Red Line NS GL-5 Gear Oil - 75W90 - 1 Quart - 58305 Item # 2170950

Description
Since most GL-5 gear oils for differentials are too slippery for manual transmissions, these products ensure proper shifting while providing maximum wear protection.
Features:
- Provides an appropriate coefficient of friction for most manual transmission synchronizers (other synthetic gear oils are often too slippery for proper synchro engagement)
- Lubricants are available to cover nearly every transmission application
- Delivers excellent gear and synchro protection with balanced slipperiness for easier shifting in cold climates
- Suitable for both high- and low-mileage transmissions
- Compatible with petroleum-based and synthetic oils
- Designed for transmissions and transaxles to slow synchros for easier shifting across a broad temperature range
- Popular in Ferrari, Porsche, and Subaru transaxles
- Suitable for muscle car applications, including Ford Top Loader, Muncie transmissions, Borg-Warner T-10, and Super T-10
- Contains extreme pressure additives similar to 75W-90 GL-5 oil, without friction modifiers to balance slipperiness
- Improved copper corrosion protection to extend synchro life
- Compatible with limited-slip friction modifiers to tune slippage and assist lock-up on weak limited-slip differentials
- Also suitable for clutch-type LSDs in racing for maximum lock-up
- Meets API GL-5, GL-6, MT-1, MIL-L-2105E, and SAE J2360 specifications
- Non-corrosive formula, safe for all synchro materials
Note: MT-LV, MTL, MT-85, and MT-90 are not for use in differentials with hypoid gears.
