Silicone Diff Fluid 300000cst 59ml for RC - Arrowmax am-210033  [am-210033]

Silicone differential fluid for scale RCs

Arrowmax am-210033 is supplied as a 59ml silicone differential fluid rated at 300000cst for hobby RC differential units. It serves as an aftermarket tuning fluid for those adjusting diff damping on scale on-road and off-road models, and is not intended for real-vehicle applications.

The fluid adjusts internal damping levels: increasing viscosity raises internal resistance and can give a more locked diff effect under load, affecting cornering and traction on surfaces such as carpet and hardpack. Lower viscosities reduce internal drag and allow freer differential action.

Fitting the fluid follows standard diff service practice: drain the existing oil, clean the internals and refill per the differential or chassis instructions for correct volume and method. Different diff architectures require following the specific maker’s guidance.

For setup work, alter viscosity in measured steps and record handling observations with each change. Store the bottle capped and upright to keep the fluid clean and prevent evaporation.
