The Industrial Injection PDM-06021 12 mm Gorilla Girdle With Main Studs is designed to increase block rigidity in your 1994-2002 Dodge 5.9L Cummins. By joining all the main bearing caps and the 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.
Kit includes: Gorilla Girdle, ARP XL Main Studs, spacers, and hardware for installation.
Note: 12v owners must check the engine for 12 mm or 14 mm main studs and choose the kit accordingly.
