yeah I think you will be fine with 37's. yeah I'm 230:1 but I really havnt even used the lowest gear yet, its way too low for snow bashin. I didnt completely break my stock hub gear. The groove around the gear that holds the snap ring was cracked and pieces were breaking off of it. luckily I caught it before it completely broke and caused damage to the splines. The Longfield hub gears are 65 each
definately let me know how them stock inners do this summer man
damn that runner looks sweet with 4'dees
