Description

XDP X220 Series Head Stud Kit XD3006HSThe XDP X220 Series Head Stud Kit XD3006HS is a must have for your high performance 2001 2016 GM 6. 6L Duramax LB7 LLY LBZ LMM LML. The OEM head bolts typically can't handle the pressure from high horsepower applications. Constructed using 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.

The XDP X220 Series Head Stud Kit XD3006HS is a must have for your high performance 2001-2016 GM 6.6L Duramax LB7/LLY/LBZ/LMM/LML. The OEM head bolts typically can't handle the pressure from high-horsepower applications.

Constructed using 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 220,000 plus psi tensile strength and 210,000 plus yield strength to keep your cylinder heads from lifting under higher combustion pressures.

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 which allows you to obtain a more accurate torque reading.

These studs are a must-have for high-horsepower applications and are reusable, unlike the OEM Torque-To-Yield (TTY) bolts which must be replaced after each use. Another benefit of studs is they provide for easier engine assembly and proper alignment of the cylinder heads every time.

These studs are manufactured in an ISO/TS 16949 quality control facility. Includes installation instructions for a hassle-free installation.

Features:

  • Includes Washers and 12 Point Nuts
  • Yield Strength 210K psi - 230K psi
  • Tensile Strength 220K psi - 236K psi
  • Will Not Stretch Like The Factory Studs
  • Thread Has Been Rolled After Heat Treatment
  • High-Strength 8740 Chrome Moly Construction
  • 10mm Studs Test Out At A Max Load: Over 120KN
  • Manufactured In An ISO/TS 16949 Quality Control Factory
  • Reusable Compared To Torque-To-Yield (TTY) Bolts Which Are One Time Use Only

XDP Thread Cleaning Chasers (Sold Separately):
The XD40124TC and XD40128TC 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.

So much sturdy fun for little dogs!
Size: Small 2"
Wow! My puppy loves these! He is entertained endlessly chasing after and nose scooting the little rubber balls! He really seems to enjoy the jingle sound and loves to chew on the balls also. Even with a lot of chewing from his little teeth, there are no marks. Sturdy, great toy!

Well made, perfect size!
Size: Small 2"
My dogs love these balls. They are the perfect size and hold up well for my 2 dogs, 7# and 9#. The bell is a nice change from the squeaky toys.

Durable, bouncy, not annoying like squeaky ball & our dogs LOVE them.
Size: Small 2"
Love these and my dogs love them to! Not nearly as noisy as a squeaky ball (thank goodness) and they bounce which are dogs love. They will fetch them, and they will play by tossing it up and pouncing on it when it bounces. They literally entertain themselves with it when we aren't playing fetch. Much more durable than the round rubber / latex squeaky ball / toys.

Quality item.
Size: Small 2"
These seem to be quality dog toys. I bought them for a friend's chihuahua. My cats were unimpressed, lol. The chihuahua had never seen a ball. He seemed curious, but would not approach this new item. Time will tell. The bells have a very loud shrill sound, completely unlike any I've ever heard before.

What I was looking for!
Size: Large 3"
I bought these to continue playing fetch with my blind dog, she loves it! The only downside is the bell has slipped out once in a great while, but is easily reinserted.
