Red Line 75W90 NS Differential Gear Oil

Red Line 75W90 NS Differential Gear Oil

Quart Bottle  -  RL58304

This GL-5-type gear oil doesn't contain the friction modifiers for limited-slip hypoid differentials. This makes the transmission synchronizers come to equal speeds more quickly, allowing faster shifting and much easier low-temperature shifting. Can also be used in racing limited-slip differentials where weak spring design causes too much wheel spin.

NOTE: this oil is not suitable for the E46 M3 - use Red Line 75W140 gear oil, RL57914

Designed for transmissions and transaxles - helps to slow synchros for easier shifting across a broad temperature range

Popular in Ferrari, Porsche and Subaru transaxles

Muscle car applications like Ford Top Loader, Borg-Warner T-10 and Super T-10, and Muncie transmissions

Contains extreme pressure additives like our 75W90 GL-5 oil, but lacks friction modifiers to balance slipperiness

Improved copper corrosion protection to prolong synchro life

Helps with lock-up on weak limited-slip differentials-compatible with Red Line Limited Slip Friction Modifier for tuning slippage

Also used with clutch-type LSDs in racing for maximum lock up

Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E and SAE J2360

• Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
• Red Line offers lubricants to pinpoint nearly every transmission application
• MTL, MT-85 & MT-90 are not for use in differentials with hypoid gears
• Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates
• Excellent for high- and low-mile transmissions
• Compatible with petroleums and other synthetics
