Product Description
CUMMINS 3802967 OEM EXHAUST VALVE KIT – RAM 5.9L (1998.5–2004)
The genuine CUMMINS 3802967 OEM exhaust valve kit restores proper cylinder sealing, exhaust flow, and valve timing integrity on 1998.5–2004 5.9L ISB engines. Exhaust valves live in the harshest thermal conditions in the Cummins cylinder head, and worn or burned valves can lead to loss of compression, misfires, excessive smoke, and power loss. This kit provides the exact OEM-spec exhaust valve components engineered to handle high EGT, long-duty cycles, and the heat load common in towing and performance environments.
Designed for 24-valve ISB heads, this Cummins exhaust valve kit ensures proper valve face geometry, stem diameter, metallurgy, and length for reliable operation and OE-level durability. Whether you're performing a cylinder head rebuild, repairing a dropped valve, or refreshing a high-mileage engine, this is the correct OEM-grade replacement for long-term reliability.

Frequently Asked Questions
WILL THIS EXHAUST VALVE KIT FIT MY 1998.5–2004 24-VALVE CUMMINS?
Yes. This kit is used on all 5.9L ISB 24-valve engines from 1998.5–2004. Always verify by ESN for head variations.
SHOULD I REPLACE INTAKE VALVES AT THE SAME TIME?
Yes. Most cylinder head rebuilds include both intake and exhaust valves. You can use the CUMMINS 3947412 intake valve for proper pairing.
DOES THIS KIT INCLUDE VALVE STEM SEALS?
No—seals are sold separately. We recommend replacing them with CUMMINS 3942582 valve stem seals.
CAN WORN EXHAUST VALVES CAUSE SMOKE OR HARD STARTING?
Yes. Burned or leaking exhaust valves dramatically reduce compression, which leads to smoke, rough idle, or hard starting.
IS THIS A GENUINE CUMMINS PART?
Absolutely. CPP Diesel supplies only authentic Cummins OEM components for engine rebuilds.
