Synslide additive technology truly is beyond synthetic. It is Royal Purple’s advanced Synslide additive technology that gives Royal Purple’s extreme pressure lubricants their amazing performance advantages, therefor making it a superior lubricant. This tenacious, slippery film significantly improves lubrication and reduces wear by increasing the oil film thickness and toughness, which helps to prevent metal-to-metal contact in gears and bearings. Synslide additive technology is Royal Purple’s tough, extreme pressure (EP) lubricating film that provides maximum protection under boundary lubrication conditions typically caused by heavily loaded, slow speed and/or shock load conditions. Max gear is also suitable for use in limited slip/positrac applications. Max Gear outperforms other GL-5 specified gear oils because it combines the highest quality synthetic oils with Royal Purple’s proprietary Synslide additive technology.įor use in differentials, rear axles, manual transmissions and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid. Provides smooth operation and high levels of protection at very high temperatures as well as excellent resistance against shear and ageing. Royal Purple Max Gear makes transmission internals run smoother, quieter, cooler and longer without overhauls. Royal Purple Max Gear 75w90 Fully Synthetic Gearbox Oil is an ultra-tough, high performance automotive transmission gear oil designed to provide maximum protection to heavily loaded gears while maximizing power throughout the drivetrain.
