Any guesses on why I got this??

And no, my axle and differential now are perfectly fine...

Because drag race?

Changing out your rear gear?

Yup

Going from 3.55's to 3.92's! Got the axle out of a 1998 Dodge Ram SS/T. We're just going to swap axles, hoping to have it done in about a week or so!

Sweet. I have 3.92s they are nice. LSD?

**ramthis9501** · 09-01-2012, 03:33 PM

Yup! It's actually more of a posi-trac because the build sheet on the truck said "Anti-Spin Rear Differential"

Same deal I have on mine...the 3.92 with the Anti-Spin

**ramthis9501** · 09-01-2012, 04:56 PM

So with Anti-Spin, do both of your tires spin instead of just one like it does with open diff?

From what I have read. both will spin if both have equal traction, it's not a locker where the traction is unbiased, it will still give more torque to the higher friction wheel.

I don't drive my truck hard or try to spin the wheels, though. (freakin 20's are too damn expensive), as a matter of fact, the only time I have even had this thing over 3K RPM was racing Lee on the way to a show. With that being said, the only experience I can offer is from what I have read on it as I don't have any real experience to prove or disprove how good the factory LSD is.

If its the same rear gear I have, they both spin. It's a little interesting in the rain lol.
