hey i was thinking of running trailtoughs toyota 5:71 gears in my toyota axles for the kicker.  has anyone used them and what size tire should i run to keep my low good.

thanks

I would say that 35's are a good match for those gears depending what you do with the rest of the drivetrain. Lots of people say the 5.71 are weak but I have no personal experience with that. I put 5.29 in mine and run 36's with lots of gearing ahead of the axles. It is a bit of a slug onroad but really shines offroad. Boils down to what you want it to do?

k because i was leaving my t-case stock so the 5:71's are going in my axle.  i picked up 33's how bad will those be?

That setup should give you decent power onroad and not be too much at risk of breakage. I would get some stronger birfs if you plan to wheel it much though. Here is a link to my build http://www.zukiworld.com/forum/build-diaries-how-to-diy/project-kickota/

I have the Trail Tough kit on a X90. Yota axles & 5:71s. 33" is aprox the size tires I run. I don't think the veh. has the power or weight to break the toyota ring/pinion 5:71's . I've gone through 2 automatic trans. & conv. to 5speed. Now on my second one of those & second motor as well ! Diff's ? No problem as of yet. Now how does the gearing work? fine with 33's. I get on flat ground & pull 5th gear no problem. Low range could be better better but 5:71 is as far as I care to go. 35's or taller would be a problem to pull.
