  • Smooth oil character that defies the boundaries, even at a high viscosity rating Specifically blended for high-power, FR, and AWD (Rear) applications
  • Reduction in LSD Plate Chattering
  • Ideal for low-volume rear differential cases
  • Exceptionally long fluid life
  • Using the careful, hydro-chemically achieved base mineral oil for unparalleled lubrication, we blend synthetic PAO (Poly-Alpha Olefin), to modify the properties specifically to our LSD. Additional materials such as Boron, and Sulfuric-Phosphors in trace quantities are added to balance the wear, offer superb LSD performance and differential gear lubrication.
  • Because rear differentials have an extreme range of operating temperatures, and very small capacity in the case, Cusco spent an enormous amount of R&D to blend an oil which can withstand abuse. All in all, the Cusco Rear Differential LSD Gear Oil is the right choice for 140 weight oil requirements, which is often ideally suited for motorsports, offering a balance of stable performance, and anti-chattering properties.
