I tested out my front and rear Detroit Truetrac LSDs

And they work, or I should say "it" worked, as I was in 2wd the whole time. Not last Saturday, but the one before, I did a trail called Montana Mountain. It has steep loose climbs, and the rear Truetrac made a huge difference.

I did this trail about 10 years ago, and it was noticably easier then, and I needed 4wd to climb some spots with a Traclok that was probably worn, and a front open diff. With the Truetracs, I purposely left it in 2wd, and climbed it with relative ease.

Ok, they aren't for the hardcore rock crawler, but they are light years ahead of open diffs for those that aren't typically lifting tires off of the ground, and the Jeep drives like it has open diffs on the street.

Sounds like you like them in that case? That's good news. I've never driven a vehicle with lunchbox lockers, only selectable lockers, so I have yet to experience them.

It drives completely like open diffs on the street, but if you aren't lifting tires off the ground, it seems just like a locker with power to both tires on the same axle.

In my honest opinion, if one isn't really rock crawling, and lifting tires off the ground, a Truetrac is awesome. It just doesn't sound as cool as saying you have "lockers". If one needs lockers, get them, if you really don't...don't.

I didn't use the word "locker" in the thread title, but it is there now (Chris maybe did?). Someone will try and correct me for calling them that, but I didn't.

I have truetrac's front/rear and absolutely love them!! Learn how to use the brakes to get them to act very much like a locking diff! I have had only 2 tires on the ground, climbing rocks, and with just a little brake and gas work I didn't even hiccup!

Did you do the install yourself? I'd love to throw one in my Dana 44 before installing the new to me axle.

Just keep in mind people that Truetracs are not lockers. Understand what you need before you decide on lockers or limited slip differentials. They are VASTLY different and rarely will one work well when the other would have been the best choice.

Jerry, I understand they are not lockers, but they should not be overlooked or underestimated for their ability to perform very well even in a situation where a locker is "required". With good driving techniques it will far outperform any other limited slip out there and achieve almost a locker capabilities. (Look up some of the military training videos from how to use the brake technique) And (IMO) for the price it is a damn good option.

I'll be replacing my Traclok with a TT next month. Good to hear good results with your TT. I like the fact that you install it and forget about it. No hoses, wires, or cables to damage. No air leaks or solenoids to worry about failing. No clicks, pops, or funky handling behavior to get used to. Just simple traction when you need it.
Here's a good video explaining the differences in the different traction devices available to our hobby.

I've been in several occasions where my Rubicon LSD (similar to a TT) made it through an area where an open diff didn't. There is most certainly an advantage with a TT over open diffs as long as a tire doesn't get too light on the ground.

I thought Rubicons have true lockers? Or...am I mistaken, or are you talking about something different?
