Built To Protect Your Drivetrain In Every Condition

Royal Purple 75W-90 Synthetic Gear Oil is formulated with a proprietary additive blend that gives it exceptional load-carrying capability and corrosion resistance. It meets or exceeds API GL-5 specifications, making it ideal for a wide range of applications including open, limited-slip, and locking differentials. One of its standout characteristics is its ability to separate quickly from water, which is critical in harsh environments where moisture intrusion can lead to accelerated wear. The synthetic base stock improves cold-weather flow while maintaining stability under high temperatures, ensuring consistent protection across a wide range of operating conditions. Its low coefficient of friction means less internal drag, which can translate into improved fuel economy and more power to the wheels. The integrated friction modifier makes it compatible with most limited-slip setups straight out of the bottle. Whether you're dealing with sudden shock loads or crawling at low RPMs, this gear oil is designed to keep components clean, quiet, and running longer.
