Synthetic 75w140 Trans/ Diff Lube 4x1 Gal

Lucas Oil Synthetic 75w140 Trans/Diff Lube 4x1 Gal is specifically designed for high-stress drivetrain applications where extreme pressure protection and thermal stability are essential. This product is ideal for modified trucks with aftermarket gearing, performance cars with limited-slip differentials, and daily drivers that frequently tow heavy loads.

The synthetic formulation offers superior film strength to prevent gear wear and extend the life of components. With a viscosity grade of 75w140, it maintains optimal performance across varying temperatures, ensuring a protective oil film during peak load events while flowing freely during cold starts. The formulation includes anti-wear additives (ZDDP) that adhere to gear and bearing surfaces, reducing the risk of micro-welding and spalling.

Mechanics and automotive enthusiasts trust Lucas Oil Synthetic 75w140 Trans/Diff Lube for vehicles with performance modifications, as it is the same chemistry used in competition vehicles and heavy-duty commercial fleets. The 4-gallon bulk pack ensures you have enough supply for transmission top-ups, differential servicing, and transfer case maintenance across multiple vehicles or seasonal maintenance cycles.
