Royal Purple Max Gear Synthetic 75W90 gear oil (5 gallon) is a high-performance gear lubricant designed to protect heavily loaded gears while improving driveline efficiency. Its synthetic formulation reduces gear and bearing wear under severe loads and shock conditions, increases cold-weather fluidity and lubricity, and is noncorrosive to ferrous and nonferrous metals. Max Gear helps gears run smoother and cooler to extend service life.
