dana 35, 33's okay
dana 35 33's and locker: Time bomb

I ran a lockright in the front 30 did great off road and on the street. However in snow covered roads it was not so fun.

I was pondering the same thing my 02 I put a detroit and axle upgrade in the rear and a Trutrac and axles up front. with 31's and 4.56. I liked everything about it but the clunk clunk... in the rear...this was a daily driver. I was thinking of the Trutrac in front and rear but what about the axles? or just change gears 2" lift and 30's

As said above, you really should not lock your rear Dana 35c axle. The reason is that its axleshafts aren't strong enough and really with no exaggeration, one of them will eventually snap while you're on the trail. No matter HOW careful you are, no kidding. And once broken on the trail, it's hard to get the Jeep back to where it can be repaired since the broken axle shaft's wheel will separate from the axle afterwards.

Two options... 1) Lock your front Dana 30 instead. Due to the TJ's axle design, a front locker will NOT affect how it drives on the street in 2wd. Yes I know you've seen advice to only install a locker in the front if you also install manual hubs but that isn't the case with the TJ. You won't even notice its presence in 2wd. It's only when you shift into 4x4 that the front locker would lock up hard enough to be felt. Installed up front, a Powertrax No-Slip locker is silent and undetectable by feel in 2wd. An Aussie or Powertrax Lockright locker up front is undetectable by feel but they can click a little during turns in 2wd... no big deal. Again, it's only when you shift into 4x4 for offroading that they then start acting like a locker but offroad, they're fine.

2) Your second option is to install a Super 35 kit from Superior Axle into your rear Dana 35c. That kit replaces the OE 27 spline axleshafts with hardened 30 spline axleshafts plus it includes a locker, your choice of a Detroit Locker or an air actuated selectable (you can turn it on and off) ARB Air Locker. That makes the Dana 35c strong enough for a locker for up to about the 35" tire size.

Hope this helps.

Front locker only...

Jerry is dead on - good answer.

The (front) Lockright is what I run and has been the best investment.

With the front locker, I ran an open D35c for 6 rides with 33s and eventually 35s - but I babied it 'cause I knew if I pushed it, it would bite me. This combination took me almost everywhere I wanted to go.

I now have a Rubicon D44 rear, so I'm really looking forward to the next ride when I can push hard and try more challenges.

Start with the front locker and see how far it takes you - just don't bounce or thrash on the rear too much - even open, if you catch it wrong, you'll snap the one drive axle.

X2 on listening to Jerry; he is absolutely correct.. I have a Dana 44 and just installed ARBs and gears recently. The Guys at 4wheel parts were adamant that I upgrade to the 30 spline and Chromoly axles in the rear... That is on a Dana 44, so take it for what its worth.

They even made me upgrade the inners of the Front Dana 30 because the stock 27 spline are so prone to breaking!!

Oh! send a little extra and do the job right the first time. if you do not upgrade to 30 spline from the beginning, you will just have to buy another locker when you do eventually upgrade..

.
What size tires are you running? I've got the d44 with 33's, and an ARB and push it pretty hard w/o any issues. I can see maybe upgrading the d30 with chromoly.

For less than $300 and a half day of labor, my D30 aussie locker is by far the best mod to date, and as stated before it is pretty much unnoticed in 4wd.
I used Dave at Northridge
The install is very straight forward with basic tools.
