if u use amsoil u won't likley need modifier

if u have some limited slip chatter around corners then u need the Amsoil LS additive

make sure u use the proper weight front and rear no matter what brand u use

forward is an open diff it needs no additive

Go with AMSOIL Sever Gear. Great Stuff! I run 75-140 in front and rear. I would burn up Motorcraft gear oil way happier since I switched to Severe Gear.

And ZMANN is spot on [QUOTE=ZMANN;9439153]if u use amsoil u won't likley need modifier

if u have some limited slip chatter around corners then u need the Amsoil LS additive
