Red Line 58404 Lightweight ShockProof Gear Oil - 1 Quart, (Pack of 12)
Red Line's Lightweight ShockProof Gear Oil is 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 and may be used to obtain maximum power transfer in racing differentials which do not see high temperatures. It is similar to a 75W140 gear oil, but with the lower internal friction of an SAE 30 motor oil.  ShockProof Gear Oils are unique lubricants containing a suspension of solid microscopic particles as an extreme pressure agent--unique solid dispersion which cushions gear teeth to help prevent tooth breakage and allows the use of lower viscosities. The viscosity characteristics allow the lubricant to resist throwoff and provide a film thickness greater than an SAE 250 grade, with the same low fluid friction as with our 80W140. It is recommended for heavily-loaded racing differentials and transmissions, Off Road racing and problem gearboxes and offers a "best of both worlds" balance of relatively low drag and the utmost in protection.
