Amsoil Slip Lock

[N CHARG]

Has anyone used the Amsoil Slip Lock in the differential verse the Mopar additive? About to change both my Vipers and wondering if this works as well or better?

I don't believe you'll need the friction modifier.

I drained and fill the diffs in both my 94 and 2000 with AMSOIL SEVERE GEAR 75W-140 100% Synthetic Gear Lube. This lube has friction modifiers included. They both are driving great.
