Red Line 75W140NS Gear Oil is designed to provide the highest degree of protection and greatest efficiency for your drivetrain. Red Line's drivetrain lubricants are optimized for differential, transmission, or transaxle use over a wide range of temperatures. Red Line Gear Oils contain polyol-ester base-stocks to provide excellent lubrication even under the extreme conditions of high-loading and high- temperatures--their natural lubricity provide excellent slipperiness which reduces the sliding friction in hypoid gears to reduce wear and temperatures. The synthetic base-stocks have a natural multi-grade property, so large amounts of unstable thickeners are not required, which means that Red Line Gear Oils will provide a stable viscosity for even extended periods of use.
Red Line's 75W140NS is 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.
- Fully-synthetic polyol ester base stocks -excellent lubrication under extreme conditions
- High viscosity-index (VI) for consistent viscosity and film thickness with varying temperatures
- Ester base stocks and friction modifiers provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
- Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils
- Exceeds API GL-5 specifications
