Brand: Red Line Synthetic Oil
Red Line Non-Slip Synthetic Gear Oil is very similar to standard Red Line Synthetic Gear Oil, but with a special formulation to help ensure more effective lock-up of clutch-type limited slip differentials. This can be used to revive worn clutch packs, or even to speed shifting in transmissions with worn synchros. Exceeds GL-5 protection ratings* and satisfies GL-5, GL-6, MIL-L-2105E, and SAE J2360 specifications.
* Note that conventional oils providing GL-5 protection for hypoid differentials can be corrosive to synchros. Red Line synthetic gear oils are non-corrosive to 300° F and are suitable for use in manual transmissions.
75W140NS - Ideal for heavily-loaded racing clutch-type limited slip differentials (LSD). Also popular for vintage manual transmissions (mid-1930s to early 50s), and shown to reduce noise and rough shifting in late-60s Mopar A-833 4-speed transmissions. Can be mixed with 75W90NS to customize a lower viscosity.
75W90NS - For racing LSDs, manual transmissions, and transaxles. Popular in Ferrari, Porsche, and Subaru transaxles. Recommended for Ford Toploader, T-10, Super T-10, and Muncie transmissions.
Note: Due to its lock-up characteristics, Non-Slip oil may cause increased noise and chatter in street-driven limited-slip differentials. The lock-up can be tuned by adding a small amount of Red Line Friction Modifier (Part No. 1687-4oz) or by mixing with standard Red Line Synthetic Gear Oil (Part No. 1693).
