Max-Gear® is an ultra-tough, high performance, GL-5 automotive gear oil designed to provide maximum protection to heavily loaded gears while maximizing power output throughout the drive train. It outperforms other GL-5 gear oils because it combines the highest quality synthetic oils with Royal Purple's proprietary Synslide® additive technology.

Max-Gear® makes gears run smoother, quieter, cooler and longer without overhauls.

Note: All viscosities of Max-Gear® are formulated with hypoid friction modifiers necessary for use in clutch or cone type differentials. No additional additives are necessary.

New from Royal Purple...Synchromax® Manual Transmission Fluid is recommended for manual transmissions that specify an automatic transmission fluid or motor oil (ie: Tremic TKO) that require either an automatic transmission fluid, multi-viscosity motor oil or straight grade motor oil. It is also ideal for 2-cycle motorcycle gear boxes.

Feel the difference. It is also ideal for 4x4 transfer cases and/or 2-cycle motorcycle gear boxes. Synchromax is formulated with Royal Purple's synthetic, proprietary Synerlec additive technology, which offers improved shift quality over a wide temperature range and reduced gear noise. It is fully compatible with all types of friction materials, and offers excellent corrosion and oxidation protection.
