XDP XD3008MS MAIN STUD KIT FOR 06-10 GM 2500/3500HD WITH DURAMAX ENGINE

Upgrade the factory main bolts in your 2006-2010 GM 6.6L Duramax LBZ/LMM with the XDP X220 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 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 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.

Tech Tips:
XDP Thread Cleaning Chasers (Sold Separately):
Both the XD40126TC and XD40125TC are a great add-on that will be critical during installation. Thread Cleaning Chasers are an excellent tool to have on-hand to ensure you have properly cleaned the threads in your engine block before the installation of any fasteners. Clean threads provide accurate torque readings and will help give you peace of mind during your engine build.

XDP X-TRA Slick Engine & Fastener Assembly Lubricant (Sold Separately):
The use of XD541 is highly recommended during engine assembly. Apply XDP X-TRA Slick Lubricant to head studs, head bolts, main studs, main bolts, connecting rod bolts, and any other fasteners used during engine assembly. Using a proper assembly lubricant during fastener installation reduces friction and torque pre-load scatter in the torquing sequence, while also helping to prevent thread galling and seizing.

The XDP XD3008MS Main Stud Kit is the perfect enhancement for GM 2500/3500HD trucks equipped with the robust 6.6L Duramax LBZ/LMM engine from 2006 to 2010. Designed specifically for high-performance applications, this kit replaces the factory main bolts with superior-grade main studs, ensuring your engine can withstand the rigors of high horsepower and torque.

Crafted from 8740 Chromoly steel with a proprietary blend for added strength, these studs are engineered to eliminate the stretch common with OEM bolts, providing you with a reliable hold under extreme combustion pressures. Featuring an impressive tensile strength rating of 220,000-236,000 PSI and a yield strength of 210,000-230,000 PSI, the XDP Main Stud Kit caters to the demands of serious automotive enthusiasts.

One of the most significant advantages of using studs over conventional bolts is the improved torque accuracy. Unlike bolts that twist during tightening, the design of these studs allows for a direct vertical force, resulting in more consistent clamping pressure across the main bearing caps. This not only ensures optimal engine performance but also simplifies engine assembly and proper alignment.

The kit includes all essential components: main studs, 12-point nuts, and washers, accompanied by clear installation instructions. Notably, these reusable studs are a cost-effective alternative to Torque-To-Yield (TTY) OEM bolts, which require replacement after each use.

To achieve the best results, consider pairing your installation with XDP Thread Cleaning Chasers and XDP X-TRA Slick Engine & Fastener Assembly Lubricant, both sold separately. These tools enhance installation precision and mitigate common issues associated with fastener assembly, ensuring your engine performs at its peak potential. Elevate your Duramax build today with the XDP XD3008MS Main Stud Kit.

The XDP XD3008MS Main Stud Kit is an essential upgrade for 2006-2010 GM 2500/3500HD trucks outfitted with the powerful 6.6L Duramax LBZ/LMM engine. Designed to meet the demands of high-performance applications, this kit replaces stock main bolts with enhanced main studs that provide unmatched durability and strength.

Constructed from top-grade 8740 Chromoly steel, each stud features a proprietary blend that minimizes stretching, a common issue with OEM bolts under high combustion pressures. With an impressive tensile strength rated between 220,000-236,000 PSI and yield strength between 210,000-230,000 PSI, the XDP Main Stud Kit ensures your engine can handle extreme power and torque with ease.

One of the major benefits of switching to studs is the improved torque accuracy. Unlike conventional bolts that twist during tightening, the straight design of these studs allows for a consistent vertical force application. This results in an even clamping pressure across the main bearing caps, promoting optimal engine performance and facilitating a smoother assembly process.

The kit comes complete with main studs, 12-point nuts, and washers, all accompanied by straightforward installation instructions. Additionally, the reusability of these high-strength studs makes them a cost-effective alternative to traditional Torque-To-Yield (TTY) OEM bolts, which must be replaced after each use.

To enhance your installation experience, consider adding the XDP Thread Cleaning Chasers and the XDP X-TRA Slick Engine & Fastener Assembly Lubricant, both sold separately. These tools will ensure clean threads and reduce friction during assembly, promoting the integrity of your engine build. Elevate your Duramax performance with the reliable and robust XDP XD3008MS Main Stud Kit, engineered for automotive enthusiasts seeking uncompromising power and reliability.
