Ring Gear

Almost any truck is affected by going to larger tires, and our best advice is to complement those larger meats with some lower gearing. We found a set of 4.56 gears for our GM 9 1/4 front differential, and decided that the addition of an ARB selectable Air Locker would not only help the off-roadability of our truck by keeping both front tires turning when we need it to, but also would help test the idea that a front locker will break parts in an independent front end. To match the front, GM Truck Center replaced the stock 3.73 gears in the rear 14-bolt with some 4.56 gears, but we left the factory Gov-Loc alone at this point.
