Aaron found the stock IFS was certainly not up to the tasks he planned for the truck and its components were rapidly wearing anyway. Out came the torch and grinders, and the IFS dropped to floor. In its place resides a solid axle conversion. Aaron opted for a high-pinion Dana 44 spinning Yukon alloy axle shafts out to Warn Premium hubs. Locking those shafts together is an ARB Air Locker spinning 5.38 gears.
