FAQ

WILL THIS FIT MY 5.9L OR 6.7L 24-VALVE CUMMINS?

Yes—coverage spans 1998.5–2007 5.9L (VP44 & common-rail) and 2007.5–2018 6.7L ISB. For late-model 6.7L, confirm by VIN/ESN.

HOW MANY DO I NEED?

There are 12 intake valves in the 24-valve head. Order 12 if replacing all intake valves (exhaust valves are separate parts).

WHAT’S INCLUDED IN THE KIT?

One intake valve (3940735) and keepers/collet. Some listings bundle the seal; if not, add valve stem seals separately.

IS THIS A GENUINE CUMMINS PART?

Yes—3802924 is a genuine Cummins intake valve kit used across ISB/QSB applications.

CAN I MIX WITH AFTERMARKET VALVES?

Best practice is to keep a matched set per bank for even wear. If mixing, match dimensions/materials and always set lash.
