Arrowmax AM-210058 59ml Silicone Differential Fluid 9.000cSt Precision  [AM-210058]

Silicone differential oil for setup and balance

The Arrowmax AM-210058 bottle contains 59ml of silicone differential oil with a 9.000cSt viscosity, intended for hobby RC car differentials. It adjusts how torque is shared between wheels and is useful when tuning cornering responses.

Viscosity selection changes diff coupling and transient behaviour: lower viscosities permit freer differential action, while higher grades increase coupling and traction. This 9.000cSt option is useful for incremental tuning without excess waste.

Fitting advice: clean diff internals before refilling, add oil carefully to avoid overfilling, and reassemble to maintain seal performance. Store the bottle sealed at stable room temperature and out of direct sunlight.
