Introducing the newest addition to our family, our XP2 head studs rated at a tensile strength of 260,000 psi will transform your 24V Cummins to an impeccable, unstoppable, and destructive beast.
DIRECT FIT REPLACEMENT - Fits 1998.5-2018 Dodge Cummins 5.9L 6.7L Diesel Cylinder 24V Models. Engineered to unleash more performance out of your vehicle. Centerless ground to assure perfect concentricity. Please see vehicle compatibilities below to ensure accurate fitment.
ULTRA STRENGTH - Rated at 260,000 psi tensile strength, our XP2 material properties allow for far greater tensile strength compared to 8740 chromoly steel head studs. Threads are rolled after heat treatment for optimum fatigue strength. Ample clamping strength prevents cylinder heads from lifting.
EASY INSTALLATION - Broached stud ends install & make cylinder head removal easier. Installation manual is included with drawn diagrams to ease the installation process. Head studs are designed to retain cylinder seal even with today's extreme high pressure turbo systems. These studs far exceed clamping forces provided by standard head bolts.
KIT INCLUDES - 26x Heads Studs, 26x Nuts, 26x Hardened Parallel Washer, 1x Allen Wrench, 1x 14mm Socket, 1x Fastener Assembly Lubricant & Instructions Manual. Black oxide finish protects from wear and tear. Hardened parallel washers allow for uniform load distribution and accurate torque readings.
WORRY-FREE PURCHASE - Xotic Performance is dedicated to offering LIFETIME WARRANTY and full money back guarantee if you aren’t satisfied. Rigorous quality inspections are undertaken to ensure premium product standards.

In 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 dealing with trucks is that when you add parts that increase horsepower (turbocharger, injectors, chips etc.), 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. Xotic Performance head studs are created using premium steel alloys (XP2) that are far superior in tensile strength to a bolt. Our head 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 - so that you never have to deal with the exhaustive procedure of replacing another failed head gasket.
