Thinking about getting front and rear lockers. This is my daily driver with weekend fun thrown in a few times a year. Would the DTT for the front be fine with the selectrac? I read in an older post it might cause issues with full time that I use in bad weather (flooded roads, snow, etc.) but other posts said its fine. I might be wrong but I think with the DTT in the front it would kinda be like being in full time all the time even if in 2wd? For the rear, would I be better suited with another DTT or go for the DL? Any and all advise/comments are appreciated

I run a DTT front and rear but do not have selectrac in two of my KJs that run them
So since you are one of those folks who think they need to run it in full time , then yes given the right circumstances " it may " cause some issues
Not knowing exactly how you drive etc , its hard to say 100 per cent
But with the DTTs most times you have to sort of set up the DTTs to work , so normal driving 99 per cent of the time I don't think you would notice it
For me when I know I am going to need the lockers , I press the brakes while giving some gas and it will ( to put it in common terms ) set the lockers up

In my CRD Liberty (Only available with Selectrac) I ran a DTT upfront. I had no issues with it. In 2wd you will not notice it is there.
For the rear it really depends on what you want to do with your Jeep.
I have DTT front and rear and really like them. They are passive, and engage when you need them.

Thanks 65Corvair

Never ran DTTs in a selectrac so was just going on what a buddy who did have both stated
Plus always go on the side of caution in telling someone that it may or may not work and not knowing how they use them or of they do know how to use

Hello Tom. I will be installing a DTT in the rear of my Liberty in the next couple of weeks. Any recommendation on what viscosity gear oil to run in the DTT? This is a 5 speed manual 4x4 that see moderate trails from time to time. Thanks.

I run 85/90-140 in all of mine , but they also get used for towing a good bit as well

I have select trac and dtt up front and e locker in rear. If I were to do again, just dtt all way round - like Tom. The dtt is that good.

But, I did/do notice some differences with front dtt. Even in 2wd in tight turns aka U turns or parking lot maneuvers you’ll hear tire scrubbing due to the bias. Going down highway, you’ll find that it tracks more with the road crown. And the steering wheel is a little heavier and likes to return faster. In ft 4wd you’ll feel an even stronger heavier wheel and tracking down highway. Not significant but noticeable if you pay attention.

I installed rear E locker before front dtt, and the front dtt made a bigger difference in off-road capability. It’s also seamless and works wonderfully.

I run synthetic 75-90 in my dtt which is not recommended by Detroit because it reduces bias. In the front end, not a bad thing and I haven’t had any issues.
