Differental Oil Additive / Friction Modifier 4oz.

The Differential Oil Additive / Friction Modifier 4oz from DANA-SPICER is designed to enhance the performance of differential assemblies in both modern and classic vehicles. This friction modifier is particularly useful for builders and mechanics working with limited-slip and locking differentials, especially when using synthetic oils or upgrading drivetrain components.

This additive helps ensure proper clutch pack engagement and reduces noise during operation, which can improve handling and acceleration. It is formulated to maintain the necessary friction coefficients for smooth operation under load transitions, addressing the common issue of slippage and noise that can occur with aging oils.

Ideal for maintenance intervals, rebuilds, or when switching to synthetic gear oil, this additive is compatible with a range of truck and automotive differentials, including Dana 60, 70, 80, and 9.75-inch assemblies. It works best with synthetic 75W-90 or 80W-140 oils, making it a valuable addition for performance upgrades.
