Its going to be my woods/hunting rig. Plans include but are not limited to:
front winch bumper
rear bumper with tire carrier/gas can (maybe a rear winch)
If i were to do it again i would do a transfer case instead of diff gears. When you change out a samurai tcase it has a high range reduction as well. so with a 6.5 gear reduction you get a 20 % high range reduction which is like running 4.56 ring and pinion gears. that way you can keep the strength of the ring and pinion intact. if you ever want to turn it into a crawler they have even lower geared tcases. pirate4x4.com and zukikrawler had complete regeared tcase for $500 - $700 .
if you can pick up the tracker differentials (5.13s) cheap AND you plan on putting lockers in them then performance wise you would do better switching the diffs WITH Lockers. if you don't plan on putting lockers in then i would do the tcase. since you are not going to crawl your samurai you can do a 4 lo or 6.5 gear low gear tcase and have a high range reduction of 12% or 20% respectively.
Save your self the trouble and go ahead and swap in toyota axles. They aren't that much wider and are already geared. They are a much easier swap then you would think and common. Would give you a great base for 33's and something to go bigger with on down the road, if you do chose to go that way.
