06-10 GM 6.6L Duramax LBZ/LMM XDP Main Stud Kit

Fits: 2006-2010 GM 6.6L Duramax LBZ/LMM

Upgrade the factory main bolts in your 2006-2010 GM 6.6L Duramax LBZ/LMM with the XDP Main Stud Kit XD3008MS. 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 Chrome Moly 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 more even clamping force. In addition, they typically allow for easier engine assembly and proper alignment of the main bearing caps 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. This kit includes main studs, 12-point nuts, washers, and installation instructions. Assembly lubricant sold separately.
