    Question Trac-Lock limited slip diff

    How important is the Trac-Lock Differential. Is it considered a must-have for off-road use?

    actually, you are wrong. the trash-lok is a piece of ****.i have them front & rear in my wj and they take a lonnnnnnnngggggg time to engage, and once they do, the wheel with the most traction barely spins while the other is still spinning like crazy. they suck... bad option for off road, but i guess it is better than open diff. getta locker or lok-rite or no slip or something else. thats just MHO.

    I would agree for mild off-roading it is a good option, though anything more and you would be better spending money on a lock-right. But we are talking about a Liberty

    Neil said "...next best thing...".

    So, what is it that you know of that is better than Trac-Lok, but not as good as a locker? Just what is it, that outperformes a limited slip, but not as good as a locker? No flaming intended, I'm just wondering?

    Exclamation

    So, the Liberty’s Trac-lock Limited Slip Diff. is actually two items in one? This is not standard equipment on the 4wd-Liberty. If one buys the 4wd version, or any other 4wd Jeep without this option, how well to they perform in off-road driving? Will all 4 tires spin at the same rate when 4lo is engaged? It almost seems plain dumb not to have some type of a locking-limited slip diff. on a 4wd vehicle. Why would this even be an option on a 4wd Jeep?

    The trashloc isn't much better than an open diff. I'd not waste the money and put a real traction aid in the axle.

    If you are asking because you are considering the package for the KJ that includes it, it only makes sense to get it.
    If you already have your Liberty and are wanting some aftermarket traction control device, get a real locker.

    In other words, YES if you don't have your Liberty and NO if you do.

    Thumbs up

    Yes, I'm looking to buy the new Liberty, and the Trac-Loc LSD is offered as an option. It's included in the Off-Road Pkg-$765, or seperate at $285.

    Thanks for all the feedback. It will be included.

    Kind of...but not really. Are those manufacturers of LSDs, or diff lockers?

    I'm only asking because those names all sound like lockers, as opposed to LSDs.

    k, here is how i know: when i have my jeep in 4lo, and my wheel is locked in either direction, the front inside wheel skids. you hear really loud chirps. and in offroad situations, when the wheel without traction is spinning, the other wheel with more traction starts spinning. well, a little. its like the rear wheel. it only spins a little because, well, its a trash lok. they suck ass.

    Not meaning to start a flame war, but it sounds like the problem is not the trac-lok..
    Maybe the tires or
    you have got way to much horse-power

    Trac-lok is not a cure all.. If you are in mud, even with welded together axle, you will spin..
    Is that where you do most of your wheelin.?

    On the rocks, it seems kinda hard to imagine the wheel with more traction is spinning..

    Is it me or did Jeep never put a LSD in a ZJ or WJ from the factory (except for the QD WJ not sure if they had that viscous hunk 'o' crap hydro-loc up front). As far as the trac-loc sucking, sure it does if you're comparing it to a detroit or spool or some other worthy LOCKER. I'll even say it's not as good as an aftermarket limited slip unit. That being said it is a damn sight better than an open differential where you have no chance of giving power to both wheels. I have a trac-loc in the rear of my ZJ with 93K on it and it still works just fine. Sure it's no locker but both wheels spin in any situation and a tad bit of brake even helps it work better. Since you're buying new get the package that ncludes it. Otherwise you'll have to live with an open diff until you decide to dump the $500 plus install for a real locker (read Detroit). Anyway what's $285 in the scheme of a $25K vehicle. I don't see how it can't be worth about 1% of your overall expenditures.

    The trac-lock works great for pulling out a boat or light off roading, If you already have a trac lock ans want to up-grade you can add a Powertrac No-slip , If it is open you can add a No-slip or an ARB , The No-slip works great in ours ,

    Does that replace the limited slip or does it just improve the Trac Lock.

    I'm in a similar situation, trying to decide what to order. I have very little offroad experience and probably won't do much more than a fire road, or drive on the beach. Is the trac-loc beneficial for these types of situations? I'm just concerned about getting the most traction that I can in the sand, some light mud, etc...
