Arrowmax am-210033 Silicone Differential Oil 59ml 300000cst  [am-210033]

Precision silicone diff oil for setup tuning

Arrowmax am-210033 provides 300000cst silicone fluid in a 59ml container for hobby RC differential units. It is offered as an aftermarket tuning fluid for scale on-road and off-road differentials, and should be treated purely as an RC component rather than for any full-size vehicle use.

This oil modifies internal damping: higher viscosity increases resistance between gears or within ball differentials, producing a firmer feel that can improve traction in some cornering scenarios. Choosing lower viscosities reduces internal lock and allows freer wheel speed differentiation.

To install, remove the old fluid, clean and inspect internals, and refill using the differential or chassis maker’s specified fill procedure and quantity. Differential designs vary, so always adhere to manufacturer guidance for your specific unit.

When adjusting setups, change viscosity gradually and test under consistent conditions to assess impact. Note down each viscosity tried and the handling result. Keep the bottle sealed and upright to prevent contamination and loss of volume.
