my friend has the same exact setup and blew his rear i dont wanna do that
do i need anything to strengthen my steering?
what did your friend break? his rear axle? if youve got d35's, might consider swapping in a 29spl 8.2(bolt in)5, or a ford 8.8 if you can (welding install). the d35 is generally considered 'ok' on 31's, but its a weak axle, they do break easily, especially if abused.
at 4.5", you dont NEED new custom steering, but once again, the stock stuff can break rather easily. if you get the grand cherokee steering, make sure it's off a V8, the 4.0 grand cherokee's got smaller stuff similar to ours. i run jcr under the knuckle, 1-ton steering at about that height, but run larger tires that put more stress on the steering, small 31x10.5's or so should be fine on stock.
THE kit you posted, unfortunately comes with add a leaf's for the rear leaf pack... these usually dont last longer than a year, at which point, you'll have a saggy ass, s-shaped leaf pack. this happens quicker if your stock leaf packs are tired allready. once you start sagging out back, the leafs will allow axle wrap which kills driveshaft ujoints, and generally feels like your rear suspension is playing the bongo's. maybe consider spending a little more for the full leaf pack kit... you will be buying full leafs sooner than you think if you go with an AAL. maybe search 'bastard pack' for ideas on building your own pack smarter than an AAL so it doesnt die so quickly.
PERSONALLY, i would avoid the exhaust unless it's got a hole in it.
