75W140NS Gear Oil Synthetic GL-5 Differential Gear Oil 55 Gallon Red Line Oil

Description

These products contain the extreme pressure additives necessary for ultimate protection road cars and racing vehicles, as well as friction modifiers for proper limited-slip operation
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. Ester base stocks and friction modifiers provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
Details:

• Sold as 55 Gallon
• Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils
• Exceed API GL-5 specifications
• Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear
• 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
