Description

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 225,000+ psi tensile strength and 205,000+ yield strength to keep your cylinder heads from lifting under higher combustion pressures. Assembly lubricant sold separately.

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 & 12 Point Nuts
  • Yield Strength 205K psi - 215K psi
  • Tensile Strength 225K psi - 233K psi
  • Will Not Stretch Like The Factory Studs
  • Thread Has Been Rolled After Heat Treatment
  • High-Strength 8740 Chromoly Steel 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


TECH TIPS:
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.

XDP X-TRA Slick Engine & 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.
