Cummins 4955354 6.7L ISB Upper Engine Head Gasket Kit

6.7L Cummins 4955354 OEM Upper Engine Head Gasket Kit

This is a brand new complete upper engine head gasket kit manufactured by Cummins. The 4955354 gasket set is required to successfully replace the blown head gasket on your Cummins 6.7L ISB. If you own a Cummins 6.7L and you're having issues with a loss of heat or high engine coolant temperatures, then it may be time to replace your head gasket. The Cummins 6.7L diesel engine has a unique problem that many owners with increased power levels are now dealing with. 

Why is the head gasket failing on the Cummins 6.7L Diesels?

The 6.7L has a longer stroke and a quick-spooling VGT variable geometry turbocharger which produces increased cylinder pressure at low engine RPMs. The Cummins 6.7L also features an increased bore diameter which means less head gasket material between the cylinders and the coolant jackets. Combine these factors with increased power output level and you start to see why head gasket failure is so common on 2007.5 to 2020 Dodge Ram trucks with the Cummins 6.7L diesel.

If you own a Cummins 6.7L and you are having any of the following issues it's now time to look at this Cummins 6.7L upper engine rebuild kit to solve these conditions:

• Issues with loss of heat
• High engine coolant temperatures.
• Sounds of air bubbles are traveling through the dashboard.
• Dramatic engine temperature fluctuations.
  
• Loss of compression in select cylinders
