Planning on upgrading to a Fire Ring on your 5.9L Cummins? While it's always smart to replace gaskets every time you are upgrading or replacing engine parts, fire rings require special gaskets that allow the ring to bite into it and keep the higher combustion pressure contained. If you are running aftermarket power upgrades and want the best solution to avoid a blown gasket choose fire rings with Industrial Injection!

NOTE: Do not use factory head bolts. Installation of a fire ring gasket requires high yield head studs to ensure proper seat of the head to the cylinder block.

Fire Ring Specs:
