Machine cut gears are more precise for less wear and friction. Provides quiet, more efficient operation. Use a light coating of silicon grease. (Note: Part #3195X & 1996X must be used together. A new 2388 main diff gear should also be installed.)
Silicone grease is an amorphous fumed-silica thickened, polysiloxane-based compound, which can be used to provide lubrication and corrosion resistance. Since it is not oil-based, it is often used where oil-based lubricants would attack rubber seals. Silicone greases also maintain stability under high temperatures.
