After building a couple trackers now, I'm still very happy with the 29" tires. Unless you jump all the way up to 35" tires, it's hard to get correct gearing, and the 1.6L just has a hard time turning anything larger than 29" with the weight of the 4-door. The only gearing options right now are:
* The
ultra rare 5.38 diff gears
* Toyota or Dana 44 axles (I think they go up to the 5.71 and 5.8x respectively)
* The Samurai t-case (The
ONLY transfer case out there that gives high and low range reduction! Happens to be 1.4:1 which is perfect for a 35/37" tire)
The Samurai T-case can be added behind your tracker t-case for a dual case setup (the sami case would be your "main" t-case, and the tracker one would act like a doubler for low low crawl), or you can source a 2wd transmission, and slap on the sami case to that. RockRat makes an adaptor for the dual-case setup, or you can make your own:

http://forum.ih8mud.com/40-55-series-tech/218795-warn-vs-aisin-hubs.htmlBody lifts are cheap & easy. But, they don't provide any additional ground clearance between the frame & the ground... all the while they lift the center of gravity. I don't like raising the center of gravity without getting more frame clearance. Cut the wheel wells or bang around the inside fender wells if you need to make more room (called virtual lift). Done right this looks clean, clears room for bigger tires, and doesn't raise your CG.
But trust me on the 29" tires... if you don't get a larger engine, or proper gearing, you'll be hating life. Just depends on what you want really though. If you want to...
* Look pretty: Lift away & get bigger tires
* Wheel better: Stay at 29" tires, get 4.21:1 Rockmonster low-range gears & lock the diffs (welded, spool, LockRite, or ARB - DO NOT use EZlockers as they grenade easily in zooks)
Either route will cost you the same. One will make dudes look at you and say, "something cool here" and the ladies will say, "I wonder what he's over compensating for" - the other will make guys with big tires & lifts cry when you drive around them in the rocks.
