A limited number of KB pistons have the ring grooves crossing the piston pin hole. In order to have the piston rings properly supported these pistons come with piston ring support rings. As support rings do not have a sealing function they do not have to be replaced when you install new piston rings, but sometimes new ones are needed because a ring is lost or broken.
Fits KB264 and KB272 series pistons for 1200 Evolution Sportster and XL883 to 1200CC conversions, For standard thru +.020" bore
