The Red Line 75W90NS GL-5 Gear Oil is specifically formulated for use in transmissions, transaxles, and limited-slip differentials, providing optimal performance across a wide temperature range. Its advanced formulation helps prevent lock-up issues on weak limited-slip differentials when used with Red Line Limited Slip Friction Modifier, making it suitable for enhanced traction control in high-performance applications. This gear oil contains extreme pressure additives, including 75W90 GL-5 oil, designed to withstand heavy loads and reduce wear, while lacking friction modifiers to maintain balanced slipperiness in various racing and street conditions. Its non-corrosive formula is safe for all synchro materials, ensuring longevity and smooth gear engagement. The oil is popular among muscle car enthusiasts, especially for Ford Top Loader, Muncie transmissions, Borg-Warner T-10, and Super T-10 models, and is recommended for use in API GL-5, GL-6, MT-1, MIL-L-2105E, and SAE J2360 specifications. Additionally, the gear oil is used with clutch-type limited-slip differentials in racing environments to achieve maximum lock-up performance. Improved copper corrosion protection enhances synchro life, reducing maintenance needs and extending transmission service intervals. Widely trusted in high-performance vehicles such as Ferrari, Porsche, and Subaru transaxles, this gear oil delivers reliable protection and efficient shifting for demanding driving conditions.
