XDP XD3006HS X220 SERIES HEAD STUD KIT 2001-2016 GM 6.6L DURAMAX LB7/LLY/LBZ/LMM/LML

The XDP X220 Series Head Stud Kit XD3006HS sets a new standard for durability and performance in high-horsepower 2001-2016 GM 6.6L Duramax LB7/LLY/LBZ/LMM/LML engines. Designed to withstand the intense pressure of high-performance applications, these head studs are made from 8740 Chrome Moly with a proprietary element for superior strength and longevity.

Engineered with a tensile strength of over 220,000 psi and a yield strength of more than 210,000 psi, these studs prevent cylinder head lift under increased combustion pressures. Unlike factory bolts, these studs will not stretch, ensuring a secure and reliable seal every time. The threads are rolled after heat treatment to enhance fatigue strength and provide optimal clamping force.

Featuring a vertical axis force application, these studs offer a more even clamping force, allowing for precise torque readings and consistent performance. Reusable and superior to OEM Torque-To-Yield bolts, these studs simplify engine assembly and ensure proper alignment of cylinder heads with each use.

Manufactured in an ISO/TS 16949 quality control facility, the XDP X220 Series Head Stud Kit includes washers and 12-point nuts for a comprehensive installation process. For added convenience, consider adding the XDP Thread Cleaning Chasers (XD40124TC and XD40128TC) for thorough thread cleaning before fastener installation, guaranteeing accurate torque readings and peace of mind during engine builds and head gasket repairs.

Upgrade your engine's durability and performance with the XDP X220 Series Head Stud Kit, the ultimate solution for high-horsepower applications in GM Duramax engines.
