How are you liking those tires? It’s most likely what I will go with when I get 35s and 5.29s.
I haven't had them long but so far I love them. They're a good bit louder and don't do as well on ice as my last tires but that's to be expected because of the whole MT vs AT. For a mud terrain though they do very well on packed snow as long as you have them at the right psi. They also kill it in deep snow, they clean out so damn well. I'm really excited to get them in the rocks. Only complaint is they don't give you room for error in the snow. They dig holes. Fast lol
Second pic is also at 5psi,with no beadlocked, and I did not blow a bead all day.
I believe it is an option. Or at least nitro lists it and Zuk has a few write-ups. But they're all in the old style 7.5 diff not the clamshell. It may not fit in the clamshell because the ring is so thick, I know there isn't much room in there. It's also not a super common ratio just because most don't run it untill they're trying to push 40s with a 22rJust something to consider below of the Ring/Pinion tooth counts. Once you start getting into the higher gear ratios, the pinion gear gets smaller. So considering the below gear ratios, 3.73 would be the strongest followed by 4.30. Well I've broken two sets of 4.30 already (once with 33's and another with 35's) Both of those breakages were avoidable if I drove a little smarter. I have broken a set of 5.29 gears, but that was due to the backlash adjuster not being set properly (poor install), causing the whole carrier to shift to the side almost an inch and not have any contact between the ring and pinion gears. Chipped/chewed up the pinion gear a little, but the cause was from install, not gear strength.
3.73 = 41/11
3.90 = 39/10
4.10 = 41/10
4.11 = 37/9
4.30 = 43/10
4.56 = 41/9
4.88 = 39/8
5.29 = 37/7
5.71 = 40/7
I do believe that 4.88 is stronger than 5.29, but how much is what I don't think is as big of an issue as people claim. Smart driving is more important IMO. Too bad we don't have a 5.71 option for our front diff's or I would have probably gotten that ratio instead.
