Royal Purple 06301 75w140 Max Gear Oil Case, 6 Quart, 1 Pack

Max gear is recommended for use in truck and automotive front or rear differentials, manual transmissions and lower gear units of marine engines that specify use of an api GL-5 or GL-4 fluid. It is non-corrosive to soft yellow metals (brass, bronze, copper, etc.) and synchronizer safe. Specially designed to extend gear and bearing life, max gear provides superior corrosion protection over competing conventional and synthetic gear oils.
