Rear locker or both?

You just have to set down your latte long enough to push the button.

Good point. Actually, traction-control works like posi in many ways. I wonder if they would aid each other or fight each other. Would be nice if somebody on the forum chimed in who might have put a posi on their rig.

I've never heard of anyone adding posi to a 4WD vehicle. Only lockers and limited slip. Isn't posi more for hot rods?

I believe positraction is a trade name for limited slip....maybe GM calls it that?

Edit: confirmed...it is the GM trade name for limited slip.

Yeah... I think posi might have been a GM thing then inside GM -- a Pontiac thing for the muscle cars.

But Yep... I am talking about standard limited-slip diff.

Particularly for those of that are on the older side of life, we remember when 'posi' quickly became a generic term for all limited slip axles, despite the manufacturer. Its just easier to say and everyone knows what you mean. Kind of like Kleenex, Xerox, Q-tip, etc.

Ok, that makes sense.

My understanding is that a locker is better for rock crawling. An LSD is better for most other things such as rain and snow.

Though if you're driving in thick snow (unplowed road), a locker might be better.

If you watch Matt's Off-road Recovery on YouTube, he has limited slip on the rear axle of his Jeep Cherokee, The Banana, and he swears by it. It certainly is a very capable Jeep....but I'm sure at times there is the magic of video editing at work.

Jeep Cherokees are incredibly capable.
