RedLine: 75W140NS GL-5 Gear Oil - quart
- 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
Product Details:
- Fully-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions
- Ester base stocks and friction modifiers (except NS) provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
- High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change
- 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
