So I guess 34's, locked diffs, a high lift jack, tow strap, and a couple of other Jeepers are recommended then?
First time I went there was on 33's and open diffs, had a blast, got plenty of trail time. If you can up up Sidewinder and Bronco Peak (not 3A) at Corral Canyon you can run a bunch of trails at Superstition. However, depending on how well, or badly, the Jeep is put together will directly influence not only trail choice, but the quality of the trip. Of course driving style is just as big a factor. I see more people break from the right pedal than anything else.
On some of the trails we wandered over 33's and open diffs would have made it fine, might have needed a little help, but would've made it. A few others were in the league of at least 35's, hard lockers, lift, built axles and more or you'd be up for a long day of dragging the Jeep back.
We saw as many Jeeps that were mildly built as ones that had big dollars thrown at them. If you want to have a fun time, head out, pick the right trails and enjoy. If you want to run the harder stuff be prepared to spend some serious money before going or take very patient friends and plenty of spare parts. There's at least four trails we ran over last weekend that I would not want anyone with a Dana 35 on the trail at the same time as me, others, I'd go with someone with a bone-stock Jeep as long as they had tow hooks and followed directions.
As for the hi-lift. I finally sold mine, hadn't used in over three years, and even then, the last time I did use it was installing a body lift in a garage. The best use for a hi-lift this last weekend was to pass the safety inspection for the organized runs.
