Thumbnail Filmstrip of 2006-2010 Duramax Diesel Main Stud Kit ARP 230-5402 Images
Your GM Duramax diesel engine is a beast, but even the strongest engines have a weak point. When you push your 2006-2010 LBZ or LMM 6.6L Duramax with performance upgrades or heavy loads, factory main bolts can stretch, leading to main cap "walk" or "fretting." This can cause catastrophic and expensive engine damage. The ARP 230-5402 main stud kit is a simple yet crucial upgrade that eliminates this risk. By providing a consistent and powerful clamping force, these studs keep your main caps locked in place, ensuring the integrity of your engine's bottom end. Each stud is manufactured from a proprietary 8740 chromoly steel, heat-treated to a tensile strength of 190,000 psi for unmatched durability and reliability.
- Superior Strength: Made from 8740 chromoly steel with a tensile strength of 190,000 psi, these studs are engineered to handle extreme stress and prevent main cap movement.
- Precision Engineering: The studs are centerless ground for perfect concentricity and thread-rolled after heat-treat, a process that significantly increases fatigue strength and provides a uniform clamping force.
- Complete Kit: This professional-grade kit includes hardened parallel-ground washers and hex nuts, designed to ensure accurate torque readings and even load distribution across your main caps.
- Corrosion Resistance: A black oxide finish on each stud provides excellent corrosion resistance, protecting your investment for the long haul.
Upgrading to the ARP 230-5402 main stud kit is an essential step toward building a truly bulletproof Duramax. Whether you're building a high-horsepower race engine or simply want to ensure your daily driver is as reliable as possible, this kit provides the foundation you need. It's a proactive investment that protects your most critical engine components, giving you the confidence to unlock your Duramax's full potential without fear of a bottom-end failure.
