Need a Locker Lsd Or auto locker?

[Kurtis]

I need a locker for the rear my 85 60. An arb is pretty much out of the question at the moment.

What are the performance differences of a Limitied slip such as powertrax no slip compared with the locright autolocker?

What are good brands for each?

I don't understand the difference between the lsd and the autolocker. I understand on road the lsd would be much better noise wise and clunking, but offroad is there any disadvantage or is it just a little more expensive?

Does anyone have the powertrax no slip? if so how does it do on/ off. I searched and only saw a couple of opinions.


Thanks,

If you use it as a daily driver then definately go with the LSD in the rear. Noise is not so much an issue as drivability. You can always put an auto locker in the front as long as you take it easy on rock climes. The sudden locking can snap CV's easily.

I have the powertraxx in the rear diffierential on my truck. It works very good off road. On the poavemett it wants to lock especially on concrete in slow speed turns like on a driveway or parking lot. Also going up a steep grade with switchbackes in the rain...you had better slow down. I think it would be "hairy" on ice or slick snow not driven my cruiser on either since the install and we don't see that much of that kind of weather here in AL. I'm going to take mine out. I would say its a great tool for off-road. On the road its not so civilized, you 'll have to get into the habit of pulling into the drive way and making slow speed turns with the clutch pedal pressed in. It will certainly engage the rear tires, but you'll have to adjust your driving habits on the road. I'm going to try some Auburn LSD's on mine.

Slow speed turns is where the locker will get your attention on the pavement. I suspect it would also get your attention on ice. Also will annoy you on shifts sometimes, as the locker "bumps" when shifting sometimes. If you off-road alot I would go with the power-trax or other locker and live with the bad habits on the pavement. I would want to see what it acting like in the snow and ice if you see a lot of that where you live, because I think it could potentially be dangerous. Given certain situations the locker will engage on a down hill slope (downshifting) and it does work in reverse too. Hell of a tool for off-road.

I'm guessing with an auto trans a locker may not be as noticable.... with a manual it certainly is.

I run an Aussie locker in the back of my 80. It preforms great off-road, K.I.S.S. right. On the pavement I never notice it. Sometimes when I have the windows down and am going real slow, I do hear the tick, tick, tick, but that is it. On the longer wheelbase trucks, like ours, on road is not really affected as much as the 40s. Just my $.02.

Just read Elbert's post, ice and snow may be a different story and a manual tranny too. Sorry for butting in.

Thanks,

The No slip and the Lockright come from the same company (both are powertrax made by Richmond gear). The No slip (more $$) has a camming mechanism in it to make it a little smoother than the standard lockright but both are auto lockers. I had a No slip in my last rig (not a landcruiser) up front and rarely I got any clunking (really only had it engaged by locking the front hubs when I was wheeling). A true LSD (limited slip differential) allows tire slippage and does not allow the axles to be locked together. A LSD is a compromise between and open diff and a locked diff and is generally better for majority on-road driving with the need for better traction off-road than an open diff. An auto locker will offer better traction off road than an LSD because it locks the axles together but can cause some handling issues on-road if you refuse to accomodate for the auto locker in your driving style, which generally means to slack up off the throttle when going around corners. A locker performs better off road because the two tires will spin the same speed while under load (got your foot on the gas) no matter if the tire is on the ground or in the air. A LSD will still allow the tire with the least amount of traction to get more of the power but will divert some of that power to the tire with some traction depending on the biasing of the LSD unit. Some LSD, particularly the ones that use clutch packs wear out and offer the same traction that an open diff would when wheeling. Generally those who wheel are willing to sacrifice some handling adjustment on-road for the superior traction gained when off-road.

The favorite, cheap auto locker many of us run is the aussie locker. The strongest auto locker would be the detroit but requires setting up gears because it replaces the carrier. Detroit also make an auto locker (called true track I believe) much like the lockright or the aussie locker that simply replaces your spider gears in your carrier.

I have the lockright and I love that damn thing. Of course it is in a 62 . It was a trick on ice for about a day after that it was quite helpful even on ice and snow. As a matter of fact the last 2 winters I have only had my four wheel drive engaged once or twice.....did not need the front wheels...but then again it was a auto.

So the Powertrax no slip is actually an auto locker also not true lsd? It seems like a good choice then if it doesn't clunk or effect on road driving as much. So I guess my choice now is between the power trax no slip and an aussi locker.

Of these two which gets better traction off road and which is quieter on the road?

With the powertrax no slip give the same perfermance as a autolocker offroad?

That's correct. No Slip is an auto locker. It's suppose to be smoother at engagement/disengagement than the lockright because of the camming device but will have similar handling characterisits so there will be some learning to drive with it on-road (IMO not a big deal and well worth it for the gains offroad). Both the aussie and No slip will perform the same task and traction will be limited to the kind of tires and terrain you run. Set up is important and can affect the way the locker handles so don't just slap it in there, measure and test like the manual says. You can read the manual online (at least for the aussie) to understand how to set it up.

I think it would be "hairy" on ice or slick snow

Lots of posts in the 40/60/80's forums re auto lockers. I tried to read them all , trying to understand the winter implications. I want to improve my 4 wheel capability, but not w/a large negative impact on winter driving. Consensus is that a long wheelbase rig like the 60 is fine (maybe even better) in winter with an autolocker. Many of the alaska guys run them, also a bunch in CO and UT. Based on this input, I installed a locrite about one month ago.

Excellent choice

I wish they made the Truetrac (worm gear-driven LSD) for 60/62 axles. I've talked to a couple guys who have them in their muscle cars and they can't say enough good things about 'em.

You're right, truetrac is not the name of the detroit auto locker that I was thinking of. I can't seem to find it on google so maybe they don't sell it anymore, but it looked just like a lockright.

 

[boots4]

Found it, it was called the E-Z locker (like the lockright/aussie) by tractech who also does the famous detroit locker.

I can get a loc right pretty reasonable, fourwheel parts even has 15% off a lot of lockers including powertraxx.
Is the no slip a lot better than the loc right as far as noise and on road drivability?
Basically is it worth the extra 150$ ?
I've been piecing away at this one for about 7 months and after having it out quite a bit I defiantly think it needs a locker.

.

I have never driven a truck with the no slip in it. But, based on the extensive info I read on this forum, I got the loc right. Off-road they work the same, on-road there's a difference, but in a 20+ yr old truck, there are lots of places to put an "extra" $150, and I decided not to put it there.

I think if you go with the loc-rite you'll be super happy. Don't over think it like I did.
