RED LINE GEAR & TRANSMISSION LUBRICANTS are designed to provide excellent low-temperature shift ability and improved gear protection at high temperatures. Red Line Gear Oils will reduce differential temperatures 10-70ºF. Efficiency improvements between 1-5% are typical. The synthetic base stocks used have tremendous thermal stability and provide the best film strength available. The unique combination of base stocks and additives allow Red Line gear and transmission oils to carry higher loads compared to petroleum lubricants. The stability of Redline base stocks have a natural multigrade property, so large amounts of unstable thickeners are not required to manufacture Redline gear oils, this means that Redline gear oils will provide a stable viscosity for even extended periods of use. Redline also manufactures gear oils that can be used in limited slip differentials with the use of additional friction modifiers.
