The XDP Main Stud Kit XD3007MS is essential for setting up your 2001-2005 GM 6.6L Duramax LB7/LLY for competition or street use. OEM main bolts typically struggle to handle the pressure in high-horsepower engines.

Constructed using an 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 210,000-230,000 psi yield strength and 220,000-236,000 psi tensile strength to ensure a strong hold under higher combustion pressures.

In addition to the increased strength, replacing the main bolts with studs also allows you to obtain a more precise torque reading. A 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. 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.

Furthermore, they can help offer easier engine assembly and proper alignment of the main bearing caps every time. These studs are manufactured in an ISO/TS 16949 quality control facility. Included in this kit are 12-point nuts, washers, 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

  • Reusable Studs, Unlike 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 XD40125T 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 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.

Good to have if you've never seen the iTEP exam, but don't rely on it to boost your scores
Format: Paperback
This book is good in that it comes with two practice tests: one in the beginning of the book, one in the end of the book. The grading rubric is helpful too. However, the actual guide part of the book, doesn't help too much with how to improve test scores. What I like least about this guide is that it won't tell you which questions you answered incorrectly on the practice exams. A good test prep guide will tell you what you answered incorrectly, and will tell you what logic to follow to get to the correct answer. In the reading passages, it would be nice to know where I can find evidence to justify the "correct" answer. In the grammar section, it would be nice to know which rule I'm violating. Any test guide should always come with some testing strategies. I.E. If this question is taking up too much time, skip it and go to the next one. This guide lacks simple strategies like that. Simple strategies like that could be useful when incorporated into this guide because there are certain sections on the exam that you can go back to previous questions, but some sections where the "back" button is disabled. Overall, if you've never seen an iTEP exam before, this book is certainly helpful in that it will give you an idea of what you will be testing for. However, this book alone won't help you achieve a score of 6. The table of contents itself will tell you there are only 86 pages of actual content covering test material. That's not enough to cover how to excel in the exam.

Don't buy it
Format: Paperback
It does not prepare for the real test. Using it is absolutely not enough to be approved with good grades. Too expensive for what it offers.
