Yokomo YOKCSDOT2 - Super Flex Gear Differential Oil Dot 2 (Silicone oil for RC gear differentials)  [YOKCSDOT2]

Super flex differential oil for tuning

The Yokomo YOKCSDOT2 is a silicone-based differential oil formulated for gear-type differentials in R/C models. Designed as a tuning fluid, it changes slip characteristics inside the diff to influence traction transfer and mid-corner behaviour on 1/10 scale on-road and touring setups.

Use it as a drop-in replacement for existing diff fluid: open the differential, drain the old fluid, and apply an appropriate amount of the super flex oil to the gear mesh and internal cavity. Because this product is a softer formulation, expect a smoother, more progressive transfer of power between wheels compared with heavier or thicker diff oils.

Tuning notes: lighter or more flexible oils like this one soften the diff action, which can improve turn-in and traction on low-grip surfaces but may reduce aggressive locking under hard acceleration. Change incrementally and test on-track to find the balance that matches your chassis setup and driving style. Maintain seals and check for leaks after refilling to ensure consistent behaviour.
