Synthetic 75w140 Trans/ Diff Lube 4x1 Gal

Synthetic 75w140 Trans/Diff Lube 4x1 Gal by Lucas Oil is a premium synthetic gear oil formulated for heavy-duty transmission and differential protection in demanding automotive applications. This four-gallon set delivers professional-grade lubrication engineered for vehicles that experience extreme pressure, high torque loads, and severe operating conditions. Whether you're maintaining a high-performance truck, towing vehicle, or specialized equipment, this synthetic formulation provides the thermal stability and anti-wear protection required for extended service intervals and long component life.

The 75W140 viscosity rating ensures optimal flow at cold start temperatures while maintaining a robust protective film under extreme heat and load. This synthetic blend features built-in limited-slip additives that enhance friction control in limited-slip differentials, reducing chatter and improving traction without compromising smooth engagement. The synthetic base stock resists oxidation and thermal breakdown far longer than conventional mineral oils, reducing sludge formation and extending drain intervals—a significant advantage for fleet operators and serious enthusiasts who demand reliability and cost efficiency.

Ideal for pickup trucks, SUVs, performance vehicles, and industrial equipment using limited-slip differentials or synchronizer-equipped transmissions, Synthetic 75w140 Trans/Diff Lube performs reliably in both street and severe-duty off-road environments. The four 1-gallon jug format provides convenience for multiple-vehicle fleets, service facilities, or those preferring bulk supplies. Lucas Oil's proven reputation for protection under extreme conditions makes this gear oil a trusted choice for drivers who refuse to compromise on drivetrain longevity and performance, especially in towing, racing, or high-altitude applications where standard oils fall short.
