Hey,
I'm running 35's on mine, but not for long. The extra strain from a bigger tire bouncing on it has bent two housings, the first being my 10-bolt with 4.56's in it, the second being my stock axle running 3.42's. You can give up hope on the Gov-Loc ever working with a tire over factory size. I used to run in mud a little and I have taken it rock-crawling, but a 14-bolt is still going to go under the rear-end. I've been told a 10-bolt will stand up to a 36" tire, ON THE STREET ONLY, but these roads in southern North Carolina have put a hurtin' on that P.O.S. axle.
