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.

Labrador Retriever Fun Toy

Excellent for older Labrador Retriever with a soft mouth. 2 levels of movements. Colorful. Recharge quickly too, cable included. 2 velcro type covers. Fairly chew resistant, watch your dog, as with any toy! Good size, no worries about my Labrador swallowing it!

Great engaging toy for my border collie
Color: Blue
I have an 8 yr old border collie with an injured rear hock, so she can't chase the Frisbee any longer. This toy, when set on high, kicks her hunting instincts in, and she chases it, brings it back, and keeps it between her paws until it activates *or she bumps it). The plastic 'holey' covering let's her get a good grip on it, and it is a little larger than a baseball. Good quality plastic/soft rubber covering. It charges quickly, and has unpredictable jumps and rolls unlike some others that just run on 1 track. She would play with it all day if I let her. She brings it to me to play with her, but it doesn't really need a human's intervention. A tooth will occasionally hit the small control and turn it off, but no concerns about it falling apart or her ripping it apart. Highly recomment

Not as durable as it could be, but fun
Color: Yellow
Our 55 lb lab has fun with this toy, but it's not lasting long. The ball itself is hard plastic and the yellow rubber wrap around it has already been chewed through n several places. It did come with a fabric cover, but that, too, is not durable. Would not recommend leaving with your dog unattended as they could eat the rubber off in no time. But to bring out occasionally while watching the dog, which is what we do, it does provide some fun for all!

Durable enough for my dog's tough play. She loves this interactive ball.
Color: Blue, Color: Blue
I love these interactive ball toys. My dog gets so excited and engaged with them. I went through 3 of them that my dog destroyed in a short time. They simply were not durable enough for her tough play. So far, we have had this one for a few weeks, it is holding up and withstands her chewing and rough play, and she loves it. It keeps her busy for a long time.

Great toy for old dogs
Color: Yellow
Great to bring a old dog back to his old self. Have a 10 yr old who has a little shoulder pain but needs a little light excitement. This did the trick, he paws it a little and enjoys moving it around. It can take his biteing without breaking. Hopeing our small dog whos afraid of it will watch and get over her fear. She learns everything from him.
