If the road is leaning it is not a good thing to have automatic lockers. Then you might slide off the road when booth wheel spin. It´s better if one wheel loses traction and the other wheel keeps your Jeep on the road.

I have had no problems with my DL in the snow, but I do think that a DTT would have probably been better, I would say a DTT front and rear.

So if your economical situation alows you to buy a manual locker, that would be better. Why not ARB airlocker while you´re at it...

Is there no LSD in the rear diff?

i have an aussie locker.. locked all the time when power it put to the wheels and unlocks when off the gas. it made my KJ 1000 times better in the snow and ice than it was. before when i couldnt move at a stop sign because one wheel was spinning i'd have to put it in 4wd... now it just goes. having a locker in snow is equivalent to driving in 4wd compared to 2wd... then when you put it in 4wd it is a real tank. i strongly suggest it... and between the 2 choices you gave me i'd say get the detroit locker. tried and true.. wont let you down and you will have outstanding traction. also when the snow is melting/plowed off the road and it is partially bare and partially covered in ice/snow.. the locker keeps traction since one wheel is on the dry.. where an open diff lets the one wheel on the slippery surface spin causing a temporary loss of traction..


i live south south east of the great lakes... several times this winter we had 2 feet of snow... and we always have snow/ice on the roads.

that is my direct experience with a locker in snow/icy conditions

p.s.- everyone told me it would be worse in the snow too... they all must live where it doesnt snow or have no experience with one

So, are you saying if you did it again you would get a DTT in the rear? Or are you saying that in snow and ice it would be better to have the DTT, but you would still go with the DL because of better off-road performance.

From what I hear most of the problems with auto lockers comes from going around corners. On ice less torque = more traction. If you go around a corner and start to slide the best thing to do is throw it in neutral. Powering around the corner will only make it worse (unless you are in under steer and want to 'fish tail' around the corner but the e-brake works well for this). Putting it in neutral will allow the wheels to roll and stop the wheels from sliding and regain some traction. Then you can steer to safety. With an auto locker when you go around a corner the outside wheel unlocks and becomes a free spinning tire. Because it has no torque you have max traction on that wheel. However, the inside wheel now has all the torque. Remember that on ice more torque equals less traction. So if you power that inside tire too much you lose traction on that tire. If the outside tire does not have enough traction either you will fish tail or spin around. So having the locker in will require you to change your driving habits. Does the locker mean you have less traction than a lsd? yes and no. If you go around the corner and throw the vehicle into neutral then you will have max traction around that corner locker or not. But if you are in gear the lsd has the advantage in that it provides power to both wheels around the corner thus spreading the torque out. Essentially the lsd is a compromise between the open (max traction around icy corner) and auto locker (least traction around icy corner).

front and rear ?? with a full-time can i have some problems ?

thanks in advance

I dont think you would have any problems, IIRC there is a member on here who has full-time with a DTT in it

I live in the rockies. I drive on a lot of high altitude roads with lots of snow in the winter. I would not do it with a locker but I guess most who think it's a good idea aren't worried about going off a cliff.

The DTT is where it's at, forget the locker nonsense. The ARB is great because you can shut it off in the snow.
