Locker question

I'm looking at getting a powertrax no-slip locker for my cj5. I was wondering if anyone with a cj5 has had any experience with them. How does it handle on the road witih the very short wheelbase? I do quite a bit of cruising on the road along with my off-roading and don't want something thats going to make it dangerous, but the "sales pitch" says it is very streetable.

I've got a Detroit Softlocker in the back of mine, so they have similar operation characteristics. There was a night and day difference going from open to an auto locker in the rear. The short wheelbase of the CJ-5 amplifies it that much more.

In a straight line you don't know it's there but when you corner you need to make a decision....keep at a constant speed, accelerate through the corner or coast through and get on the gas when you straighten out. If you get on or off the gas in a corner the locker will lock/unlock and cause the back end to shimmy. This can range from barely noticeable to full on heart attack inducing depending on severity of the corner and road speed. As long as you pay attention, it's not too bad though. You just need to learn to drive all over again, :-).

Winter is another story all together. As soon as the roads get packed snow and ice I have to put it in 4wd or I just spin out around almost every corner no matter how slow I'm going. Freeway travelling is almost out of the question. Nothing quite like your back end trying to come around at 55 mph on the ice. The traction off-road in the deep snow is simply amazing though.

If you actually take the time to get used to it they are not too bad. I've been driving my Jeep almost daily since the weather got nice and barely notice it anymore. The Jeep is seeing less and less time driving around town though. If you have the money a selectable locker really is the way to go. You get the on road handling of an open diff and the performance of a full locker when you need it. If you are going to do a lot of street driving I would really consider one.

Just installed the no-slip locker in my CJ7. Had a Detroit EZ locker in the past. The no-slip is very quiet and handles much better.
Don't know why but it is good cornering also.
Parts look the same except for some added springs.
Not sure about winter driving yet.

I've had the No-slip for at least 6 years and love it. Mine is not a DD but I do drive it around on nice days. At first it will give you a sense of somethings wrong but you will not notice it after awhile. You will get some tire chirp once in awhile, but you will learn to drive with it in a short time. I also put one in the front and like it just as much! As KrazyGimp said, it will scare the hell out of you in the snow or ice, ALWAYS use 4WD in the slippery stuff!

Well, from my research I think the no-slip is the way to go. One more question though, I've heard that the AMC 20 is not as strong as some other differentials. Will installing this locker increase my chances of breaking something? I don't do any crazy off-roading. no lift, 31" tires. Just some simple hills, mud, etc. On road in nice days and in the snow to get to work.
Also, from some of you that have it installed, does it increase the slack in the driveline?

from what i understand with simple upgrades the amc 20 is as strong as say a dana 44. basically one piece axle shafts, and get the tubes welded and trussed. i did do the one piece axles i think from crown.

i don't think you really have much to worry about though.
