shackles will be fine, but shackles are suspension lift, and after 3" of suspension lift, you are right at the line where sye might be needed. do it and see how it rides, check for vibes, and then flex it up and see how much d shaft is left in the t case. if you flex it up and there's on ly a quarter inch of the d shaft in the t case thats bad.
shackles are ok to get one inch out of it, even a one inch body lift isn't terrible, i just hate the way they look, and any more than one is just stupid. but at 4 inches you get to the point where you really need slip yoke eliminator and cv driveshaft. that would be best. and if you wanna spend some money, jump to soa, that is the best yj suspension
Hey neighbor , im thinkin on the body lift or shackle, i swapped my 33's on for the 31's on my new 92 yj, it only has a 3 inch susp lift, i gotta have one more inch or so to make it better when i turn, they kinda rub (33x12.50) which i figured all this would happen, shackle is easier so id rather do that, never done a body lift, my main concern is the driveline angle, i dont want any vibes comin after this! I already got my tcase lowered, so i might be ok no matter what, right? I saw on someone elses post you said you dont like body lifts. So whats my best bet, oh ya and i think they look dumb as shit anyways, but look for my post bout it in yjforum and read what the other guys said and write me back.
Thanks, id like to do one this weekend so asap please, thanks
