37s on dana 30? Anyone doing this?
#31
THIS RIGHT HERE. I had a buddy that ran 3.21's on 37's (he now has 4.10's and 40's). He had to smash into every rock, ramp over every obstacle, just to keep up and not stall. His excuse was "oh well my ring gear is stronger." There I was with 5.38's and 37's, Idling up every obstacle that he was hitting wide open. He also refused to air down, saying that he would get too much traction and break parts. "higher gears means a stronger axle" translates to "I'm too lazy to install proper gears" It may be stronger, but you are increasing shock loads and breaking everything else. And honestly making your wheeling experience less fun.

I currently have a JKU Freedom edition (front is a D30) and Im having 37x13.5 with 4.5 lift installed I'm also regearing to 4.88 and putting sleeves and gussets on. Regardless of what others are saying I feel confident about how the axle will hold up. Anything could happen though but If your an abuser or if you aren't prepared for the worst then I wouldn't do it.

"Going easy" on a D30 is really not going to reduce risk of failure by much. Most of the ring and pinions we have seen break, have happened while crawling. We broke a 44 front ring gear crawling in 4lo with a Rubi t-case in a manual trans with zero throttle. A little wheel slip and then hooking up is all it takes sometimes.
