These Wiseco piston kits are exclusively designed to offer the Harley-Davidson owners many advantages over stock and other aftermarket pistons. The Wiseco pistons are forged design for superior strength over the stock cast pistons yet can be set-up at .0025 to .0035" clearance for quieter operation versus competitors forged pistons who require .005 to .006" clearance. Their weight is approximately 60 grams less than stock factory pistons for quicker revs and less strain on the connecting rods. Kits include two pistons, Hastings X-style rings, wrist pins and circlips.
