Designed For Accurate Fit And Dependable Engine Performance

Industrial Injection developed the X-Series .020 Piston Kit to provide a direct replacement solution for 1998.5-2002 5.9L Cummins 24V 6BT engines that require a .020 inch oversize piston. Each matched piston set is manufactured to deliver consistent fitment across all cylinders, helping support balanced engine operation after a proper rebuild. Furthermore, the included rings, wrist pins, and retaining clips eliminate the need to source essential installation components separately. The low friction anti scuff skirt coating helps minimize piston skirt wear while reducing friction against the cylinder walls throughout normal engine operation. This version retains the factory compression height, making it well suited for OEM style engine configurations that do not require additional valve clearance or specialized piston designs. Because this is an oversize piston kit, it should only be used after confirming the engine block has been machined to accept a .020 inch oversize piston. Always verify bore dimensions during the rebuilding process to ensure proper piston to cylinder clearance and long term engine reliability.
