Descriptions and notes
KB pistons can be installed tighter than other pistons. This results in less piston rock and better ring seal. Please read instructions included with piston for correct piston clearance. Due to the thermal conductivity and design of KB pistons, special attention is required to the top ring end gap. Please read instructions furnished with piston for correct ring installation. Each replacement ring PART # denotes rings for two pistons, except 48-99 Big Bore kits and 99-06 88” Twin Cam kits, which require two sets.
Must use KB lock rings.
