The Industrial Injection PDM-06021 12mm Gorilla Girdle With Main Studs is designed to increase block rigidity in your 1994-2002 Dodge 5.9L Cummins. By joining all of the main bearing caps and oil pan rail together, the Industrial Injection Gorilla girdle allows you to make more power by decreasing friction in the main bearing bore and overall alignment of the piston and crankshaft bores. The main bearing girdle will strengthen and stabilize the bottom end of the cylinder block evenly distributing the load across the main bearing caps virtually eliminating main cap walk.
