MOTORCRAFT FRICTION MODIFIER

This friction modifier is a specially formulated additive to provide smooth operation of clutch-type limited-slip differentials. 1 bottle of friction modifier is required when changing the gear oil in rear ends equipped with Ford traction-lock units.

ROYAL PURPLE MAX-GEAR OIL

Royal Purple Max-Gear gear oil is an ultra-tough automotive gear oil. It is designed to maximize power and provide unsurpassed protection to heavily loaded gears. It makes gears run smoother, quieter, cooler, and longer without overhauls. Max-Gear outperforms other gear oils because it combines the highest quality synthetic oils with Royal Purple’s proprietary Synslide additive technology.
