You guys are just looking in the wrong places. There are tons of lifted S10's out there. Even a site dedicated to Extreme S10's.
Yes, you can fit 33" tires inexpensively if you know what you are doing. 3" body lift, minor fender trimming, a little firewall massaging and they fit just fine.
Don't waste your time or money on stock Jeep axles. They aren't any stronger then your IFS stuff. The only exception would be the D44 front axle.
there used to be a kit made for the solid axle swap, many are dublicating it in there own swap.
I prefer the S10 over a Jeep Wrangler style for many reasons.
Better wheel base, boxed frame, 4.3L V6, easily swap in a V8 (especially if you have a 4.3L, hooks up to the same tranny), flat bottom, and parts are everywhere. Not too mention the 700R4/4L60/4L60E tranny has great gearing, 3.06 first gear and .70 overdrive. Plus the t-case is a NP207/231/233 with 2.72 low gear. I my personal opinion the S10 is a much better platform for a serious off-road rig then a Jeep. The only thing you need to do on the S10 is swap under beefy soild axles. With the Jeep you need to stretch the frame, swap in bigger axles, and swap in an engine/tranny/t-case. Sure the Jeep is better suited for out of the box wheeling, but after that, the S10 has the advantage. Check out those bigger Jeeps, what engines are they running? What trannies are they using? Where did they get those engines and trannies?
