Kendall^® Special Limited-Slip Gear Lubricant is an extreme-pressure, API GL-5, SAE 80W-90 automotive gear oil specially formulated to satisfy the lubrication needs of most limited-slip rear axles. It is friction-modified to help eliminate the stick-slip chatter associated with low-speed, high-torque operation of limited-slip differentials while turning corners with some passenger cars and light trucks.
