MID-62130
Regular price $324.63In Stock
All 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. This shape combined with a top quality ring package and computerized machined anti-detonation grooves offers you the most technically advanced piston kits available. Wiseco pistons are available with either Hastings X Style or Wiseco XC Style piston rings. All replacement ring sets include rings for one piston only. Must use 63026A when replacing piston pin lock rings in all Wiseco pistons. Hastings X Style rings are not interchangeable with Wiseco XC Style rings. All piston kits listed are designed to be used with stock stroke flywheels only. Most Wiseco 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. All 883cc to 1200cc overbore and 84ci Big Bore kits do not require cylinder head modification or flywheel rebalancing unless deemed necessary by the service technician. The 84ci Big Bore kits require Big Bore cylinders and crankcases must be bored to accept the larger cylinders.Piston Kit.
