Just measured again. Inside of TDC of Tire to frame on Driver's Side is 10-3/4" and on Passenger Side it is 10-5/8". Mine has not shifted.You are lucky then because every one I've ever installed/seen has shifted the axle to the driver side noticeably without a relocation bracket or longer track bar. I only have the 1.5" Leveling kit on mine and it is noticeable if your looking for it. Humor me and look again down the body line and I bet you'll notice the front passenger tire is just inside (or further inside) the wheel well while the driver's is just outside (or further to the outside). Sometimes it's hard to tell with stock tires. All leveling kits will do this in my experience unless you relocate the track bar mount or intall a longer/adjustable track bar. Even in light of that, it's nothing alarming. 35,000+ miles leveled and no problems.
