i have a 2000 dodge 2500 and i was really testing out my new edge comp box and i saw that i was only spinning my right side tire. so i thought i would change the oil in it and add some new ls additive to see if it would help at all. but im not sure what kind of oil to use. thanks all imput is welcome

"9 1/4 - Mopart Synthetic Gear Lubricant 75W-140"
"10 1/2 & 11 1/2 AA - Mopart Synthetic Gear Lubricant 75W-90"

You also need the LSD additive.

make sure you have a lsd... might be an open 80...

You wont fix a worn LSD with new oil. Worn out is worn out.....no matter what oil. The additive prevents clutch chatter, it does not increase "grip" on the clutch pack. I wish you well, but I dont expect your going to find what your looking for in a couple quarts of rear end grease...... You will most likely be looking at replaceing the LSD or upgrade it to a Detroit if you want the two-wheel peel back!

ouch! i was hoping this was going to end better since i have the same problem with my 80. comp box + injectors and that one little tire is roasting like a SOB

Dang, I thought the addative was a friction modifier. I noticed when I put 80-90 in my Nissan posi it seemed to do one leggers worse, and then worked better when I put the right oil back in. Maybe I was mistaken.

Put a detroit locker in!

The dana 80 Trac-loc in the dodges is set up with only about 20% clutch use. All you have to do is take it apart and restack the clutches and it will work better than new.
