Selling Out Xdp X220 Series Head Stud Kit Xd3006hs Fast Dispatch [6HRBZLO1]

The Selling Out Xdp X220 Series Head Stud Kit Xd3006hs Fast Dispatch [6HRBZLO1] 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.

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.
