Industrial Injection PDM-06023 14mm Gorilla Girdle Main Studs with ARP XL for Cummins Common Rail

The Industrial Injection PDM-06023 is a heavy-duty main stud kit designed specifically for 2003+ Cummins Common Rail diesel engines. This kit combines a 14mm Gorilla Girdle with ARP XL main studs to provide maximum strength and stability for the engine block's main bearing caps.

Key Features:

• 14mm Gorilla Girdle design for superior main cap retention and rigidity
• ARP XL (extra-long) main studs manufactured from premium aerospace-grade steel
• Engineered specifically for 2003 and newer Cummins 5.9L and 6.7L Common Rail engines
• Significantly increases block strength to handle extreme cylinder pressures from high-performance builds
• Helps prevent main cap walk and block splitting under high horsepower and torque loads
• Requires stamped steel oil pan for proper clearance (not compatible with cast aluminum pans)

This main stud kit is essential for serious performance builds, competition engines, and high-boost applications where factory main bolts are inadequate. The Gorilla Girdle system distributes clamping forces more evenly across the main bearing caps, while the ARP XL studs provide consistent and reliable clamping force that won't loosen under extreme conditions. Professional installation and proper torque specifications are required for optimal performance and reliability.
