looking at two trucks almost identical at two different dealers

the only difference is one has the anti-spin the other dont and the color

its only 285 dollars difference but that is not the issue

the difference will be who offers the most on trade in

so my question is do i need the anti-spin on a 4wheel drive or not

what will be the difference if i get one with or the one without

i do no offroading or no mudslinging

 

Then why buy 4x4?

most here agree the "anti-spin" differential doesn't work any better than a steaming pile of dog . It works as long as both tires can spin equally, if one tire is airborne or can get good traction, then the anti spin differential doesn't work.

 

I had one wheel peel and changed out to anti-spin. These trucks are so heavy up front that they have bad traction even with posi. I would burn my right rear all the time!
Now I burn both tires!

 

I am totally opposite in opinion, yeah there are sometimes at low speeds where there is not enough momentum and torque for the anti-spin to work, but it is by far, better than a limited slip. Look at the Ford boys when they do burnouts, turn the steering wheel right or left and one tire spins. The Dodge will burn both off no matter the situation.

 

Having had several vehicles with locking differentials I like the anti-spin option and looked all over northern Ca before finding my vehicle.

The anti spin may not be perfect but it is definitely more streetable than a locker while still providing a posi.

Apparently there is no aftermarket Mfg currently making lockers for these new differentials yet. Even if there was I'd only purchase a front locker and not have to deal with the constant popping and banging normally associated with gear driven locking differentials on the street. I would not consider a clutch type unit on a vehicle this heavy.

When I purchased my truck the anti-spin diff was only a $50.00 option. One which I thought was well worth the price!

With a Torsen type limited slip you might have to use some brake to get it to engage, just like on military HumVees. A limited slip works well on mixed traction surfaces. I am waiting for a selectable locker, which isn't available yet, as I prefer an open diff on ice and other uniformly slick surfaces. An open diff will 'fail gracefully', a tire will slip and then you can engage the 4x4, while a limited slip can kick the rear end around, which isn't 'graceful' if you go off the road, or hit a sign, or slam into another vehicle, etc.

I appear to be a small minority of opinion though.

 

Looks like Im mistaken on what I thought the general opinion on the anti spin differential was here....

 

The anti spin works fine if you know how to use it. If one tire starts to spin, and you tap the brakes, it will "lock" the anti spin and both tires will spin.. I wouldnt own a 4x4 truck without it, and I dont do any off roading.

I specifically ordered my truck without the limited slip. they are dangerous and useless in wet, icy, or snowy conditions in my expirience. besides, if you have 4-wheel drive then use it. i am waiting for a selectable locker.

 

I agree, I do limited off-roading tho. The anti-spin in the dodge is very predictable and I have had no problems with it. My corvette has a clutch type limit slip and when it decides to lock it does so instantly which usually results in fishtailing. I like the one in the Dodge better. A selectable diff would be better, but they are not available yet.

I agree with you 100%. I used mine yesterday to get myself out of a situation that had I gotten into while trying to back my trailor down my road. I had my passenger side front & rear wheels off the road stuck to the wheel caps in the mud (in a really soft drainage ditch) with my trailor at almost 90 degrees (don't ask, it's a long story). Played with it for long enough rocking it backwards and forwards to get enough area clear so that I could take a solid stab at it with the anti spin activated. Once I got the momentum going I hit the P-brake, she smoked up something crazy with both tires ah howling (one on the pavement and the other in the mud/soft wet grass). Got her moving and she pulled right through trailor and all. Felt like a complete bone head as the wife was not to my knowlege sitting there waiting to pass by to get to our street. All she could say was " I told you to get the 4x4.

 

my limited slip rear works fine for what i need... if i start getting on the throttle a little harder in a corner, it will start to lockup a bit, and if i get into the throttle real well, it will lockup. it'll leave 2 black marks on pavement... interesting to see a differential with no traditional spider gears in it...

 

reading all of the post above, IMO for $285, its better to have it and not need it, then to need it and not have it...

Its All Good

 

Any kind of wet grass etc.you'll regret not have anti/spin.

 

If you know how to use the anti spin...it works wonderfully.
