The modern alloys used in these pistons, coupled with the advanced skirt profiles, allow them to be fit tighter resulting in low engine noise and long engine life
These pistons are normally used in stock HD® cylinders, and must be purchased separately, based on the required piston oversize
Please review manufacturer details to ensure proper fitment before ordering.
