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.

⭐⭐⭐⭐⭐ Great for teething puppies
Size: Small, Color: Pink
I purchased the Nylabone puppy chew toys for my teething puppy, and they’ve been a big help. The toys are the perfect size for a young puppy and feel durable without being too hard. My puppy enjoys chewing on them, and they’ve helped redirect chewing away from furniture and shoes. I also like that they’re designed specifically for puppies, so they’re gentle enough for growing teeth and gums. The variety in the set keeps my puppy interested, and the toys have held up well with daily use. They’re easy to clean and feel safe to give to a puppy. Overall, these are great chew toys for puppies. They’re effective, well made, and helpful during the teething stage. I would definitely recommend them to new puppy owners.

Great Variety for Teething Puppies, Keeps Him Busy!
Color: 9 Pack (No-stuffed Fox), Color: 9 Pack (No-stuffed Fox)
I got this 9-pack toy set for my 11 lb chihuahua-terrier mix puppy, and it’s been very well received by my little guy. He’s been bored being in quarantine until his vaccines kick in and he's also teething. This toy set has made a huge difference. Great variety - you get a combination of rope toys, plush squeaky toys, and even a treat ball, so he often rotates between them depending on what he wants. The rope toys have been especially good for teething, while the softer toys keep him entertained. One of the plush toys has that crinkly texture inside, which he loves. The treat ball is a nice bonus too. I've put treats and his dog kibble in there throughout the day, and it helps keep him engaged and also mentally tires him out. Everything is sized well for a small puppy and light enough for him to carry around easily. The materials feel decent for the price, especially considering how many toys you get. That said, I do keep an eye on him with the softer ones since he’s still a puppy and likes to chew. Pros: Good mix of rope, plush, and interactive toys Great for teething and keeping him occupied Treat ball adds a mental challenge Good size for small dogs/puppies Nice value for the number of toys Cons: Softer toys may wear down faster with heavier chewing Overall, this has been a really useful set during a phase where he’s both teething and needs a lot of mental stimulation. I’d recommend it for small dogs or puppies, especially if you want a variety instead of buying individual toys.

Perfect Puppy Starter Toy Set
Color: 9 Pack (No-stuffed Fox), Color: 9 Pack (No-stuffed Fox)
This toy pack is such a great value for puppies. My puppy stayed entertained for hours and loved having different textures to chew and play with. The toys feel soft but still durable enough for everyday use. A few of the smaller toys are better for light chewing, but overall it’s a fun variety pack for keeping a puppy happy and active.
