XDP XD3017HS X220 SERIES HEAD STUD KIT 2017-2023 GM DURAMAX 6.6L L5P

The XDP XD3017HS X220 Series Head Stud Kit is the ultimate solution for upgrading the OEM head bolts on your 2017-2023 GM 6.6L Duramax L5P engine. As you start adding more horsepower and torque to your Silverado/Sierra, ensuring that your cylinder heads are securely fastened becomes paramount. The factory bolts may struggle to withstand the increased pressure of high-performance applications, potentially leading to cylinder head lifting and head gasket failures.

Crafted from 8740 Chromoly Steel with a special proprietary element, these studs offer unmatched strength and durability, eliminating the risk of stretching that comes with stock bolts. The threads are meticulously rolled after heat treatment to deliver maximum fatigue strength, ensuring your engine stays locked down even under higher combustion pressures.

With a remarkable yield strength of over 205,000 psi and a tensile strength exceeding 225,000 psi, these studs provide a robust hold for your cylinder heads. By switching to studs, you not only enhance strength but also achieve more precise torque readings, thanks to the vertical application of force that results in more even clamping pressure.

Moreover, the studs facilitate easier engine assembly and precise alignment of cylinder heads every time, making them indispensable for high-performance applications. Unlike the OEM Torque-To-Yield bolts that need replacement after each use, the XDP head studs are reusable, offering long-lasting reliability and performance.

Manufactured in an ISO/TS 16949 quality control facility, these studs come complete with washers and 12-point nuts for a comprehensive installation. To complement your installation, consider adding the XDP Thread Cleaning Chasers and XDP X-TRA Slick Engine & Fastener Assembly Lubricant for optimal thread cleaning and lubrication during assembly, ensuring accurate torque readings and enhanced fastener performance.

Invest in the XDP X220 Series Head Stud Kit for unmatched strength, reliability, and performance in high-performance applications, and take your engine to new levels of power and durability.
