the RC and TC are the same co. used to make unsafe crap lifts and still do . the rancho is ok except you cant air down very far without your tires hitting the steering knuckles etc.
most mass produced lifts are for looks , if you really want it to kick some crawler azz cut off all stock suspension addd a solid front axle and widen the track by 4-6 inches then you could go up a ways and run some 40's but you would want to get a older Z71 front diff , its the same as ours but cast IRON much more bullet proof than these aluminum ones . thats where i would begin
then taper the nose and tail , fenders gone etc. etc. probably not too pretty
