Default Re: what can go wrong??

With Stock 4.5" backspacing and a Fabtech 6" lift you should be fine.

I am not a fan of spacers as the H2 already does a good job at eating hubs in stock form. But they are safe to use. Just put more stress on the hubs causing them to wear faster.

The 4:10 gears will hold up fine to larger tires but you going to miss allot of the low end torque you used to have.

My only concern when going to a 39+" tire is axle strength. I have 37's and can easily break a 1/2 shaft when I lay the throttle down.

Alot of the guys i know running tires over 39" always carry spare 1/2 shafts because they break them so often. My other worry is Diff and xfer case damage with tires that big too. I know the drive train on the H2 is stout and on a light weight buggy they would do fine with those big tires. But the H2 is a damn pig lol.
