They also allow adjustment for centering the axle in the wheelwell if you have upper and lower adjustable control arms. I believe that they also help with making adjustments for wheel alignments by moving each side of the axle front or back, so that the axles are tracking straight. If your kit has adjustable trackbars, those adjust the axle left and right, so that the axle is centered under the frame.
X2! Great info right there...
Yes, you should be fine clearing 35's on there. On the Driveshaft, just keep a eye on it. You should be fine though.
One thing to mention that has not been before, what are you doing about wheels? This lift needs you to either run wheel spacers or wheels with at least a 4.5" BSing. Just wanted to throw that out there as well.
