Premium Synthetic High Temp Gear Grease.
This was the cure we created for the K brand truggy gear issue some 10 years ago.
The hypoid angle of the gear teeth would create a ton of heat and subsequently soften the plastic gear case where the pinion bearings resided causing the mesh to open and ultimately strip the ring gear teeth. A proper amount of our gear grease removed the heat and thus solved the issue.
* Great for all metal-metal gear contact
*Can also be used on plastic gears with sealed fluid type differentials
(Not recommended for ball type differentials due to silicone ball diff grease and synthetic/petroleum base greases do not mix, they turn to paste) |
