Ok, Am I the only one with an "Anti-Spin" Diff that thinks they suck donkey or what? I had a few GM's with their G-80 locking diff and they rocked. This thing in the rear end of my Dog is a joke.

If I get on wet grass and the truck is perfectly level, both rears will spin. If I so much as throw a front tire over a curb, I've got a one-wheel-wonder. I can't belive this is how these "Anti-Spin" Diff's are supposed to work. Does anyone out here in cyber world know how they are supposed to be superior to an open diff or what? Cause I would get the same performance out of an open jobby.

Rant Over.

 

I think I read somewhere that light brake pedal pressure is required to, for lack of a better term, "lock up" the rear end.

Winter of '04, we had 10" of snow on the ground. I was able to back mine up the driveway with very little slippage. Course I had about 1000 lbs in the bed.

Good luck with it.

 

Your rear end is of the limited-slip catagory. It is not, nor should it be confused with, a locking differential. Enough tourqe applied and it WILL slip. They are not designed or manufactureed the same. They are intended for empty beds, and normal driving to help reduce spinning over an open carrier. If you intend on anything more than than, then choose the best locking carrier that best fits your usage. Try Detroit http://www.detroitlocker.com/, Powertrax http://www.powertrax.com/ or Eaton http://www.traction.eaton.com/prod6.htmweb.

 

Ain't that the truth. But the AAM TracRite GT can't even put power to a slipping wheel so it isn't much of a limited slip differnential either. I was complaining about being stuck at the beach (BTW, no amount of brake modulation got the wheel with traction moving ) when my buddy laughed saying he got stuck this morning backing out of his driveway.

It's too bad those manufacture's you mentioned don't make anything for the AAM 11.5 axle. I'd be their first customer.

 

Mine has always worked decent. Last week I powerbraked my truck for giggles and left two 20' black marks.

 

copy that... I have a dually and I have pulled off the road with the right side tires pulling a trailer and when leaving the side of the road I stomped on it and the left side hooked without the right side even slipping one bit. I didn't even tare up the grass but left two black marks on the street with the left side. Also I have been in job sites and have never been able to make just one side spin if they spin both spin and I have never even thaught about using the light brake idea either...And my rear end is stock!!!!!!!!!!!!

 

I used to have to back my camper over a curb and when the front wheels hit the curd and I had to pull the front end of my truck over the curb I left 2 8" deep holes where both rear tires spun In my ayrd. I had to put it in 4 wheel drive to finish backing up or I of probably buried it to the rear axle. Maybe it works better in reverse?

 

You're right, I wasn't thinking about that- I apologize. Here is American Axle's site with a few of their diffs, http://www.aam.com/technology/tech_prod_dl_diff.html.

 

The "anti-spin" only works if the main wheel (pass side) has traction. If your main wheel has no grip or traction you might as well have a 1-wheel drive truck. I almost welded my spyder-gears one day when i went to my camp and got stuck in a few inches of sand. I had my diff cover off and my welder ready to go. I was so **** ******!! I cannot wait till a locker is made for these **** new axles. they been out for a few years and no one has made one yet.

 

yeah mine works great on dry pavement and while I have at least some motion on both tires but if you stop and its a little soft or slick count that baby out. The old dana 60 or 80 I had in the 01 was a beast all it needed was a pebble under it for traction to lock them both up. I miss my old truck except for the space and v-10 fuel mileage. It would go anywhere but through hip deep holes with just 285 bridgstone A/T duelers. God dodge pulled a stupid move there

 

"Does anyone out here in cyber world know how they are supposed to be superior to an open diff or what? Cause I would get the same performance out of an open jobby."

The Torsen style limited slip in the Dodges is similar to the limited slips in the H1 and H2 Hummers, but with less bias. A bit of brake may be needed to engage it in some situations. Limited slips are not lockers. Limited slips or lockers should be considered a second line of defense for traction, where proper tires for the situation are the first. You could have super-ultra-mega-lockers front and rear and still do 360s all over the road if the tires aren't adequate.
