Great if you are off-roading. Not feasible for highway use and it makes for difficult driving on rain soaked roads. Some are even noisy as crap.

Detroit in the back is great for all situations except maybe pulling a mega trailer while turning tight corners under power. All the guy's I've talked to who have it in their trucks love em. Those who don't, don't. I pull 11k in the summer and never had a problem, Have 6k of sand all winter in the back so I don't see many negatives...No noise at all.
I'm a traction freak so I also have a lock right in front. I do 50 mph in 4x4 and no problems. As far as rain soaked roads they are great cause the inside tire won't light up you just go forward...Ice traction no comparison, Snow traction no comparison, need to know how to drive priceless...

I agree with 99f350sd. When i put in a locker its either going to be the detroit locker or detroit tru-trac.

if u want a locker put it in the front..

then u only use it when ur in need and it makes the truck infinetly more drivable on teh street..

unless u go air/electric locker in the rear of course.

but i've always found a front locker will help u more often then a rear..

I went through this whole debate about 3 weeks ago and decided on a TrueTrac for the back. I'll add and E-locker to the front when funds are available. I'm on road 99% of the time, so a detroit locker just didn't make sense. Either TrueTrac or one of the switchable lockers.

I'm on the road most of the time and a detroit is the one to get hands down.. lets see you move over to the side of the road your right tire is on ice you go to pull out into traffic and no go. But wait a minute I just spent big bucks on a trueTrac!!! Get the picture. If you don't need one don't get one stay open. I guess I just don't understand I keep tellin you guy's they don't make any noise they just work like you want everything else to work..

I guess that makes my mind up on either the truetrac or detroit. looks like the detroit is the way for me.

A TrueTrac does not slip like he described, it is a very good LS for up to 37" tires. Also, if you drive on ice often, the TrueTrac has a lot more predictable operation, the Locker will get squirrely on you.

Flutter the brake, the True Trac starts splitting torque and away you go, ice or no ice. I guess I just don't understand I keep tellin you guy's... A True Trac isn't a locker, for sure, doesn't split the torque 50/50, however, even on ice, even with one wheel in the air you just need a little resistance, which a few clicks of the e-brake, or tapping the brakes gives it and all of the sudden both wheels are turning. The True Trac kicks *ss for those that don't need a full locker, on road or off (again, if you don't need a full locker off road).

I here what you are saying but why on earth would you want to mess with all that when they make a unit that does it all. Its not any more unpredictable than a good LS on ice and snow. Heck you punch an open rear on ice and you are going sideways whats the point you have to learn how to drive sometime. I took the plunge and I'm telling all the guy's on here The detroit locker for the rear of superduty trucks is the way to go. There are some things you may not like about them! For instance When you put the truck in park it will roll 8 inches or so....no biggie. you might not want to power around corners,,even with a LS you will wear the inner tire. No biggie either
Noise, Nothing seemless operation.Strongest diff made. I think you can get them for about the same price. Heck if they made one for the front of my 99 I would have one in there also the lockright is noisey..

You didn't explain what you want to accomplish so it's a little difficult to make a recommendation. I have an '02 Ex with ARB selectable lockers front and rear. I have used them in sand dunes, deep snow, hill climbing, and on icy roads (trying to get moving, not driving) and I love them. When I unlock I have a standard open diff. My Ex tows a 10K toybox 90+% of the time and I have no problem because I unlock them on dry pavement. From my experience if I could only afford one I would put it in the front.

The down side is you need an onboard compressor to lock them, you need to run air lines and when the front is locked it under steers. But the switch is easy to reach and I unlock as soon as I can for turning.

I had them installed when I was regearing so the install cost was negligible.
