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.
Features:

  • Includes 12-Point Nuts and Washers
  • Yield Strength: 210,000-230,000 PSI
  • Tensile Strength: 220,000-236,000 PSI
  • Threads Rolled After Heat Treatment
  • Reusable Unlike Torque-To-Yield (TTY) OEM Bolts
  • 10mm Studs Test Out At Max Load Of Over 120KN
  • Manufactured In ISO/TS 16949 Quality Control Facility
  • 8740 Chrome Moly Construction With Added Proprietary Element

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 and 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.

Sturdy, Reliable, and Visually Pleasing - A Must-Have Patio Accessory!
I recently purchased the Best Choice Products 55lb Capacity Fillable Umbrella Base Stand for my backyard patio, and I have to say, I'm absolutely thrilled with this purchase. This umbrella stand has quickly become a reliable and crucial part of our outdoor setup. To start off, the assembly was straightforward and didn't take up much time. The instructions were clear, easy to understand, and within minutes we were able to get it set up. No additional tools or complex steps were necessary, which was a great relief as I'm not exactly a DIY person. I filled it with sand, which brought it to its maximum capacity of 55lbs, and the stability it provides is exceptional. We've had several windy days since I've purchased the stand, and not once has my patio umbrella tilted or tipped. The 2 adjustment knobs on the sides help to secure the umbrella pole firmly, which provides an additional layer of stability. The stand's faux wicker design is another aspect I absolutely love. It beautifully complements my other patio furniture and adds a touch of sophistication to my outdoor decor. The plastic used for the stand is of high quality and convincingly mimics the look of real wicker without the associated maintenance or weathering concerns. Being a round base, it conveniently fits in our patio corner without taking up too much space. Moreover, it's been outside in various weather conditions - from intense sun to rain showers - and it hasn't shown any signs of wear or color fading. The material seems durable and capable of withstanding different weather patterns, which is exactly what I needed. Also, despite being sturdy and heavy when filled, the base is easy to move around when empty. This makes it convenient to store away during the winter or rearrange when we want to change up our patio layout.

Good stand but has issues.
Color: Black - Sunburst
Very sturdy and looks good. But, the part that holds the umbrella is loose and requires a wedge to stop it spinning (I used a plastic knife). Also the screw on the bottom RUSTS and in a BIG way. To solve the rust issue I put an old plastic cutting board under it. We use it with the modifications mentioned.
