Differential Friction Modifier 1 Bottle 3.8oz

The Differential Friction Modifier 1 Bottle 3.8oz (Ford CM-19546-A1) is a specialized lubricant additive designed for Ford differentials that require friction-modifying compounds. This product is essential for mechanics and DIY enthusiasts working on Ford vehicles equipped with limited-slip or locking differential systems, where proper friction characteristics directly impact traction control and differential longevity.

Differential friction modifiers work by reducing the coefficient of friction between clutch plates inside the differential case, allowing for smooth transitions between open and locked states during acceleration and cornering. The formulation is tailored to maintain viscosity stability across temperature extremes while minimizing shear and oxidation, which are critical for high-performance or heavy-duty driving scenarios.

This friction modifier is particularly beneficial for Ford owners with performance builds, towing setups, or vehicles that frequently operate under heavy loads. Its compatibility with OEM differential fluid specifications ensures that it can effectively prevent clutch chatter, noise, and premature wear, making it a valuable addition to any maintenance routine.
