ARP Dodge 6.7L Cummins Diesel Girdle Main Stud Kit (2007+)

This ARP Girdle Main Stud Kit upgrades the bottom end of the 2007-and-later Dodge 6.7L Cummins diesel inline-six with high-strength main studs and a main-cap girdle. The girdle stabilizes the main caps and resists flex, while the studs provide more accurate, repeatable clamp load for high-horsepower and high-torque builds. Includes studs, girdle, hardened washers, and nuts.
