    NOTE: KB pistons can be installed tighter than other pistons. This results in less piston rock and better ring seal. Please read instructions furnished with piston for correct piston clearance.

    NOTE: 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.

    Our pistons, rings and kits are sold by application and bore size. Please note that STANDARD and OVERSIZES are not indicated. To get the correct part, you must know the standard bore size to make sure you are ordering either the standard or correct amount of oversize that you need.
