like slo96 said, if you want big tires and want to beat the piss outta it, put a dana 44 up front and a 9 inch out back from an old scout.. or a set of 10 bolts, 12 bolts, dana 44s, 14 bolt, or even a 60 if you really want over kill...
staying with IFS:
-very limiting factor, from the lack of front end articulation
-as long as you stay under 33s you will have minimal problems strength-wise.
goin to 33s, with IFS:
-if you want 33s.. 3" body lift and turn the bars up..
-wheelin hard will increase the amount of breakage, having some 33s that bite--- some good MTS or TSLs...rearend breakage and front chunk brakage is most frequent to break.
goin to 35's., with IFS:
-This is a 80% street, 20% trail combo!!!!
-5" trailmaster and 3" body lift.
-id recommend regearing it also, the 4.3 strains its tail off with 3.42s which most 4.3s came with. You can go to 4.11s. makes a huge difference.
-with the trailmaster lift on-- you will encounted halfshaft breakage problems if you drive hard off road..wider wheels required to run 33s will wear out your steering components very quickly. go on and get all new front end stuff if you plan to do this lift combonation. since you talk about beating the piss outta it, you will be replacing stuff very often so have a large quantity of tie rods, idler arms, halfshafts, and eventually transmissions..
goin to 36s with IFS:
-not smart to do if you dont like the sound of metal grinding and crunching!!!!!!
-Need a 5" Trailmaster, 3" body lift and superlift uppser A-Arms to turn the bars up max.. (due to alignment issues) these arms are longer than stock and are a LOT stronger, the upper factory arms are weak as piss. ive bent several of them with the trailmaster lift on my truck.
you WILL be ripping the inner joint of the halfshafts out very frequently having this much lift unless you make custom brackets to lower the front chunk because of the angle on the halfshafts.
with SFA the choices are endless.....
