Out back is a monster GM Corporate 14-bolt. Overkill for a flatfender you might say, but also better insurance against breakage than the stock Dana 44. With 38-inch Swampers and 4.56 gears there is still a good amount of clearance under the shaved axlehousing, and by using a standard axle with dualie hubs, the wheel mounting surfaces are just 63 inches wide. Rear suspension was built for flex and comfort on bumpy trails by using Goodyear airbags off of a Freightliner semi and a three-link with wishbone suspension.
