Yokomo YOKCSDOT7 - Super Flex Gear Diff Oil Dot 7  [YOKCSDOT7]

High-flex silicone for gear differentials

This RC-grade silicone oil is formulated specifically for gear-type differentials in radio-controlled cars. It functions as a tuning medium, modifying internal damping and torque transfer to let you dial handling balance without changing mechanical components.

How to use: fill or replace oil inside the gear differential housing to tailor center, front or rear differential behavior according to your chassis and driving style. Because it is a fluid tuner, minor viscosity differences can significantly impact traction and rotational behavior; adjust gradually and note the amounts added.

Installation tips: thoroughly clean diff internals and bearings before adding fresh oil to prevent contamination, work on a clean bench, and rotate the differential after filling so oil settles into gears and cross pins. Fit proper seals to avoid leaks and watch for foam or air bubbles after filling.

Storage and care: store upright in a cool, dry place with the cap secured, avoid contact with painted surfaces as some paints and plastics can be affected, and dispose of surplus fluid in line with local disposal regulations.
