75 ml bottle of silicone oil for 5.000cst differentials from Ultimate Racing. The differential oil from Ultimate Racing is made with 100% pure silicone to provide stable performance at any working temperature, delaying differential fatigue. The silicone grading is in Cst, and the higher the article number, the greater the density. It also contains anti-friction additives that minimize friction and thus reduce wear on the differential gears.
