The high-pinion rear has 5.29 gears and an ARB Air Locker. The advantage to the ARB in the rear is that when it's disengaged, the TJ doesn't jack or push in weird ways. An open diff works great around town or on the highway, especially in conjunction with the hubs unlocked up front. Off-road, Dan usually leaves the ARB locked in most situations. The larger diameter sway bar is from Full Traction. The stock swaybar links should have been used, rather than the longer Teraflex ones that came with the Pro LCG suspension that are designed to work with 4-inch of lift.
