best locker

2006 KJ · **Posted:** Sat Dec 08, 2007 8:22 pm

I've searched and searched but cant find it. i know this topic has been brought up a few times but i still cant find it. What is the best rear Locker. Not air or electronic.. what is the best lunchbox style locker?? I know a few people have Powertrax.. and some have Detroit tru-trac.. but which one is the best out of all lunchbox lockers? thanks a lot.. even if this is repetitive. it is for a 2006 renny.. so which one would i need it for i believe i have a chrysler 8.25?

DTT is not a locker.. it is a limited slip that stops working when one tire has no traction (e.g. in the the air or on ice).

A locker of course does not perform that way, so it comes down to what kind of driving you do more... on road or off-road... Personally I have the DTT and I love it for it's mixed on-road/off-road advantages, I really wish the auburn ECTED existed for the 8.25 because that's what I wanted.

The only locker that is worth a darn that is not air operated is the Detroit locker,the TT is a LSD but will,and I repeat will stay some what "locked" when one wheel is raised(a little brake action can make it act like a locker).Lunch box lockers are junk in my opinion because you retain the stock carrier which is the weakest part of the diff.The ARB air locker is the best,but any locker/LSD that replaces the carrier is way better then then a lunch box locker.

I run a power trax in the TJ
been that way for a while
not worth a darn for road driving
I get some BAD 1 wheel peel some times
I need to force it to lock if I know I need to go fast from a stop in a turn

Like tjkj2002 said any locker that replaces the stock carrier is better than a lunch box locker
I would not have gone power trax but I busted up the internals in the Trac loc in the dana 44 on my TJ
and by the time I bought the parts to fix it or took the time and effort to put in a new carrier it would have cost to much $$$$
I run 3.73's now if I want to go bigger then a carrier replacement is in order ,break for gears is at 3.73 then a new carrier is needed for 4.10 and up
I dont want new gears now but I do want to drive my jeep so power trax it was

I say stay away unless you must have one
I would go either full Detroit or ARB in the rear of a KJ
If we keep the KJ I will probably go Detroit

so it sounds like the DTT is the best so far.. but if it doesnt keep both wheels moving when one is in the air what's the point of it?? i thought that is why a locker or LSD has a large advantage over an open Diff. does anybody have a powertrax??

^^^^^ something like that (in the link).. sounds pretty good reading about it... but does it actually work?

^^^^^ and is that the DTT that everyone is talking about????

Also after installing the power trax mine failed on the first trail ride
they did replace it under warranty how ever

I learned that the cost of a power trax compared to the cost of a Detroit Locker
along with the down falls of the power trax makes the Detroit look WAY BETTER
the Detroit may cost $125 or so more + another hour labor install ,if you pay to have it done, but worth every dime
I plan to go detroit when I go to 4.56's in the TJ in a few years

The TT is not a locker,it is a LSD that can be made to "act" like a locker with some brake application(mine does anyway),read what a LSD is for and what it does then you'll understand it better.

No,that is the Detroit "soft" locker.
This the TT for the 8.25 rear end----http://www.4wheelparts.com/PDT263600.aspx

Ive never really had any trouble with the powertrax except in the rain. It locks up everytime you pull out which gets annoying quick. It is invisible in the rain if you use full time though.

I would love to get the TT(and may someday) but I cannot do gear work yet so that would be $$ to have it installed.

thanks a lot of the info...

after reading into it more.. the LSD only engages when one wheel has no traction.. soo if a back wheel was in the air.. would the LSD put power to the one still on the ground? or would the back wheel that is in the air just spin like an open diff? also what is the best to do in the frontend.. air locker i'm guessing??

http://www.4wheelparts.com/PDT263644.aspx Tjkj2002- Is that what you meant by the Detroit locker instead of the TT.. how would that act with turning if the rear is Always completely locked?

maybe an air locker front and back would just be the best way to go after all. very costly but i dont think it would fail and it sounds like it would be a much more quality set up..

I have the powertrax no-slip and think its great. Most people that I've installed it for or recommed it think it is good value (meh_kick, towstrap, meducan) Easy to install and road manner are not that bad. Locked vs open is like going from 2wd to 4wd. It makes a huge difference offroad.

I was really expecting something pretty horrible after reading the reviews on the board but decied to give it a try. I figured it was easy to install that if I didn't like it I could take it out and sell it. If you can handle the road manners MT/Rs and a lift then the power-trax no-slip will not bother you one bit.

Strenght is really not much of an issue, especially with a v6 and only 31-32" tires. I've seen the axle shaft on a KJ shear before the locker gave way. However, the locker will break right away if it is not intalled correctly. Eventhough I said it is quite easy to intall, it can be a little tricky making sure everything is lined up. Espeically if it is your first time. It can look pretty much line up but be off. I usually bench assemble them and use a black marker to mark the orientation, so I'm not fumbling inside the differential to align it correctly.

BTW, The only real "luchbox" locker that I would consider for a daily driver is the power-trax no-slip. The others are carrier replacements.

Forgive my newbish ignorance, but...

What exactly is a locker, and do I need one? :oops:

A device which resides in your differential that locks the wheels together so you don't have one tire with full traction, motionless; and the other in the air, spinning uselessly. My guess would be that since you don't know what one is, you don't off-road much and probably have very little "need" for one.

BTW, that link for the Detroit Locker Chyrsler 8.25 states: for use with 27 spline axles, ours have 29 spline axles. Might want to check in to that.

Price is around $400.00 for the Power Trax no- slip, install booklet is included, and no special tools are needed.
No problems with mine in 3 + yrs., and I do have a Detroit True Trac in the front D-30A to compliment the rear Power Trax No-slip.

I'm running a Powertrax, does lock-up in rain and snow around turns if you accelerate like what was stated, mine has worked great off road so far.

2006 KJ · **Posted:** Sun Dec 09, 2007 4:10 pm

great informations.. thanks a lot. i think i'm sold on the power trax no-slip for the rear... KJ04 you have a DTT in the front? does it make on-road driving squirmy at all.. or anything real strange compared to the stock open diff? like the rear sometimes "pops" or "clicks" from what i've read.. does the front do any of that? say you were to do a donut in the snow with your set up.. how would the KJ react? (with the power trax in back and DTT in front) since the front wheels would but cut completely one way.. and no wheels would have traction?

DarbyWalters · **Posted:** Sun Dec 09, 2007 6:06 pm

The DTT comes with a "preload" (2x to 3x) so when a tire is lifted the other tire still turns. You can accentuate this action using some brakes. Of course using brakes hurts other stuff a bit...power. I had the DTT and never had to use the brake trick...it just pulled me thru. DTT front and rear would be a very nice setup...no gimmicks, no cluthes to replace, stronger carrier and fairly inexpensive. The front DTT will cause the steering to be "heavy" when using Full Time on the road...but not that bad.

In 2WD the True Trac doesn't engage, so you don't even know it's there. In 4WD you feel a stiffness in the steering wheel, nothing bad or anoying though, and no noises of any kind.

Woops, hold the boat. Just noticed that you have a manual tranny and the Power Trax is not very partial to them. Your options just narrowed down!

Yes the power-trax no-slip and the manual tranny don't get along so wheel.

*gasp* since i have a manual the powertrax wont be very happy?? how so? and what is the other option.. just get a DTT front and rear?? how do they get along with manuals. if worse comes to worst i guess i could sell my body to science and buy air lockers.. but that's a last resort

best locker
