Mopar-friction-modifier

To understand why this modifier is necessary, one must understand how a Limited-Slip Differential works. Unlike an open differential, an LSD uses a series of clutch plates to ensure that power is distributed to both wheels, even if one loses traction. However, these clutches are prone to a physical occurrence known as the "stick-slip" phenomenon.

Without the proper lubricant chemistry, the clutch plates can grab and release rapidly during low-speed turns. This manifests as a distracting shudder, mechanical vibration, or "chattering" sound. Over time, this excessive friction doesn't just cause noise; it leads to premature wear of the clutch discs and increased heat within the differential housing.

In the world of automotive maintenance, specifically within the realm of high-performance and heavy-duty drivetrains, the "Mopar Friction Modifier" stands as a critical chemical component. Produced by Stellantis (formerly Chrysler), this additive is engineered to solve a specific mechanical challenge: the inherent "chatter" and uneven engagement found in limited-slip differentials (LSD).
