Reinforce Your Bottom End Before It Bites Back

If you're building serious power with your 1994–2002 5.9L Cummins, the Industrial PDM-06021 12mm Gorilla Girdle with ARP XL Main Studs is a must-have upgrade that keeps your block together when things get intense. Whether you’re running big boost, launching at the track, or hauling heavy day after day, the extra support this girdle provides can mean the difference between a dependable build and a split block. It locks down your main caps, spreading stress across a solid plate that resists flex and distortion under pressure. Pair that with the included ARP 2000 main studs torqued to 125 ft-lbs, and you’ve got a bottom end setup that’s built to take abuse without flinching. This is the kind of hardware you bolt in when you’re serious about holding horsepower and torque the right way. It’s not flashy, but it’s absolutely essential. If you’re already investing in power, this is the insurance policy that keeps it all together.

Engineered To Eliminate Main Cap Flex And Crank Movement

The Industrial Injection 12mm Gorilla Girdle Kit with ARP XL Main Studs is designed to reinforce the main bearing structure of 1994–2002 Dodge RAM 2500 and 3500 trucks with 5.9L Cummins 12-valve or 24-valve engines. Under heavy load and elevated RPM, factory main caps are known to flex or walk, which can lead to bearing wear, crankshaft misalignment, and eventual failure. This girdle acts as a structural brace across the main caps, distributing stress evenly and minimizing distortion during high cylinder pressure events. The included 12mm ARP 2000 main studs are engineered to handle extreme clamping force and torque down to 125 ft-lbs, providing superior thread engagement and tensile strength. The system helps improve crankshaft stability, reduces main cap movement, and is especially critical in race builds or high-torque towing applications. Precision fitment ensures the girdle mates properly to the block and clears internal rotating assemblies with no modification. For builders looking to extend engine life and push performance limits, this upgrade is a smart foundation for long-term durability.
