 to 1984 1340cc Shovelhead engines that require a .010 inch oversize bore. By utilizing a 7:1 compression ratio, which is lower than the factory 8:1, this kit significantly improves engine reliability and reduces the risk of detonation. The forged construction offers superior strength compared to cast alternatives. Each kit includes the pistons, wrist pins, circlips, and a set of Hastings rings. These pistons are designed to accommodate 1.2mm top and middle rings with a 4.75mm oil ring. It is an ideal choice for riders looking to refresh their Shovelhead while ensuring a cooler-running, more durable motor.
