Recommended? Yes

Comments: Didn't know I had it till I changed the diff oil. Seems to work good on the trail.

Price: $175.00
Pros: doesnt eat up my tires on the pavement....
Cons: none yet
Recommended? Yes

Comments: just got it it put in cuz my stock carrier and gears were toast. i bought an axle from junkyard to use internals and found that it had trac loc in it..... so it was kind of a surprise upgrade when i redid my gears.. i havent really had a chance to test it good but i drive on the highway to work and is a constant dd while also my toy so cant lock it alll the way and this works good so far...

Price: $129.00
Pros: Fits a variety of applications using Dana Spicer axles and diffs.
Cons: Useless, barely engages, clutch packs wear out.
Recommended? No

Comments: I installed a new one 7 years ago in my XJ (Dana trac-lok) and a detroit true-trac in the front. I wish I hadn't even wasted the money on it as it is useless, even from the beginning when the clutch packs were new. The true trac does all the work. I'm not sure I've even seen both tires spin with this LSD on gravel. I would rather run an open diff than put this thing in again.

Price: $220.00
Pros: The trac lok is an awesome limited slip. A little pull on the emergency brake in the snow or mud and it practically locks itself. Smooth operation, and just as good as a Detroit true Trac
Cons: IT LOVES THE LIMITED SLIP ADDITITVE!!!! ($$$)
Recommended? Yes

Comments: Great Factory Limited Slip id say. and no side effects of a locker, but almost as good with the right throttle play

Price: $1.00
Pros: came in stock! helped when i needed it (hanging a tire)
Cons: none
Recommended? Yes

Comments: it camestock, so i cant say anything bad about it. if i ever wanted to get a new locker, selling it would make a lil money

Price: $100.00
Pros: it works!! both tires spin. Rooster tails on gravel roads.
Cons: definitely gives more torque to one side, but barely
Recommended? Yes

Comments: I got this LSD axle for free, because I helped a friend transfer his built up lift onto another Jeep shell. That shell was on supposedly "junk" axles, when he bought it. We took the axles off and noticed that the rear tires spun the same direction, after pulling the cover, I realized it was posi!! I bolted the feller up and Its been working out great. I definitely have more grip in slippery conditions. I would highly recommend this, if you can find a cheap one. Jys tend to charge too much for axles nowadays.

Comments: Better than nothing, I don't care what you guys say!

Pros: Automatic action, OEM
Cons: Consumable parts (friction materials)
Recommended? Yes

Comments: I have a fresh rebuilt D44 with 3.73's and trac-loc in the rear end of my Jeep. Not too sure the friction materials will stay together for that long, but I am happy with the performance of it. Very nice to have. Spins awesome donuts
