The XDP Main Stud Kit XD3007MS is essential for setting up your 2001-2005 GM 6.6L Duramax LB7/LLY for competition or street use. OEM main bolts typically struggle to handle the pressure in high-horsepower engines.

Constructed using an 8740 Chrome Moly with an added proprietary element ensures these studs are more durable and will not stretch like the factory bolts. The threads are rolled after heat-treating to deliver optimum fatigue strength.

These studs are rated at 210,000-230,000 psi yield strength and 220,000-236,000 psi tensile strength to ensure a strong hold under higher combustion pressures.

In addition to the increased strength, replacing the main bolts with studs also allows you to obtain a more precise torque reading. A 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. 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.

Furthermore, they can help offer easier engine assembly and proper alignment of the main bearing caps every time. These studs are manufactured in an ISO/TS 16949 quality control facility. Included in this kit are 12-point nuts, washers, 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 Studs, Unlike 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 XD40125T 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 or head gasket repair.

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.

Nice brackets
These are nice sturdy brackets for butcher block shelf however they do bend a bit. We installed in a corner so was able to pin to side wall no problems on big shelf. The smaller shelf about 18” moves a bit up and down when loading. Now very little and no worries about it but not rock solid

Sturdy Shelf Brackets
I really like these shelf brackets. They seem very sturdy, which is great for my laundry room shelves over the washer & dryer pair. It's going to be great to FINALLY have shelves for laundry supplies or "buyers' club" household items like 12-packs of paper towels or 36-packs of T.P. I can hardly wait to have my sons install them so I can fill them up!

Neat and Square
Color: Black, Size: Square
This turned out to be durable and looks good on my valet table. The difference in the way it snaps to the sides, keeps the corners square and looks better than the other models that force the corners to extend outward.
