Start with some JKU Upgrades. Went from a 2.5 Lift to a Teraflex 4inch lift with Bilstein shocks. Did the Barnes Track bar, Steer Smarts HD Yeti Tie Rod and Tera Flex Draglink. Also got rid of the crappy gearing and went with the 4.88 gears with ARB air lockers and ARB onboard Air.
After completely obliterating my front axle at Windrock I beefed up my dana 30. Went with Carbon Offroad Chromoly axle shafts, Barnes weld-in axle sleeve and Barnes C-Gusset. Upgraded ball joints to the Teraflex HD Ball Joints. And got some new rubber Nitto Trail Grappler 35's. Oh and crushed the Teraflex Steering Stabilizer.
