Default tru-trac vs full detroit

I know the tru-trac is made by detroit and is a gear driven lsd. I am trying to decide between the tru-trac and the full thing. I have had it with the Aussie and I am moving to something more dependable. The Detroit locker is only slightly more than the tru-trac but if it is better than I would much rather get it. I can handle some on road bad manners but how bad are they?

This is from my Mustang background...

The Detroit Locker can withstand more abuse and isn't as civil as the TruTrac. They both are gonna do the same thing, but the Locker is gonna be tougher and louder than the TruTrac.

I decided to go with the TruTrac for my Mustang, but if having the money to spend on something for my Jeep, the Locker would get my money hands down.

I run a detroit in the rear. No issues. It's a little loud once in a blue moon. But no bad driving characteristics about it. Go with Detroit.

Good. I sold my Truetrack about 2 months ago. It was barely better than a open diff and if you lift a tire it was exactly like one. People say you can make them work with a little brake peddle but mine was in the front so that didn't work.

Check out what the black cherokee can do. He runs True-Trac front and back on his dalily driver and climbs over lots of obstacles.

Detroit full case lockers are top of the line. They are stronger and are recommended for tires larger than 33s simply because they are brute. They replace the whole carrier with a series of pins and springs for the locking mechanism whereas the other styles just modify the existing mechanism slightly. I know of no complaints about this locker from many people who have ran all styles of lockers. As for anyone who wants an automatic locker for the front, I would consider a Spartan locker. They're only $230 and they're actually made by Yukon, a trusted name in offroading. Just my 2 cents.

My Locker does not make objectionable noise. You know it's there...but what's wrong with that? You know your engine is there, too.

I can put one rear wheel on loose gravel and the other on pavement and STOMP on the gas pedal from a dead stop: No spin. Nothin' but grip.

Locker's rule.

There's no such thing as an "totally invisible locker" when locked, they occasionally remind u that they are there. My experience with LSDs is "is it working, is it slipping"? U learn to live with locker quirks. I'm with CAEMI.

Nothing I've noticed. The design causes it to unlock whenever one wheel turns faster than the other...like going around a corner.

I've been told that you'll know it's there in the snow but I can't see how having traction will be a problem in snow. I'll find out soon...weather is coming to MI.

Same reason your front end will want to pull to one side on a hill climb with a locker if you stomp on it. You don't have that "sure foot"(the non-spinning wheel) holding the line for you.

It's nothing bad, you just need to know what it would/could do.

TonyB is right...a Locker will pull a bit to the left on dry pavement. It is a sort of torque steer thing but nothing that will endanger you. On a hill climb it might be more pronounced but, still, nothing alarming. It is GEAR driven, not slip clutch so it's not going to let you apply power as smoothly. On the other hand...it works, and clutch type limited slips are not as reliable. I have one in the rear of my F350. It works...but they day will come when the clutches don't grab like they did when new.

If you can justify the money, Lockers are the premium, top-shelf solution. The one in my XJ was there when I bought it. I'll report more after I get some winter exposure with it but, so far, I'm very impressed.
