Description
Heavy-duty gear oils break down under extreme pressure and heat—Lucas Pure Synthetic 75W140 maintains film strength where conventional oils fail, extending differential and transmission bearing life while reducing gear noise. Whether you’re running a limited-slip diff on the street or pushing a competition gearbox to its limits, this synthetic formulation handles sustained high temperatures and shock loads that would compromise standard lubricants.
Engineered for serious applications, Lucas 75W140 delivers the lubricity and thermal stability required in high-performance and commercial powertrains. One gallon covers most differential services and top-off procedures, making it practical to keep on hand.
