75W90 NS GL-5 Gear Oil 

The 75W90NS gear oil contains additional friction modifiers for suitability with clutch-type limited slip differentials - for most LSDs, no additional friction modifiers are required. This is the recommended fluid for rear differentials which use clutch packs or have an LSD.

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

Popular in Ferrari, Porsche and Subaru transaxles

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

This gear oil is recommended for the daily driver while the MT90 is more designed for race applications. Unlike the MT90, the 75W90ns will not give you the notchy feeling when cold.
