Gear Oil

Gear lubricant for differentials, transfer cases and manual gearboxes, in 75W-90, 75W-140 and 80W-90.

Note the LS designation where it appears: limited-slip differentials need the friction modifier, and a straight gear lube in an LS diff will chatter. We list it in the title so it cannot be missed, in single quarts and in cases of two, six and twelve.
