Head Stud Replacement Kit Fits for Ford 6.7L 2011-2019 Powerstroke Models-220000 Psi

Head studs vs BoltsIn every diesel car, there are high cylinder pressures that can damage head gaskets. Factory OEM head bolts are torque to yield, meaning you torque the bolt to a specific torque with a final 90 degree rotation that will place the bolt at its’ maximum stretch point.Our observation through years of inspecting and repairing diesel trucks is that when you add parts that increase horsepower, you risk creating higher cylinder pressures lower than your RPM range, consequently leading to a blown head gasket.In contrast to head bolts, head studs are engineered to not stretch. Head studs are created using premium steel alloys that are superior in tensile strength to a bolt. Our studs are threaded on top to allow for nut placement which will result in a more accurate torque of the head.Rather than blowing your head gasket again, we highly recommend replacing your head gaskets with fasteners that have a proven track record of not stretching.Specifications:TENSILE STRENGTH：220000 psi.PACKAGE CONTENTS: 45x Heads Studs, 45x Nuts, 45x Hardened Parallel Washer, 2x Sockets, 2x Allen Wrench, 1x Fastener Assembly Lubricant, Instructions Manual.FITMENTS: Fits Ford 2011-2019 6.7L Powerstroke.FINISH: Black oxide.STYLE: 12-point.Installation：Use a thread sealer to lubricate block threads of the head studs,only applies if the cylinder head studs extend into the water jacket.Screw studs as tight as can be made finger tight, and install cylinder head.Using THE FASTENER ASSEMBLY LUBRICANT included in the package, lubricate the head studs,ensure nuts and washers are lubricated as well.Install the lubricated nuts and washer onto the head stud as tight as can be made finger tight .Using the torque recommendations in the manual, tighten the cylinder head bolts in 3 equal steps.
