Nulon SAE 85W-140 Limited Slip Differential Oil (LSD85W140) is developed for limited slip differential applications to withstand high loads and repeated shock-load conditions. Also ideal for conventional differentials and vehicles that operate under heavy duty conditions such as 4x4, towing, or carrying heavy loads. Nulon LSD85W140 is suitable for use where API GL-5 or GL-6 (obsolete) is recommended. Nulon Limited Slip Differential oil is formulated using the synergy of high viscosity base fluids with an extreme pressure additive system, corrosion inhibitor and friction modifier technology to enhance wear protection, corrosion resistance, and smooth operation in limited slip differentials. Nulon Limited Slip Differential oils engineered using high shear stable material to withstand extreme load and maintain viscosity.
