Out back, the stock Dana 70 axle has been replaced by a Ford 10-1/4-inch axle. The Ford axle has 4.10 gears, a TSM disc brake conversion, and the stock Ford limited-slip differential. The leaf-spring suspension is stock but has a shackle flip and Pro Comp ES3000 shocks have been added. The tank you see on the driver-side in front of the axle is a custom 18-gallon fuel tank. It is made of aluminum and compared to the factory tank it has had three inches removed from the bottom to improve ground clearance.
