Red Line 75W-90 NS GL-5 Gear Oil (No Friction Modifier) - Gallon - 4 Pack

Red Line 75W-90 NS is a fully synthetic GL-5 gear oil with the same extreme-pressure additives as the standard 75W-90 but without friction modifiers, giving crisp synchro engagement in transmissions/transaxles and maximum lock-up in clutch-type limited-slip differentials. It meets GL-5, GL-6, MT-1 and SAE J2360 and is popular in Ferrari, Porsche, and Subaru transaxles and muscle-car gearboxes. Use Red Line Limited-Slip Friction Modifier to tune slippage if needed. Case of four 1-gallon containers.
