Oil CompositionFull Synthetic

Royal Purple® Max Gear® is recommended for use in automotive front and rear differentials, manual transmissions and transfer cases that specify use of an API GL-5 or GL-4 fluid. It is noncorrosive to soft yellow metals (brass, bronze, copper), and is synchronizer safe. Max Gear also works great in marine gear applications. Not for use in gear boxes, transmissions, and lower units with wet clutches. Max Gear is an ultra-tough, high performance gear oil designed to provide maximum protection to heavily loaded gears while maximizing power throughout the drivetrain. Max Gear outperforms ordinary gear oils by combining the highest quality synthetic oils with Royal Purple’s proprietary Synerlec® additive technology. Max Gear makes gears run smoother, quieter, cooler and longer without overhauls.

    Did not need to add friction modifier as it comes with some premixed. Used in my Ford 8.8 Rear End. I thought my clutch packs were bad but I just added too much friction modifier with another Gear Oil brand I previously used.
