You can combine body/suspension lists and get 5"-6" of lift. If you have a 2wd, you could get away with 2-1/2 or 3" coil spring spacers, if you have a 4x4, anything over 2" would put the front CV joints at an extreme angle that could result in pre-mature failure. With the combined lifts I think you can get 33-35" tires? There are a couple guys on here (dakkkota, hendrixx324) who have body/suspension lifts and really big tires, maybe they will chime in as well. I do know that really big (33" and over) requires major fender liner trimming. Welcome to the forum and good luck with your truck. Be sure and post some pictures of your truck....
