The kit replaces OEM #3164780 \/ PN 4965569 with heavy-duty carbon-steel pieces that guide seals to the correct depth and provide a controlled, repeatable removal method. That combination of fitment accuracy and durable construction reduces downtime and lowers the risk of costly surface damage during maintenance.\n\n\u003ch3\u003eWill this kit fit my Cummins ISX or QSX engine?\u003c\/h3\u003e\n\u003cp\u003eYes — the tools are machined to match the dimensions used on Cummins Signature, ISX, QSX, including ISX12 and ISX15 families and the latest-style rear main seals.
