Upgrading the factory head bolts is a must when start adding horsepower and torque to your Silverado\/Sierra. The factory bolts typically can't handle the additional pressure in high-performance applications which can lead to the cylinder heads lifting. Upgrading to the XDP head studs helps to keep the cylinder heads locked down and avoid potential head gasket failures. Constructed using an 8740 Chromoly Steel with an added proprietary element ensures these studs are stronger and will not stretch like the stock bolts. The threads are rolled after heat-treating to deliver maximum fatigue strength. These studs are rated at 205,000+ psi yield strength and 225,000+ psi tensile strength to ensure a strong hold under higher combustion pressures.\u003c\/p\u003e\n\u003cp\u003eIn addition to the increased strength, replacing the head bolts with studs also allows you to obtain a more accurate torque reading. A conventional bolt gets twisted as it is tightened, so it's reacting to two different forces at the same time. With a stud the force gets applied to the vertical axis, resulting in a more even clamping force. Another benefit of studs is they allow for easier engine assembly and proper alignment of the cylinder heads every time. These are a must-have for high-performance applications and are reusable, unlike the OEM Torque-To-Yield (TTY) bolts which must be replaced after each use. The studs are manufactured in an ISO\/TS 16949 quality control facility. Included with the studs are washers and 12-point nuts.
