AMSOIL Severe Gear is compatible with most limited-slip differentials. If limited-slip differential chatter occurs, add AMSOIL Slip-Lock™ friction modifier additive.
I bought a 4oz tube of the Slip-Lock just in case...But I didn't need it... With the (EP) Gear Lube 75W-140 (SVO)
in my Ford 10.50 rear end...
I think it all depends on the condition of your limited slip clutches...
