The term Anti-Spin Rear axle that Dodge uses, is this just an open diff?
If one rear wheel is say on Ice and the other on dry ground will the wheel on the ice just spin and the wheel on dry ground not turn?

 

It is a torque sensing limited slip. It uses gears to limit wheel to wheel slip versis clutch packs. It is better than a limited slip. AAM also has a GTL witch is the same limit slip we have now, but it can lock like a locker (wonder if it would fit in the 11.5 rear end)

However if you take a truck with anything in it, open, locker, spool, and put one on ice, and put one on dry ground and floor it, I garentee you will hear POW and not move anywhere

If you put one on ice, and one on the road and gas it, yes the one on ice will spin because of the torque difference. Limit slips are designed to help equil torque (like one wheel on wet pavement, vrs dry pavement) but when one is on ice and you haev 500lbs of torque going to it, it's gonna spin one wheel. However if you ease into the gas, you will take off faster than if a truck with an open rear was in the same situation. That truck will only spin the wheel on ice and will move very slow, with the limited slip you will move much faster if your controling on the gas.

Now if you use your brakes a bit (they teach this when driving hummers) you can get the differental torque difference closer, and take off even faster (even though you have some brake on) e-brake is a good use for this as it's easy and you can just let it go.

It's not as good as a locker, but for the street, towing, ect there much nicer than full lockers (easyier on gears, axles, tires, ect) If you towed a 5th weel or anything very heavy that dosn'et let a tire slip when turning (like a race car spool) you will snap something

 

The TracRite GT is a limited slip differential. You either love it or hate it.

Like most gear-type units its great on dry pavement but loses it effectiveness when you are stopped and one wheel has poor traction. Slightly applying the brakes usually will get the tire with traction spinning but this trick can work with an open differential also.

 

So I'm a bit slow this morning, so our rear axle is like the second one in the following link "Positraction & Limited slips"?

No, read further down on that list. The TracRite GT is closer in design to the Detroit TrueTrac.

The bias of the TracRite is not as aggressive as the TrueTrac

 

Ok, so if my truck has the "Anti-Spin Differential Rear Axle" (code DSA) you are saying it is the TracRite?

 

Yes, look here:

"No, read further down on that list. The TracRite GT is closer in design to the Detroit TrueTrac. "



It says... Detroit Truetrac (TT)
Based on the worm gear principal and works like clutch type positraction. Does not wear out, not recommended for tall tires over 33".

How is the AAM diiferent in that respect?

Sorry. I read further...
Detroit Truetracs are similar in design to the Gleason Torsen®, only the Truetracs hold up well with reasonably tall tires. They use worm wheel gears that work on the same principle as a worm gear.

 

Why does everyone reference the "anti-spin" as stated on my window sticker, as a "limited-slip". The way I understood it, those were two different terms. I had a 2000 Dodge Ram 2500 with the anti-spin rear end 4.10 gears. When I had the rear end off the ground, with the truck in park, spinning one tire forward would make the other tire spin forward. I now own a 2005 Dodge Ram 2500 with the "anti-spin" rear differential 4.10 gears. Just to check things because I didn't think it was working, I performed the same test. One tire was spun forward and the other went backward. The first example is for sure an "anti-spin" I look at the second example as a "limited-slip". I took my truck in to check it out, and didn't notice it until today, they marked up the service sheet saying "check out the 'limited-slip' rear diff.". Are these two terms supposed to be interchangeable, and why the difference in how they work?
