does anybody else have the horrible looking bowed suspension on the front? when you crank the t-bars on a halfton the bottum of the tires set inside more than the top. on my hd the top of the tires look like they are guna rub the valve covers!!! (not quite that bad but you get my drift).
il get sum pics up here this weekend.

thanks guys.

Like a desert racer? Yea, my truck shows that too. Bigger wheels and tires make it more obvious. I just put the skinnys back on with the same crank, you can hardly see it now.

Any time you lift a truck your going to run into camber issues which most suspension companies address (especially IFS). When turning the torsion keys to get alittle more lift out of your truck your messing with the camber. What its doing is drawing the wheel down causing the suspension to articulate. In doing so the upper and lower arms have to follow that movement. Well in doing this the upper control arm is set (via stock height) to operate in that normal arch. When you crank the torsion bars it causes your upper arm to basically get shorter in its arch causing the camber of the wheel to be more negative than at 0 degrees which is normally factory setting. What most companies will do is compensate for this by making new upper control arms to keep within the factory specs. Thats what your seeing. The down side, uneven wear on your tires and alignment issues.

I'd say it depends on how long you intend to wait and how many miles you drive.

Id just wait if you plan on doing the lift and new tires. Just my opinion if you're going to do the lift in the next couple months or so.
