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

Silicone diff fluid for on- and off-road RC tuning

Arrowmax AM-210058 supplies 59ml of 9.000cSt silicone differential fluid designed for RC car diffs. The fluid alters torque transfer between wheels and is a straightforward tool for adjusting how a model behaves through corners.

Changing the oil viscosity shifts how quickly a diff couples: lower values give looser, quicker reactions, while higher values increase coupling and mid-corner stability. The 9.000cSt grade is a practical middle ground for iterative tuning and routine refills.

Best practice: clean diff components before use, fill in measured increments to prevent overfilling, and ensure seals are seated when reassembling. Store the bottle sealed, upright, and out of direct sunlight at normal room temperature.
