Main Stud Kit 2006-2010 GM 6.6L Duramax LBZ/LMM XDP Xtreme Diesel Performance

Whether you are setting up your Duramax for the track or street, upgrading the stock OEM main bolts is a must. The factory bolts typically can't handle the pressure found in high-horsepower applications. Constructed using an 8740 Chromoly with an added proprietary element ensures these studs will not stretch like the factory bolts. The threads are rolled after heat-treating to deliver maximum fatigue strength. These studs are rated at 220,000-236,000 psi tensile strength and 210,000-230,000 yield strength to ensure a strong hold under higher combustion pressures. In addition to the upgraded strength, replacing the main 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
