I got an 06 TJ 2.4L with a D30 Front and D35 Rear. I am curious does any1 have any desent but not too exspensive Axle upgrade reccommendations? I don't wanna upgrade to a D44 I just want to reenforce my axles with regearing to 4.10. Also if I upgrade the rear do I need to on the front also? I heard the D35 are not too strong but the D30 are ok.
Thanks in Advance.

Your D30 is stronger than you D35. There really arent too many cheap upgrades for them. If you regear to 410s and even have 33's on them youll be fine and shouldnt have to worry. If your worried about breaking an axel shaft upgrade to new shafts for a couple houndred bucks.
Someone makes a kit for the 35 called a "Super 35" ... Not sure what all is in it but i've heard of several people using it. It is an upgrade... But it'd almost be easier to just get a D44 in the first place.

make CRAZEDLIST.ORG your best friend. i found Alloy USA 30 spline shafts for $100 shipped and a Detroit 30 spline full carrier locker for $218 shipped. BUY USED but just make sure its all in working condition before you install it. The Super35 from Superior is not worth the money at all if you buy new. if your going to spend the money on a new Super35 kit just get a d44. i was really lucky finding my locker and shafts it took me a couple months and alot of searching put it was worth searching to save almost $720.
There are several "Super 35" kits but most are cheap/weak knockoffs of the real Super 35 kit made by Superior Axle. Superior Axle's Super 35 kit replaces the stock 27 spline carbon steel axle shafts with hardened alloy 30 spline axle shafts and includes a locker of your choice like a Detroit Locker, ARB Air Locker, or Eaton E-Locker. It's a superb upgrade that will allow you to reliably run up to 35" tires. The alternative to the Super 35 if you don't want a locker is Superior Axle's "C-Clip Eliminator Kit" which replaces the OE shafts with hardened alloy 27 splne axle shafts. Plenty wheel that kit on some extraordinarily tough trails and it holds up, many with 35" tires and lockers. So long as it's from Superior Axle, you're golden.
I wouldn't worry about the front Dana 30, it's ok with being locked with about the 35" tire size. As Cavediverjc said, the front Dana 30 is not any stronger than the Dana 35, it just never sees more than about 50% of the torque/stress the rear axle does on a regular basis.

Heres my tidbit I put into everyone who is thinking about regearing. Swap Axles, itll save you alot of money. If you look around for a week, for a month youll find someone who will be selling their regeared/locked axles for $500-$700 guaranteed. This is opposed to spending $1200 on parts and labor.
However when you do switch axles, make sure you find someone who can swap it as a friend told me if I filled up his $80 gas tank he would do it. He did one axle and left, fortunately I had other friends who helped me but its not like any of them knew.
= ( Well I bought a S35 rear locked with Detroits and D30 front locked with Detroits regeared to 4.56 for $400, for the price though, I had to give the guy my axles. Also I dont know if it is a true S35, Ill find out one day on the trail. But if it is a true S35, then there you go.
As for a D44, I do agree it would be difficult to find one for cheap
I also saw a S35 and D30 locked and regeared sold on Jeepforum for $700 asking right after I had bought mine.
If they are good axles, I'm considering going with a setup somewhat like this:
- Dana 30 Front Axle Shafts by G2
- Truetrac by Detroit Locker
- Dana 35c High Strength Rear Axles with Detroit Locker
- Dana 30 4.56 Ring and Pinion Set by G2
- Dana 35 4.56 Ring and Pinion Set by G2
- Dana 30 Master Overhaul Kit by G2
- Advance Adapters Heavy-Duty SYE & Tom Woods Drive Shaft
I've Got a 3.5" Lift on the way and the possibility of a rear disc brake conversion kit.
I've looked into the Superior Axles Super 35 kit, but it's too far out of my price range right now. If anyone sees something wrong or incompatible with what I've got here, or has a better suggestion, please let me know! Thanks!!!
