FAQ
Is this Cummins 3929734 camshaft the correct OEM cam for the 12-Valve P-pump engine?
Yes. This is the factory camshaft used in 1994–1998 5.9L 12-Valve Cummins engines equipped with the P7100 injection pump.
Can this camshaft be used in a 1989–1993 12-Valve engine?
Some early 6BT engines use a different Cummins camshaft profile and part number. ESN verification is recommended before using this cam in pre-1994 models.
Does this camshaft require new tappets or lifters?
It is strongly recommended to install new tappets when replacing a camshaft to ensure proper break-in and longevity.
Is this camshaft suitable for performance upgrades?
While strong and durable, this cam has a factory OEM profile. Performance cams require more lift/duration and should be sourced from performance manufacturers.
