Red Line 57104 75W140 Non-Limited Slip Synthetic Gear Oil - 1 Quart

Red Line Gear Oils are designed to provide excellent low temperature characteristics and improved gear protection at higher temperatures. Red Line Gear Oils will reduce differential temperatures 10 to 70 Degree Fahrenheit. Efficiency improvements between 1 to 5 Percent are typical. The synthetic base stocks used have tremendous thermal stability and provide the best film strength available. The unique combination of base stocks and additives allow Red Line gear oils to carry higher loads compared to petroleum lubricants. The stability of these products allow them to be used for extended periods. Red Line 75W90 Gear Oil provides excellent protection in nearly all differentials, conventional and limited slip, in both racing and street use. 75W90NS and 75W140NS can be used in certain limited slip units in racing to lock up the differential. 80W140 should be used in commercial hauling, problem limited slip units, racing applications which see tremendous torque at low speeds, and where noise deadening is desired. Lightweight or SuperLight can be used to obtain maximum power transfer in racing differentials which do not see extremely high temperatures. If "chattering" occurs with any of these lubricants, Red Line Limited Slip Friction Modifier can be used to eliminate the stick/slip action and reduce the noise. This additive should not be necessary in the 75W90, 75W140 or the 80W140 Gear Oils, since they already contain this additive, but in some units more is required. Too much friction modifier can reduce the lockup in limited slip units, so it should only be used if needed.

• CONTAINS - extreme pressure additives like our 75W140 GL-5 oil, but lacks friction modifiers to balance slipperiness, 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
• EXCELLENT FOR - high- and low-mile transmissions, gear protection, synchro protection, and balanced slipperiness for easier shifting in cold climates
• POPULAR GEAR OIL FOR - historic and vintage transmissions, like Mid-1930s to early-1950s synchro-equipped gearboxes in cars and trucks, 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, Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, and SAE J2360
• WHY RED LINE - Established in 1979, Red Line Products perform & protect better than any on the market. No compromises.
