Product Description
CUMMINS 4955212 OEM EXHAUST VALVE KIT – RAM 6.7L (2007.5–2018)
The genuine CUMMINS 4955212 OEM exhaust valve kit is the factory-engineered replacement for 2007.5–2018 6.7L Cummins ISB engines. Exhaust valves operate under extreme heat and pressure, and worn or burned valves can cause loss of compression, poor performance, misfires, or turbo efficiency issues. Installing a true Cummins OEM valve kit ensures proper heat resistance, metallurgy, sealing, and long-term durability that aftermarket copies simply cannot match.
This kit includes the correctly machined, hardened exhaust valve required to restore precise exhaust sealing, combustion efficiency, and turbocharger performance. Whether you're rebuilding a high-mileage 6.7L, repairing a dropped valve, or addressing cylinder head wear, this OE-spec valve kit is the right choice for reliability and long-term service life.

Frequently Asked Questions
WILL THIS EXHAUST VALVE FIT MY 6.7L CUMMINS?
Yes. CUMMINS 4955212 fits most ISB 6.7L engines from 2007.5–2018. Always confirm by VIN/ESN before ordering.
SHOULD I REPLACE ALL EXHAUST VALVES AT THE SAME TIME?
It is highly recommended. Valves wear together, and replacing a single valve may not resolve sealing or compression issues.
WHAT OTHER PARTS SHOULD BE REPLACED DURING A VALVE JOB?
Most technicians replace valve stem seals, locks, and inspect guides and seats.
IS THIS A GENUINE CUMMINS PART?
Yes — CPP Diesel supplies only factory-original Cummins components for maximum durability and correct fitment.
