If you're pushing more power out of your 5.9L or 6.7L Cummins, upgrading your turbo, or just want rock solid reliability, a PPE Head Stud Kit is a gotta-have-it.
Factory head bolts only apply pressure at a single point, but head studs lock everything down with two points of pressure, giving your engine a much stronger hold and preventing head gasket failures under high boost. These head studs have been tested and verified to handle an incredible 231,900 PSI of tensile strength, making them ideal for any build running 45+ PSI of boost. Each kit includes hardened parallel washers, high strength nuts, and specially formulated assembly grease to ensure even load distribution and precise torque readings. For extreme high boost builds, the PPE High Yield Head Stud Kit takes it to another level. With an obscene tensile strength of over 288,000 PSI and a yield strength exceeding 254,000 PSI, these studs outperform anything else on the market.
Regardless of whether you're daily driving, towing heavy, or running a full-blown race setup, PPE head studs give your Cummins the durability it needs to handle serious power with confidence.
