If you're looking to boost your Cummins engine's horsepower, the Gorilla Girdle from Industrial Injection is a must - have. This girdle is designed for 2003+ Dodge Ram 2500/3500 trucks with 5.9L or 6.7L Cummins engines. High - horsepower engines under high RPM can cause the engine block to flex, leading to main cap walk and misalignment of pistons and crankshaft bores. The Gorilla Girdle solves this problem by evenly distributing the load across the main caps, strengthening and stabilizing the bottom end. Part number: PDM - 06020. Features include 1 Gorilla Girdle, 14 large - hole top spacers, 12 small - hole bottom spacers, 1 rear main spacer bar, 2 12 - point rear main stud nuts, and 12 Nylock main stud nuts. It's available in 12mm or 14MM. Note: Read the instructions before starting. For 12mm ARP 2000, torque to 125 ft lbs. Some 6.7L Cummins engines with a factory windage tray instead of a girdle need early - style longer oil pickup tube bolts and an early - style oil pickup tube (Cummins oil pickup tube part number: 3949692, qty 1; Cummins oil pickup tube bolt part number: 3902460, qty 2).

Using the Gorilla Girdle is a great way to enhance your engine's performance. First, make sure to read the instructions carefully before you start the installation. If you choose the 12mm ARP 2000, remember to torque it to 125 ft lbs. For certain 6.7L Cummins engines, you'll need to get the early - style longer oil pickup tube bolts and an early - style oil pickup tube. After installation, it's a good idea to regularly check the girdle and its components for any signs of wear or looseness. Keep it clean and dry to prevent rust and damage. If you notice any issues, replace the parts as soon as possible to ensure your engine runs smoothly.
