FAQ
Will this fit my 2003–2007 5.9L Cummins?
Yes, this gasket fits Ram 2500/3500 trucks equipped with the 5.9L 24-valve Cummins for model years 2003–2007.
Does the set include bolts or RTV?
No—this listing is for the oil pan gasket only. Reuse hardware if serviceable or replace as needed. Follow Cummins service recommendations for any RTV at joints/corners.
Should I replace pickup tube seals at the same time?
It’s good practice to inspect and replace the oil pickup/suction tube O-rings and related seals during service to prevent aeration or future leaks.
Any installation tips?
Clean mating surfaces thoroughly and torque oil pan fasteners in sequence to factory spec. Verify pan flatness before installation for best sealing.
