looking to fit 31"s under my 97 s-10 blazer, was thinking the blazers ran torsion bars if so could i crank the bars up front to get a small lift 1-2" and in back do an axle flip or add blocks, if these things are true and it would work would i have to fit a bigger shock on it what will fit under my s-10 stock with no problems turning or bottoming out  

what is the stock tire size?  29?

I don't have a blazer, but a frontier and it came with 30s from factory and i was about to fit 32s with small Tbar crank.

You should look into getting AAL full pack instead of blocks  

There is only one realy positive to traction bar lifts: the price. But to my way of thinking, the negatives far outweigh this one positive.
1 - It's very common for this to alter your camber beyond it's adjustment range.
2 - You'll have very little downward suspension travel, and often end up with LESS flex than you had stock.
3 - The ride will SUCK.
4 - Your shocks will probably have to be replaced.
5 - The geometry of your suspension will be screwed up. Meaning that constant practice will make you the Worlds Foremost Expert on replacing balljoints and halfshafts.  

It can be done. But what the other guys said is correct.

There is  several things that I do not agree on at all with this guy but he is pretty much dead on on this one with his answer.  

well thanks alot guys, im pretty new to suspension, as far as what you can and cant do. all information was taking into consideration im thinking it was a bad idea in the long run, thanks guys  

I had a S-10. In order for me to put 31's I put in a 3"bodylift and some minor trimming. It rubbed on the front swaybar a little when locked. Checkout www.s10extremist.org You'll find all kinds of good info there.
