Protect your investment with the ARP 247-5403 main stud kit, a critical upgrade for your 2004 and newer 5.9L or 6.7L Cummins diesel engine with a factory block stiffener plate. The crankshaft is the heart of your engine, and its security relies on the main bearing caps. Under the high stress of increased horsepower, heavy towing, or high-RPM driving, factory main bolts can stretch, leading to main cap "walk" or "fretting." This movement can cause premature bearing wear and catastrophic engine failure. The ARP 247-5403 main stud kit is designed to eliminate this risk by providing a superior and uniform clamping force that locks your main caps in place. Each stud is manufactured from a proprietary 8740 chromoly steel, heat-treated in-house to an impressive tensile strength of 200,000 psi, ensuring unmatched strength and durability.
- Eliminates Main Cap Walk: Engineered to provide a consistent and powerful clamping force, these studs prevent the main bearing caps from moving, protecting your crankshaft and bearings.
- Precision Engineering: The studs are precision J-form thread-rolled after heat-treat, a costly process that dramatically increases fatigue strength and thread life, ensuring a secure and reliable bottom end.
- Superior Material: Manufactured from a proprietary 8740 chromoly steel and heat-treated to an impressive 200,000 psi tensile strength, these studs are far stronger than OEM bolts.
- Complete Kit: This professional-grade kit includes hardened parallel-ground washers and high-quality nuts, ensuring accurate torque readings and even load distribution for a perfect build.
Upgrading to the ARP 247-5403 main stud kit is an essential step toward building a bulletproof Cummins. It's a proactive investment that protects your most critical engine components, giving you the confidence to push your diesel to its full potential. Whether you're building a competition engine or simply want the peace of mind that comes with a reliable daily driver, this main stud kit provides the robust foundation your engine deserves.
