ARP 230-4301 Diesel Head Stud Kit Product Description

Upgrade your 2017–2024 GM 6.6L Duramax L5P engine with the ARP 230-4301 Diesel Head Stud Kit-engineered for superior strength and reliability under the most demanding conditions. Designed as a direct replacement for factory head bolts, this kit is essential for high-performance builds, aggressive tuning, heavy towing, or off-road applications where head-lift and gasket failure are common concerns.

Each stud is precision-manufactured in the USA from ARP’s proprietary ARP 2000 material, delivering an impressive 220,000 psi tensile strength to ensure maximum clamping force and prevent cylinder head movement even under extreme boost and combustion pressures. Threads are rolled after heat treatment for optimum fatigue strength, while the centerless ground studs guarantee perfect concentricity. The kit features heat-treated chromoly steel 12-point nuts and parallel ground washers, all finished with a durable black oxide coating for long-lasting corrosion resistance.

Installation is straightforward thanks to broached stud ends, which simplify head removal and mounting. The kit also includes 0.5 oz of ARP assembly lubricant for a smooth, safe installation process.
