Red Line SuperLight ShockProof Gear Oil is a unique product with the viscosity of 75W90 gear oils, but lower internal friction similar to that of an ATF. It contains 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. It is ideal for times when temperatures are not high but the maximum power output is required, such as in stock car qualifying laps. It is useful in two-stroke and four-stroke motocross transmissions, and in 80cc and 125cc shifter kart transmissions. It is also useful in low-power road racing transaxles like Formula Vee and low-power SCCA Production classes (dog-ring type, generally not syncro applications where this product can be slippery).
