Red Line Lightweight ShockProof Gear Oil Achieve exceptional low-temperature flow and enhanced cold shifting this gear oil. Ideal for racing differentials under moderate loads, it ensures optimal performance in demanding conditions. Features: Film thickness greater than an SAE 75W140, yet low fluid friction like 80W gear oil or 30W motor oil Unique lubricant with solid microscopic particles offers low drag/high protection 40 lower coefficient of friction and 250 of the load carrying capacity of conventional gear oils Relatively low viscosity, yet cushions gear teeth under extreme pressure Helps to prevent tooth breakage, resists throw-off
