Limited Slip Question
#1
So I have a 2010 STX 4x4. My axle code is 26 and I'm pretty sure that's a 3.73 gear ratio and I know for a fact it's non limited slip. I had a limited slip on my last truck and I'm kind of missing it to be honest, I can feel that one tire slipping all the time, how much would it cost me to get a limited slip? I also have 35 inch tires on my truck, should I change gear ratios aswell? Do they make a 4.10 limited slip? Granted my truck has the 4-speed trans and I only pull a small trailer from time to time. If not I really don't mind the 3.73, it does pretty good even with my big tires. I just kinda wanted a limited slip rear again. If I have this all wrong and I'm stuck with what I have, it's okay I guess. If I get stuck I can always throw it in 4x4.
Thanks Guys

Yes the 2 designates open diff.
You can get one, I would recommend a detroit tru trac, one of the best LS out there. You could also find a factory LS carrier and swap it too.
You can check junkyards, and might find a 4.10 w/ Elocker, or LS as well and jut swap the axle out.

Detroit Eaton true trac cost is $600 and new carrier bearings about $90 plus install. I think the own limited slip is around $500 plus bearings and install. As far as gears 4.10 from 3.73 wouldn't make much of a difference for the cost(parts are $800-$1000 plus labor). If you want lower gears jump to 4.56. I have 4.10 with 33" tires and a level and it's about perfect. Factory LS use clutch packs that are designed to wear out, True Trac is a torsen type not designed to wear out and doesn't require friction modifier, but it requires conventional non-synthetic gear oil which in the weight our rearend requires can be hard to find sometimes.

So is the Detroit LS similar in function to the factory LS? What is required for it? Do I have to buy a whole new axle? Re-gearing may not be in the budget but the LS is definitely something I am going to look in to.

Definitely go with a Truetrac. I ran one in my 03 Excursion with 37's and it never had any issues.
Like cmbowles25 said, it's just the Truetrac, install kit (bearings/sleeves/gasket) diff oil, friction modifier and install.

I'm looking in to it and I can't seem to find the one I need, it only shows the Truetrac being offered for ford half ton pickups up to 2008. I need some help here. haha

True trac (assuming you have 9.75 axle)

If you do go this route DO NOT use friction modifier and be sure to use NON-synthetic gear oil. If you read the manual that comes with it it'll explain all that. It's up to you to just replace carrier bearings or use a minor install kit.

Why would you want to replace an e-locker with a true-trac? Replacing OEM LSD with true-trac makes tons of sense. Or is the factory e-locker not very reliable?
OP I would stay away from clutch pack type LS rears, like the OEM style. Go with a True-trac like everyone says, or you could do a lunch box locker like a lock-right.
