There is a Mid-Year split on the head bolts, if you have 2 different size head bolts this kit is NOT for YOU.. ULTRA STRENGTH In comparison to standard bolts, our alloy's material characteristics enable much higher tensile strength. For the best fatigue strength, threads are rolled after thermal treatment. A high-quality coating can improve corrosion resistance, reduce friction, and improve overall performance.. Premium Quality The black oxide coating guards against deterioration.  Parallel washers that have been hardened enable precise torque measurements and uniform load distribution.. Easy Installation The XP981 kit also features a high-temperature coating that provides enhanced heat resistance. This helps to prevent the studs and nuts from becoming damaged or weakened due to high temperatures, which is especially important in high-performance diesel engines.. Torque capacity The bolts have the appropriate torque capacity to handle the high compression and cylinder pressures of these engines. Please note, when installing our product, the final torque for the 11mm bolts are 75 ft-lbs and NOT 85 ft-lbs as incorrectly noted on our manual..
