Re: Not sure if this belongs here, but .....
my ranger was fine with a 4" lift. but mine is also 4x4 and a 93. but MOST vehicles in general are ok without modifying most parts(like brakelines, etc) at 4" and below, UNLESS you plan on flexing the crap outta it. Cuz if you plan on flexing your axle you'd better extend the lines... and you can really only extend them that i know of by either taking them into a shop(what i did, extended mine 12"), re-routing them, or by buying pre-made extended lines from skyjacker, i think they make em.
