Description

The Red Line 75W140NS GL-5 Gear Oil is a synthetic lubricant designed for specific transmission and differential applications. It contains extreme pressure additives but lacks friction modifiers to balance slipperiness. This gear oil is popular for vintage transmissions and can help with noisy or rough shifting in certain Dodge/Plymouth 4-speed transmissions. It is also used in racing clutch-type limited slip differentials for maximum lock-up and is non-corrosive, making it safe for all synchro materials.
