One New Aftermarket Replacement Standard Piston Kit Fits Case / Fits Case IH and Fits International Harvester Equipment
This standard bore (STD) piston kit is a direct replacement for the Cummins 4B/4BT/6B/6BT series diesel engine found across a wide range of Fits Case, Fits Case IH, and Fits International Harvester construction, agricultural, and industrial equipment. The kit restores combustion sealing and compression in worn engines, addressing loss of power, hard starting, and excessive oil consumption. Each kit includes pistons, piston rings, wrist pins, and retaining clips (pin retainers) for a complete rebuild-ready assembly.
