While many modern synthetic gear oils claim to include friction modifiers "pre-mixed," many Mopar vehicles—particularly Jeep Wranglers, Ram trucks, and Dodge muscle cars—require the specific Mopar additive to meet factory specifications. Using the wrong concentration can be detrimental: too little additive results in continued noise and wear, while too much can make the clutches too slippery, effectively turning a limited-slip differential into an open one and reducing traction.

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. mopar-friction-modifier
