Red Line LightWeight ShockProof is a unique synthetic gear oil that suspends solid microscopic particles to build a film greater than an SAE 75W-140 while keeping fluid friction as low as an 80W gear oil or 30W motor oil. It suits moderate-power transmissions and differentials that see higher loads, heat, and shock than the SuperLight grade can handle. Case of four 1-gallon containers.
