59ml Silicone Differential Oil 1000.000cst - Arrowmax am-210100  [am-210100]

Precision silicone diff oil for RC setups

This Arrowmax am-210100 silicone diff fluid is designed for scale RC use to adjust how a model's differential transfers torque between wheels. Supplied in a 59ml bottle, it suits hobby electric and nitro vehicles that use silicone oil in planetary or bevel-style differentials.

The 1000.000cst rating defines the fluid's nominal viscosity under standard test conditions. Higher viscosities increase differential coupling under load for improved traction and reduced differential slip, while lower viscosities permit freer action and faster turn-in. Choose this grade when you want a firmer diff response without changing mechanical parts.

Filling most RC diffs is routine maintenance: remove the unit from the chassis if needed, open the case, drain old oil, then refill to the correct internal volume for your diff type. Ensure seals and mating faces are clean and resealed to prevent leaks, avoid overfilling, and cycle the diff slowly to purge trapped air.

Always confirm fit and required oil volume for your specific diff assembly before use. Do not use this product in real vehicle systems.
