This is our “drop in” girdle designed for 03-current 5.9L and 6.7L engines. .750″ thick on the main caps, and .375″ thick on the block! No Block, main cap, or oil pan clearance is required! This same design is used in all of our engine builds from 1000hp to 3000hp. Available in factory 12mm as well. Includes ARP studs, ARP lube and instructions. (It is recommended to have the main caps align honed in case of any bore distortion from the added clamp load).
