Royal Purple's Max-Gear® synthetic severe-service oil is specifically formulated to handle the strain. Max-Gear® provides maximum protection to heavily loaded gears while maximizing power output throughout the drive train. Its shock load protection reduces fatigue failure in gears and bearings. Max Gear's film strength is up to 300 percent greater than other gear oils. Max-Gear's low coefficient of friction saves energy, reduces temperatures and requires no OEM or aftermarket limited-slip additive.
