Quick Ship SKU #: PPE-118034700 PPE Head Stud Kit 17-22 GM 6.6L L5P Duramax

Adding more power to your L5P Duramax? Want to increase your durability and be more reliable? Already opening up the top end of your engine? Head studs are a no brainer to help with all of those situations. Head studs are an absolute must especially when upgrading your turbo. The factory head bolts have essentially one pressure point at the head of the bolt, whereas head studs create two points of pressure creating a much stonger hold on the head.

These head studs have been tested and verified to have a tensile strength of over 231,900 psi and are strongly recommended for boost levels 45 psi and higher. Each kit comes complete with hardened parallel washers, nuts, and specially formulated assembly grease for uniform load distribution and accurate torque readings.
