Industrial Injection Dodge 12V 2nd Gen 12mm Gorilla Girdle w/ARP XL Main Studs

Industrial Injection is well-known for building robust performance parts for diesel trucks, and this 12mm Gorilla Girdle with ARP XL main studs is a prime example of their work. If you're pushing your 1994-2002 Dodge Ram 2500 or 3500's 12-valve engine beyond stock power levels, this girdle is designed to add significant strength to your crankshaft main bearing support.

The core of this upgrade is the 12mm thick steel girdle, which essentially acts as a reinforced main cap support system. It bolts over the existing main caps, tying them together and to the block deck. This dramatically increases the rigidity of the bottom end, helping to prevent crankshaft flex and main cap walk under high torque and RPM loads. This is crucial for engines that have been modified for increased horsepower and torque, as these stresses can easily lead to catastrophic failure of the stock bottom end.

Included with the girdle are ARP XL main studs. ARP is a trusted name in fasteners, and their XL studs are a step up from standard ARP studs, offering increased clamping force and durability. These studs replace the factory main cap bolts, providing a more secure and reliable hold for the main caps and the girdle itself. This combination of a thick steel girdle and high-strength ARP studs creates a well-built foundation for your high-performance diesel engine, giving you more confidence when you step on the throttle.

This kit is designed as a direct bolt-on for the 1994-2002 Dodge Ram trucks equipped with the 5.9L 12-valve Cummins engine. While the girdle itself is a substantial upgrade, remember that a successful high-performance build often requires attention to other components as well. Ensure your connecting rods, pistons, and crankshaft are also up to the task for your intended power goals.
