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

RC differential silicone fluid for precise tuning

The Arrowmax AM-210058 bottle holds 59ml of silicone differential fluid rated at 9.000cSt, formulated for hobby-grade RC car differentials. It influences how torque moves between wheels and helps you dial in cornering balance during setup sessions.

Adjust diff behaviour by changing viscosity: lower cSt gives freer differential action and quicker transient response, while higher cSt increases coupling and traction. This 9.000cSt grade is sized for regular top-ups and small tuning steps without wasting fluid.

Practical handling notes: clean diff housings and bearings before filling, add fluid in controlled amounts to avoid overfill, and reassemble the unit carefully to preserve seals. Keep the bottle capped and store at a stable room temperature away from direct sunlight.
