This is the OEM grease used by Traxxas on all its kits. If someone prefers to use the same grease on their traxxas kits as used by the company, then this is the grease to go for. It provides excellent lubrication to the nylon gears etc. by forming a nice film around it. The best part is it's something that can be used almost everywhere. In my opinion, White Lithium Grease is perfect for the inside of a differential. A must buy for anyone looking to rebuild their differential. Not only does it reduce friction, but also reduces the noise of moving parts (Gears etc.). This stuff works like magic!
