Re: body lift
If you ask BigMileageS10 about it, his fathers a GM mechanic. The t-bar crankup is what the service manual calls for when you use a plow. I have seen no ill effects to the CV boots or to the ball-joints. You won't need to crank them too far, anyway. Let me guess you're wanting to fit 31x10.50x15 tires right? I just barely cranked mine up to fit the 31's they do rub at full steering lock on the swaybar, but my truck has 175,000 miles and the pass. CV shaft is original! I replaced the drivers side last summer(before the 31's) It is a 1997 after all, and from what I've seen body lifts will cause more problems than the simple t-bar crank up will. Whatever you decide, good luck.
