      Head Studs Vs. Head Bolts

      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 (XOTIC 7200) 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.

       

      INDESTRUCTIBLE TENSILE STRENGTH

      XOTIC 7200 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. Premium quality inspection standards ensure you'll never get a blow head gasket again.

              



      OPTIMUM DESIGN

      Broached stud ends install & make cylinder head removal easier. Engineered to unleash more performance out of your vehicle. Ample clamping strength prevents cylinder heads from lifting. 

          



      ULTRA CLAMPING FORCE

      Head studs are designed to retain cylinder seal even with today's extremely high-pressure turbo systems. These studs far exceed clamping forces provided by standard Ford head bolts.

       

      NUTS & WASHERS INCLUDED

      Black oxide finish protects from wear and tear. Hardened parallel washers allow for uniform load distribution and accurate torque readings.

       

      INSTRUCTIONS INCLUDED WITH DRAWN DIAGRAMS

       

      All details including torque recommendations are included in the manual for your reference.
