do you want 100% lock up no matter what?
if yes then power trax or Detroit locker

If you want better on road maners then LSD and I would go tru trac
but it will not work as good as a locker

Well how much wheeling do you do? The PowerTrac is a lunchbox locker that you reaplace the spider gears with,has(to some,but not all) terrible on-road manners and will fishtail you on ice.Since it is a lunchbox locker it is no stronger than the open diff.The TT is a gear driven LSD,so no friction modifier is required and has no clutches to wear out an has awesome on-road manners.It replaces the stock carrier so it is much stronger and with a little e-brake can be fooled into "locking" up as a locker will.The PowerTrac is more expensive but can be installed by yourself,the TT is a little cheaper but requires profesional installation making it more expensive overall.My choice would be the TT,but that is my opinion.

Depends on what you do.

Powertrax no-slip will give 100% lock up and untimely be better off-road. On road effects are debatable and depend on the driver. Some hate them, other barely notice it. I notice mine, but it more than livable and it doesn't bother me one bit and is great off-road. It won't fish tail if you understand how it works. I drive mine in the snow all the time. If you feel it start to slip you need to let off the gas, because if you don't it will lock up and then you will really slip and slide. I've seen axle shafts shear before the power-trax gave out so it is more than strong enough for 99% of KJ owners.

If you do just mild to light wheeling and frequently don't have tires off the ground than a tru-trac will do just fine and give better on road manners.

Either one is a big improvement over a open diff just depends on your needs and expectation.

All depends on how much you want to spend. Personally the powertrax lockers are too noisey for me. I've had them in 2 of my toyota pickups i've owned. I liked them but not in my daily driver which my jeep is. They are very effective and they work! But on the street the driveline binds up, tires chirp, it bangs, clunks, jerks and wears the hell out of the tires. The NO-slip may have better road manners but i've never had one. I was gonna go with an Auburn but i just picked up a brand new never installed factory trac lok on ebay for $52. I'm gonna give that a try, should be fine for my application no rock crawling going on here in NJ. Also if you replace the carrier it's alot more involved then just replacing the "guts" like a lunchbox locker does. In my case it doesn't matter i am able to do both. If you are not familiar with setting up ring and pinions and plan on gettig the tru-track you need to factor in professional installation.

There is a big difference between the power-trax lockrite and no-slip. I've had both and the lock-rite was a pretty bad on the road. The no-slip was a vast improvement. I agree though the I would never put a lock-rite in a daily driver.

Just FYI in case anyone doesn't know. There are two power-trax lockers. The power-trax no-slip and the power-trax lock-rite. Lock-rite is cheaper, but definitely has some bad street manners. The no-slip cost more but it a improvment in on road manners.

Once you get used to how the no- slip reacts you shold be fine. Install is simple enough and takes around an hour. Yes, you get directions with it too!

Mine has been in for 2 yrs. and about 15,000 miles with none of the reported noises some have experienced. And yes, it gets wheeled on a regular basis!

Correct i should of made that more clearer both of mine were lock rite's. I had them before the no-slip was even available. They say the no-slip is alot more streetable. I personally have never had one or been in a vehicle with one so really dont know how they react on the street. I can only go by what the other members here say. I know some love them and others hate them. It's personal preference. For my application a lsd is suitable.

Just slightly off topic but has any one put a detroit soft locker in a KJ?
I have driven TJ's with both the detroit and the power trax and the detroit was much smother and quieter on road?

see folks talk power trax up and down but no mention of the detroit wich according to 99% of the guys I wheel with is worth every dime
I am just wandering?

Detroit would be the better choice as far as lockers go as it will strengthen the rear diff. The same is true for the truetrac as it replaces the carrier with a solid sturdy unit. The truetrac and torson are the best lsd in my opinion as they are both gear driven with great lockup. The only advatage to the no slip is if you get one wheel lifted off the ground, but I get around that with my truetrac by appling alittle brake presure. This will cause both wheels to pull together like a true locker. When all the wheels are on the ground, the TT grabs, grunts and goes, it's an awesome unit. I had the no slip in my ranger for 1 week, sold it to my buddy and bought the TT. I like powering in and out of turns, the no slip didn't. The TT is at home in the turns with a slight tire bark every once in a while where as the no slip sounded like it was comming a part. I recomend the truetrac unless you are doing extreme rock crawling, in which case I would get the detroit locker for it's added strength. The no slip isn't bad persay, just bad road manners, noisy and have been known to break as it's no stronger than the diff that it's installed in.

I don't think you need to be doing extreme rock crawling to notice the advantage of a true locker off-road. I find along with lots of other Jeeps that we frequently have a tire off the ground and I don't consider any of the stuff I do extreme. But maybe other people would consider it extreme. I guess it all depends on your definition of extreme.

Never heard of a detroit soft locker. You got any more information on it? I have heard of a detroit locker and I've heard they can be a handful on the road, more so than a no-slip. However the soft locker sounds intresting.

I have had a DTT front and PowerTrax rear on my old 2002 KJ. The DTT acted almost like a locker offroad and the carrier is stronger. I think a great combo for the KJ is a DTT front and rear.

If you have Selec-Trac 4WD, the front steering will be "stiffer" when in Full-Time 4WD. With Command-Trac you will notice no difference on road basically.

What I ment by extreme rock crawling is if you find yourself with one tire lifted off the ground more than all 4 are on the ground. In that case it would get old appling brake presure constantly, might as well just get a detroit locker. For most situations I find that the truetrac does an awesome job and very capable, it's a hair away from being a locker. A locker will give you a full 50/50 split between the rear wheels where as the TT will be a 30/70 or a 60/40 whatever the torque demands are, but there's still power going to both wheels like a locker when slipage occures. The tire doesn't even make a full revolution before the other wheel kicks in, maybe a 1/4 if that. I know I sound like I work for truetrac or something, but I'm really impressed with this unit. After having trac locks and even the no slip, the TT does so many things well, it's hard not to sing it's praises. I was just so surprised that a unit can operate so well offroad, but yet be so gentle on the road.

i have used the powertrax noslip and didnt like it with my 5-speed. it made it shift horrible. i now have the auburn and it is great! As far as traction goes on a scale to 1 and 10 the power trax is a 10 but the auburn is a 8.5 and has perfect road manners.

Tru Trac or Powertrax
