A limited slip aka posi trac (chevy term) differential aka diff senses when your tires are 'slipping' more than they should for turning, and lock the wheels together, forcing them both to turn, putting more power to the pavement and letting your car accelerate faster, or helping you get out of a ditch or mud hole, the old style rear differentials were well know to leave you stranded in ditches and mud because which ever wheel had less traction would spin, and the one that had traction would 'slip', leaving you stuck. hope this helped with your question.

Does a 1995 z28 have posi trac?
If you mean "limited-slip", yes
How do you build a posi trac?
You buy a posi-trac rear differential.
What type of additive is required for the trac lok jeep limited slip differential?
The limited slip and Trac loc differentials require what Jeep and Chrysler sell as limited slip additive.
Does the 05 ram quad cab hemi have posi trac or limited slip rear end?
Limited slip was an available option.Limited slip was an available option.
What is ford trac-lok?
That's Fords name for their limited slip differential
How do you change your 1988 samurai to a posi-trac rear end?
You can change the rear end of a 1988 Suzuki Samurai to Posi-trac by opening the differential and removing the existing ring and pinion gears. The Posi-trac assembly is then install and the gears put back in place.
How can I tell if my differential is a posi trac?
Jack one side of the car until the tire is free to turn. If it will not rotate with the trans in neutral (brakes released), the differential is a (sure grip) (limited slip). If the wheel rotates it indicates an 'open' differential..Jack one side of the car until the tire is free to turn.

What is no-spin axle?
It means that when you get the rear wheels stuck in mud or snow or something, when you have the vehicle in gear and try to move, the rear wheels get equal power so even if one wheel is free, it won't spin. Other names for the same thing is posi trac, or limited slip differential.
Pathfinder posi trac?
my 95 is posi !!
Did a 1995 Chevy Silverado z71 have posi-trac?
Yes, it could be ordered with GM's Posi-Trac as an option.
How can you tell the difference between positive traction and limited slip traction?
Here's the difference, correct me if I'm wrong. Posi- positive locking differential. Like (lock right). Actual physical meshing of metal pieces, using spider gears that are spring loaded. Which will override in turns and click to allow wheel speed difference, and fully lock and mesh on straight aways allowing full power to both wheels. Lsd- limited slip differential. uses clutches and medal plates with springs, when wheel speed differs, spider gears will override and springs will expand allowing clutches to not rub on one another to smoothen out the power from one wheel to the other. When on straight away, springs will shut, and clutches lock with metal plates allowing power to both wheels. kinda like the clutch and pressure plate in a trani. that's what 8.8 traction locks are. there's also worm gear set ups like the true trac, and wave trac. which are like Lsd, but uses worm gears to do the same thing. Actually limited slip and posi trac are the same thing but to tell the difference between a normal rear end and a posi is to raise the rear end and turn the driveshaft. A normal rear end will rotate one wheel forward and one backwards, on a posi both will turn forward. Positive traction or posi trac is just a generalized term for a limited slip differential and refers to a GM model. Other manufacturers make a limited slip rear differential as well. Actually they are not the same. Posi Trac for example in a 1971 Mustang Mach 1 has gears in the rear end that lock up both output shafts, where as a limited slip rear end has a clutch pack that helps to turn each wheel at the same speed but due to clutch slip they will not spin the same. Posi is better for straight shots and mudding so both tires will spin the same no matter what, which makes turning difficult due the the fact the rear tires will fight because of turning radius. Limited slip allows the outside tire to spin faster than the inside tire to travel the further distance around the corner, making it better on the street. My Mustang turning a corner will break traction and slide around no matter the corner because it has a true posi trac differential. The way you can tell like said above is simple and is a good way to tell but I thought i would shed a little light on what the difference is. There are three types of rear ends (that I know of)... The single track or open end - where one wheel and one wheel only, turns. How lame is that. The common slip or limited slip style diff that puts power to both wheels, but allows for that power to vary from side to side most commonly used in turning. It eliminates one of the tires from chirping or hopping in a turn. Then there is what I call the True Positive Traction Diff. Not to be confused with the "posi-track" used by (GM) or "trac-lok" use by (Ford). This diff does not belong on the street. It is for race cars . It has no side to side slip. The gears are set, no clutches. And if the input turns "x" times both wheels turn "y" times.
Do both tires have to same size 0n the rear with posi trac?
YES, both tires must be the same size on the same axle, be it posi-trac or non posi-trac. Never, ever, mix sizes on any axle.
