need truck guys help
I purchased a 2002 Silverado 2500 for work truck and am wondering if any of you guys are familiar with them. The back end of the truck sits nice and high, yet the front sits much lower. I have been told that in order to raise it up, I can adjust the torsion bars. It wasn't a huge concern of mine, but now as the weather is warmer out, its the perfect time to mess with it. Has anyone done this before, looking for advice on doing it, possible tricks or things I should look out for. Thanks in advance!

If you have torsion bars you can crank them up a bit....be aware however that it will affect your alignment.

yes, there is plenty of info on how to do it over on www.fullsizechevy.com
good thing about the 2500's is that the 2wd's use torsion bar suspension as well. I went with new spindles with my 1500.

I had a 2 Silverado SSs and a GMC Sierra, my friend raised up the torsion bars while doing the alignment for me.

You need to be careful with screwing with torsion bars. Be aware that it directly affects the angle of CV joints in a 4wd suspension and can cause premature failure as well as causing you to need an alignment.
Also be aware that counting turns on each key bolt and turning them equally will more than likely not yield equal heights. You need to park the truck straight with the wheels straight no extra weight in the truck. Take a measurement from a wheel reference point to a body/fender reference point to get an equal adjustment.

agreed on the torsion bars. I have them on my explorer and there is only a certain amount that you can adjust them before you start screwing up things real quick, and as said before, once you do it, get an alignment to correct the angles you just adjusted. On the plus side adjusting the torsion bars takes all of 10 minutes

just jack the front end up, and crank bolts incounting the turns,you can crank them up without screwing with the alignment or producing any major stress on other parts(cv's,ball joints,tierods, etc..) its when you swap them out for aftermarket keys to get more lift that will cause a problem.
I have done this in my 2001 my 2002 2500hd and my 3500hd dually. no probs

Thanks a lot guys, you are a big help. I will mess around with that this weekend and let you know how it went. I am trying to think ahead, bought an 8 foot PRO western plow for the truck, and with my old 7.5 foot, the front sat way to low. I am afraid that the 8 foot may be to much as it sits now, so I will raise it up a little bit. I will keep you updated how it goes!

My 2001 has the Readlift keys for leveling the front end. It's pretty level but looks a little off because my driveway is so bad.
