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.

Almost Indestructible!
Size: Medium Set of 6
My dog LOVES these balls, and it's all about the squeaker (which my husband hates). The size is great and I don't worry about it getting lodged in her throat. They are very durable too. We had one lone ball for YEARS and I forgot it ever squeaked, but it was still in tact. I searched for a replacement because I was so impressed with it. Very happy to have found it. I just ordered some for my son's dog too. The squeaker may eventually come loose, but it's worth the money to buy again!

The most durable and fun dog toy of all
Size: Medium Set of 6
Most durable and fun toy of all. The only thing that I have found that can destroy these balls is a lawnmower. Probably good for keeping teeth clean too.

loud but in a good way
Size: 4.5"
Love these crazy loud squeeky balls. I bought two a bit too big but the dogs still love them. Yes, they will drive you insane but the dogs love them so much it's worth it watching the pups enjoy the balls. They are strong and safe as long as they aren't too small for your dogs mouth.

Great for aggressive chewers - Great for clean teeth
I never thought these would stand up to my 60lb pittie puppy's chewing. But they are far and away her favorite toy and are holding up beautifully. One squeaker insert bit the dust -- which is not bad since it gives us one silent one. But otherwise they are holding up superbly to her powerful jaws. We have tried a lot of toys. So far, all the "for aggressive chewers" toys have been torn apart within days if we are lucky -- usually it's minutes. But these balls show little-to-no sign of wear. The squeakers are very loud which she loves can get a bit tiresome. So, as I mentioned, having one silent one is a great option. And she really likes the texture. She loves them so much, we bought a second set and will probably buy a third to have in reserve. (We are realistic and don't expect them to last forever.) All I have to say is "where's spiky ball" and she instantly stops what she is doing and goes on the hunt. A great buy!! (NOTE: It's been almost three months and one is just beginning to show some damage. Given that she plays with them non-stop, they've showed amazing durability. And everyone comments on how clean and beautiful her teeth are. I don't brush them or give her dental treats. So it has to be these balls!!)
