Industrial Injection 12mm Gorilla Girdle with ARP Main Studs 03-18 5.9L / 6.7L Cummins

For the guys out there wanting to run higher horsepower out of their Cummins, the Gorilla Girdle from Industrial Injection is what you need. Under high RPM with higher horsepower engines the block itself will actually flex. This causes main cap walk and improper alignment of the piston and crankshaft bores. The Gorilla Girdle strengthens and stabilizes the bottom end by evenly distributing the load across the main caps. This kit includes the ARP XL Main Stud kit and everything needed for install.
