Well, with the Fabtech lift, the geometry is kept normal because of the longer spindles. With the leveling kit on top of it, it puts the geometry just about where it would be if you had a leveling kit on a stock truck. It doesn't ride any more rough than it did when it was lifted without the leveling kit. I'm sure that it does put stress on the ball joints, but the components aren't anywhere near being at an "extreme" angle.

do you have any problems with running the leveling kit upfront with the lift?....people are saying it messes with/puts stress on the geometry and it rides rough in 4x4...so i have been told...any input?....damn your tires look like 40's!!

I have the 6" Fabtech kit, when an AutoSpring 2.5" leveling kit up front. I'm running a 5" block in the rear with a 1.5" shackle. The wheels are 20x10 4.75" BS on Nitto 35's. The only thing that I had to trim was the front valence under the bumper, but it's not noticeable.

what size is your lift and what tires/wheles are you running? Looking to do a similar lift, i don't want to cut anything though
