I have a 2wd 95 nissan pickup. I have been thinking about putting a locking (push button from in cab, most likely electronic) or limited slip differential in it and wanted to get the green screen opinions about which is better. I do 85% roads and 15% dirt roads and ranch roads. I am looking for it to help on muddy road conditions or during the winter for better traction on wet/icy/snowy roads. Bhat are the benifits and downfalls of each one. Also I have only found one limited slip diff for the truck to the tune of $500 bucks. Would a junk yard be a good place to find either one? Thanks alot for the help.

I had selectable air lockers in my jeep front and rear. I have an automatic locker in the rear on my Silverado. I've been through some pretty crazy stuff without using my lockers, and only use them if I couldn't get through it in 4WD alone, but with 2WD I'd say a locker is a better route than an LSD. Check out the Eaton E-locker for electronic lockers. They've proven themselves in the jeep world. Air lockers are nice but expensive, and you probably won't be straining the locker that hard. I've seen E lockers hold up to some serious abuse.Comment

is the air locker a limited slip or true locking diff? What are the benifits of it? ThanksComment

I ran a Detroit Locker in the rear and a Truetrac in the front on my Jeep.. it would go almost anywhere I pointed it..

ARB Air Locker! Hands down! I put one in my 86 4Runner for rock crawling and I would go until I couldn't go any more. Then I would push the button and crawl out of every situation. I can honestly say that I never got stuck with the locker engaged.
Oh....and another plus in having the Air Locker is that when you are on wet pavement, you don't have the rear locked. With full lockers your truck will get butt loose much easier.Last edited by Mudshack; 02-08-2011, 01:43 PM.Comment

A limited slip would likely have a little better turning radius and would probably be ok if you had a 4 wheel drive. Since it's only 2 wheel drive I would go with the locking diff to get you through the mud better. That being said, there is still a good chance you are going to get stuck if you hit any deep mud since you don't have a working front end to pull you through it. If you are really that worried about it then I think the best option would be to sell the 2 wheel drive and get a 4 wheel drive truck.Comment

I am not too worried about going through to deep of stuff. I am just looking to get get a little better traction when I need it. With grad school and funds being the way they are a 4WD truck is not really an option at this point. One day though... Thanks for the imput and keep it coming please. Also how hard are they to install myself?Comment

Powertrax makes a "NoSlip" locker, they are reasonable in cost and can be installed on your own if you are mechanically inclined. Powertrax technicians install them at car shows in 5 minutes, for me, it might take 5 hours. Upside is cost, downside is your rear end is always locked, it will give around turns and supposedly be quiet when compared to other full time lockers. For me, a full time locker in the back means adjusting driving style slightly to compensate, especially during low traction conditions.Comment

The E locker is definately a nice unit. And, a great unit for mid $700 plus installation.Comment

selectable locker for sure. theres a reason offroaders remove the factory limited slips and install selectables.
Limited slip wears out. its clutch plates rubbing on each other. your difference in wheel speed has to reach a specific value, somewhere around 700 rpm usually. so you have to start to get stuck and spin one wheel before the clutches start to engage.
a full time locker (spool) is super cheap but not streatable. you will chirp the tires on pavement everytime you make a turn.Comment

Air lock diff if you did more off roading i would go with the limited slip but since your mostly on the street stick with the on off switchComment
