Use the same FilterMag technology that protects your engine and automatic transmission for your differential and manual transmission.
While your manual transmission, differential, or transfer case does the hard work of putting power to the ground, normal wear generates tiny steel particles that circulate in the lubricating oil oil. As the oil continues to circulate, these same particles are carried into every lubricated space. This particle-laden oil will continue to lubricate, but will also contribute to increased wear while it circulates. The longer the oil is used, the greater the wear.
