Limited Slip Diff Frict Modifier Case/12-4oz

The Limited Slip Differential Friction Modifier Case of 12 (4 oz bottles) by Redline Oil is designed for drivers and mechanics who require precision control in vehicles with limited-slip differentials. This friction modifier additive addresses a common issue: factory differential fluids often lack the necessary chemical compounds to optimize clutch pack engagement and prevent chatter during cornering.

Redline's friction modifier works by increasing the coefficient of friction between the clutch plates inside the limited-slip differential, promoting smooth power transfer and eliminating noise or shudder caused by uneven torque distribution. It is fully miscible with both conventional and synthetic differential oils, requiring proper dilution ratios, typically 4–6 ounces per quart of fluid, depending on the manufacturer's specifications.

This case is ideal for maintaining street performance vehicles, weekend track cars, or managing a fleet of trucks, ensuring that professionals and enthusiasts have the product readily available. Redline's formula has been refined through decades of motorsports and OEM validation, providing consistent viscosity stability and anti-wear protection across temperature extremes.
