FAQ

Will these bolts fit both 5.9L and 6.7L Cummins engines?

Yes. They’re intended for 1989–2018 Dodge Ram applications using the Cummins 3900630 turbo oil drain flange hardware (two bolts). Always verify your specific drain flange uses this style.

How many bolts come in the set?

Two (2) bolts are included to mount the turbo oil drain flange.

Do I need new gaskets or O-rings?

It’s smart to inspect and replace the turbo drain O-ring/gasket during service. Pair with the CPP -10AN block fitting or a fresh drain gasket as needed for a leak-free install.

Torque specs?

Use factory-equivalent torque values for your year/engine and flange style. If unavailable, tighten to typical M8 flange bolt specs and verify with the service manual.
