A full synthetic 75W140 gear oil made from polyol ester base stocks, with the extreme-pressure additives of Red Line's 75W140 GL-5 but no friction modifiers (NS). Red Line says it exceeds API GL-5 and suggests it for historic and vintage synchro gearboxes, noisy 1964-1969 Dodge/Plymouth A-833 four-speeds, and clutch-type limited-slip differentials in racing where maximum lock-up is wanted. It is non-corrosive and safe with all synchro materials.

✓Contains extreme pressure additives like our 75W140 GL-5 oil, but lacks friction modifiers to balance slipperiness
✓Popular for historic and vintage transmissions, like Mid-1930s to early-1950s synchro-equipped gearboxes in cars and trucks
✓Helps with noisy or rough shifting in troubled A-833 Dodge/Plymouth 4-speed transmissions from 1964 to 1969
✓Option for noisy transmissions when mixed with 75W90NS or MT-90 to bring viscosity level up
✓Also used in clutch-type limited slip differentials in racing for maximum lock up-some users add Limited Slip Friction Modifier in small doses to customize slippage
✓Non corrosive formula, safe for use with all synchro materials
✓Fully-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions
✓High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change
✓Exceed API GL-5 specifications
