Silicone Differential Oil for RC Differentials - Arrowmax am-210100 1000.000cst  [am-210100]

Compatibility and recommended uses

This Arrowmax am-210100 silicone diff fluid is formulated for scale RC differentials to influence how torque is split between wheels. The 59ml bottle is intended for use in hobby electric and nitro cars that rely on silicone oil inside planetary or bevel-style diffs.

The 1000.000cst value denotes the fluid's nominal viscosity at test conditions. Higher viscosities increase internal coupling under load for steadier traction and reduced slip, while lower viscosities permit freer differential behaviour and quicker cornering responses. This oil is ideal when a firmer diff characteristic is required without mechanical changes.

Routine servicing generally involves removing the differential if necessary, opening the case, draining the previous oil, and refilling to the specified internal volume. Clean sealing faces, reseal the housing properly to prevent leaks, and operate the diff slowly after filling to allow trapped air to escape.

Always verify that this fluid and the supplied volume suit your specific diff assembly. Do not use this fluid in real vehicle systems.
