Gear Differential Silicone Oil Dot 7 - Yokomo YOKCSDOT7  [YOKCSDOT7]

Silicone oil tuned for gear diffs

This product is an RC-scale silicone oil formulated for gear-type differentials in radio-controlled cars. It is a tuning fluid that alters internal damping and torque transfer inside gear diffs, giving precise control over handling balance without changing mechanical parts.

Application is simple: add or replace the oil inside the gear differential housing to change center, front, or rear differential behavior based on your chassis setup. Small viscosity changes can noticeably affect traction, roll and rotation characteristics; make incremental adjustments and log volumes used.

Installation notes: clean the differential internals and bearings before adding fresh oil to avoid contamination, work on a tidy surface, and cycle the diff after filling so the fluid settles around gears and cross pins. Use proper seals and gaskets to prevent leaks and check for foam or trapped air after filling.

Handling and storage: keep the bottle upright in a cool, dry location, ensure caps are tight, and avoid contact with painted surfaces since silicone oils can affect some paints and plastics. Dispose of leftover fluid according to local chemical waste rules.
