Description

Wiseco pistons kit, flat top 9:1 compression .020″ oversize for Harley Davidson Sportster 1200cc. Wiseco Pistons are forged from hi-silicon aluminum alloy for superior strength and dependability. The unique piston shape allows tight piston to wall clearances for quieter operation. Grooves are machined around the top ring lands to reduce detonation and improve the sealing power of the top ring. Pistons are machined with valve pockets that are deeper and larger than stock. These pockets provide adequate valve clearance for most high lift cams, but as with any high performance upgrade all clearances must be checked.
