Can you stick 5.38 Gears in a Dana 30??
 
I got a 2007 Jeep Sahara 4Dr and it comes with Dana 30 in the front and Dana 44 in the back but i cant find 5.38 Gears for the 30??????? And when i look at the 5.38 Gears for the 44 it says for Rubicons only is that true?? Im looking at the Superior Axle Gears on Quadratec.

There is now a mfg with a 5.38 set for Dana 30's that is advertised as safe, but that's just too gear'd for my comfort level. Stick with 5.13's or 4.88's, depending on your driving style and off road needs.

Superior makes a great gear, can't go wrong with them.

What type of trail driving do you do and is your Jeep a daily driver? Stick or auto?

5.13's then. Tons of fun for off road. If you want to gear down even further you could add a RubiCrawler from Advance Adapters. Takes you down from 2:1 to 7.4:1 crawl ratio in your Sahara. Totally unchanged for daily driving.

Heavy mudding? That's some high wheel speed with the potential to snag some rocks and snap an axle or drive shaft.

If you ran 5.13s in a d30 with stock axle shafts, would it be safe to say that if you suddenly gained traction when your wheels were spinning that if something was going to break, it would be the stock axle shafts? Or is there still a high risk of r&p failure?

I have a friend who's gone through three sets of 5.13 R&Ps. Just to damned small for serious wheeling. I would personally not go any smaller than 4.88 and at that, I wouldn't lock it.

Thanks for schooling me. I didn't know anyone was making 5.38s for the D30.

Talk about a tiny pinion gear. Good luck with that.

Started my front 44 build so before i put it in i am gonna bash on this pretty good to see if it holds up.:thumbsup:

Nice. :thumbsup:

Keep us posted as to how well it does. I know I was uber worried on my last JKU with the 5.13s and 37" tires. Too bad it was totaled in an accident shortly after having the gears done.
