Just look at things this way. I have built many Samurais over the years. With the puny little 1.3 with no power and 31s or 33s. Stock transfercase gears with 5.12s in the axles. went down the freeway at 70-80 mph just fine. Some even dragging a small back-half Sami trailer at the same time. You just have something that ways a little more with more power and better aerdynamics.
 The 4.24 gears will only take care of off-road ability. Won't change going down the freeway at all.

What are you trying to say? That I don't need the high range reduction and I should just get the TT gears? I'm starting to think that as well because I' not really planning on running 33's. Too much other stuff that will go wrong with that big of a tire.

I am running 33's and have not had any problems with that big of a tire

Well this is how I see things.

To run 31's all I need to do is buy the tires and get some gears so I can actually crawl properly. Maybe beef up the idler arm mount.

To run 33's I'll first need to ditch my 1.5" spacer lift and get a 4" lift and possibly a 3" body lift instead of a 2" BL. I'm not afraid to trim the front fenders but there isn't a whole lot of room to trim out back because the doors are about 3/4" from the fender. Then there is the matter of gearing. I'd need to swap in the 2WD trans/Sammy transfer case to make it drive adequately on the road (this is my DD, I forgot to mention), most likely the front axle wouldn't hold up under the rigourous wheeling we have around these parts so I'd need to swap in a steel diff from a V6 Zuk. While I'm doing that I may as well toss in yota CV's and the Hagan widening mod. It's alot of work and alot of money, that nets me a few more inches of ground clearance but I think I'd rather just buy a different vehicle than dump another 3-4 grand into a vehicle I bought for $3700.
