- Exceptional Strength: The studs are made from ARP 2000 material, a high-strength alloy heat-treated to a tensile strength of 220,000 psi, far surpassing the capabilities of factory hardware.
- Precision Engineering: Each stud is cold-forged and centerless ground, then thread-rolled after heat-treat. This specialized process dramatically increases fatigue strength and ensures perfect thread engagement for a uniform clamping force.
- Complete Kit: This comprehensive kit includes ARP's parallel-ground washers and hex nuts, designed to provide accurate torque readings and even load distribution across the cylinder head.
- Corrosion Resistance: The studs are finished with a black oxide coating, offering superior corrosion resistance for long-term durability.

Protect your engine's performance with the ARP 200-8793 head stud kit. When you're pushing a 2011-2016 GM LML Duramax engine to its limits, stock head bolts simply can't handle the strain. Increased boost, higher horsepower, and heavy towing can cause factory bolts to stretch, leading to a loss of clamping force and a catastrophic head gasket failure. The ARP 200-8793 kit provides a superior solution, delivering a more consistent and reliable clamping force that secures your cylinder heads against even the most extreme combustion pressures. Each stud is manufactured from a proprietary, heat-treated ARP 2000 alloy, ensuring an incredible tensile strength of 220,000 psi. This isn't just a replacement part; it's a critical and necessary upgrade for anyone serious about the longevity and performance of their LML Duramax.
