An OUO Crossmember Cradle System locates a Profab Quick Change transfer case that is mated to the factory transfer case. This setup lowers the output flanges by 12 inches to help eliminate gnarly driveshaft angles created by the suspension lift. The cradle also serves as the mounting point for the front radius arms and the rear traction bars. Speaking of driveshafts, the Super Duty has a pair of custom Drive Line Tech 'shafts with 1480 joints. With the Profab 1.545:1 case and the stock 3.73:1 axle gears, Anderson says the truck has a final drive ratio of 5.76:1. He says the truck cruises comfortably at 65 mph with the engine turning 2,400 rpm in Overdrive. Thanks to the Quick Change case he can rapidly change the final drive ratio of the rig if he wishes.
