About this part

Product Details

If you're working on the top end of your 2019 or newer Ram 2500 or 3500 with the 6.7L ISB Cummins engine, this Cometic MLX head gasket is built to seal things up tight. This gasket is specifically made for a 4.327-inch bore and has a thickness of .054 inches, ensuring it works correctly with your engine's specifications.

Cometic's MLX (Multi-Layer Stopper) technology uses an integrated stopper layer. This layer helps seal the combustion chamber and increases the clamping force around the cylinder without causing distortion. It's constructed using the same materials as their popular MLS head gaskets, and the outer layers are coated with Viton for added sealing performance. You won't need to use any extra sealants or re-torque the head after installation with this gasket.
