Which would you pick for light to moderate off roading and street use in a rear axle? Or other suggestions? No air or electric engaged lockers please.

Any of them are good..... really depends on your preference or price. I'd go with Aussie or Detroit personally
 
I have experience with nearly all of those types. Given those choices the easy pick for me is the Detroit Trutrac. I prefer this over the others because it doesnt use clutches while offering posi. It performs very good on/offroad. It doesnt require a gear additive either. I used the TruTrac on a Baja truck for several years in order to reduce the use of 4wd in the desert.

The Aussie, Spartan, detroit, and grizzly are basically the same. None of them use clutch packs. The Aussie and Spartan are the simplest of the bunch and the easiest to install. The eaton is the only "clutch pack" posi he listed.
For simplicity, I think the Aussie is the best choice (I don't like Spartans install process of not using shims).
The Detroit is twice the cost of the Aussie without being 2x the product.

I have had both the detroit Truetrac and the Richmond/Lock Right Powertrax...
The Truetrac is really good if you do offroading occaisonally, you can really feel the added traction over stock and is very easy to live with on road.
The Powertrax is in my opinion a great offroad option. It is fully locked when going straight and unlocks in a turn. Traction off road is just as good as my electric locker. It automatically unlocks in a turn on high traction surfaces which makes it good for on road although if you gas it hard in a turn on road you will feel it lock up. It will also sometimes make a click or pop sound when it unlocks. In my opinion, I would go for the Powertrax over a Truetrac. They are cheap and easy and fully lock up.
Up to you, what ever it is you choose will surely be an upgrade from an open dif.
 
Where can one buy the Aussie? They're sold out nationwide.
 
Bumping this, as i want to lock my front end before i regear but don’t have part time 4x nor enough money to buy a e-locker or air locker.

I have a freiend with the truetrac in his jeep front diff and loves it! But here i read they're not all that. He rock crawls the s*** out of his, i would be more of a trail, small rock and sand kinda guy. I plan on getting part time but may be a long time from now, but i need to gear mine now.

I read on their website that whatever gets more traction gets more power, the opposite of an open diff. If i get a tire off the ground it will get no power and the other tire will get power. Is this wrong?

Anyways, i see it’s kind of a limited slip, not a locker and wont be quite as good, but better than open. What says mud? Waste of money or good enough for me?
 
The problem with our vehicles is they are full time AWD/4WD. Even with a Center diff that torque splits I don't think you can run a Aussie/ Spartan in the front without some serious issues, but I could be wrong. If you could disengage the front then no problem running the Spartan or Aussie.
 
Spartan for over 30k miles no issues to date. And I know people are getting very tired of hearing this story. I did have one situation where a rear locker that I couldn't unlock was fairly dangerous. That was a slick off camber spot. The rear end locked and the truck just continued to slide sideways no matter what I did, I was alone, and there was nothing around to pull cable to, and the drop was a couple hundred feet. I was so close to the edge on the driver's side I had to exit the vehicle through the passenger door to assess. I came about as close as I ever have to losing the truck I think. lol.

Why do you need more than an open diff for moderate wheeling if the rear is locked? It’s a total waste of money. That was the right answer for the OP of this thread - you don’t need lockers for light to moderate wheeling.

I have run a TruTrac with AWD and a rear Detroit. It is an awesome combo in winter weather, but nowhere near a front locker.

Once one tire loses traction completely, it can no longer bias torque to the other side - all limited slips fail when you need them the most.

But unless you are doing serious rock crawling trail work there’s no reason to do anything with the front diff.

If you really feel the need anyway, do the TruTrac. A locker is total overkill and the TruTrac balances extremly well with AWD and rear auto locker for dry and wet road use and they aren’t useless off-road. It might do well enough in sand.

But again, it’s nowhere near being triple locked.

Sand, mud and snow. I am usually very remote and alone. I have a winch but there is not always something you can winch to. As i see it, its 400 for something that can help. If I decide i need something later, it’ll cost me a lot more than that. I will at some point end up rock crawling some, it may be my only option on a trail that i am on. I just don’t steer for the rocks.
