Red Line Light Weight ShockProof

Price: $18.95

A unique gear oil designed to lubricate racing transmissions and
transaxles which see serious loads (not recommended for most
syncro-type transmissions). It has excellent low-temperature flow which
allows easier shifting when cold. May be used to obtain maximum power
transfer in racing differentials which do not see high temperatures.
Similar to a 75W140 gear oil, but with the lower internal friction of
an SAE 30 motor oil. Used in most road-racing differentials with moderate power and dogring racing transaxles.
