Its friction-modifier-free formula helps maintain strong gear engagement and maximum lockup in clutch-type limited-slip differentials, making it a practical choice for racing applications where controlled slippage is important.\u003c\/p\u003e\n\n\u003cp\u003eThis Red Line gear oil is also well suited for historic and vintage manual transmissions, including synchro-equipped gearboxes used in cars and trucks from the mid-1930s through the early 1950s. It can help address noisy or rough shifting in select A-833 Dodge and Plymouth 4-speed transmissions from 1964 through 1969. When additional viscosity is needed, it may also be blended with Red Line 75W90NS or MT-90 to help tune transmission performance. The non-corrosive formulation is compatible with common synchronizer materials.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Manual transmissions, racing gearboxes, and clutch-type limited-slip differentials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eViscosity:\u003c\/strong\u003e SAE 75W-140\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGear Oil Type:\u003c\/strong\u003e Non-slip, friction-modifier-free formulation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePerformance Level:\u003c\/strong\u003e Contains extreme-pressure additives comparable to GL-5 gear oil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSynchronizer Compatibility:\u003c\/strong\u003e Safe for use with all synchro materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLimited-Slip Use:\u003c\/strong\u003e Supports maximum lockup; friction modifier may be added in small amounts to adjust slippage\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlend Compatibility:\u003c\/strong\u003e Can be mixed with 75W90NS or MT-90 when appropriate to increase viscosity\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e Quart container\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e One quart of Red Line 75W140NS Gear Oil, Part Number RED57104.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e Suitable for select vintage and historic manual transmissions, racing applications, clutch-type limited-slip differentials, and A-833 Dodge and Plymouth 4-speed transmissions from 1964 through 1969.
