Arrowmax am-210029 Silicone Diff Fluid 59ml 60.000cst  [am-210029]

Silicone Diff Oil for RC Differentials

This Arrowmax am-210029 silicone diff fluid is a purpose-built RC-scale differential oil supplied in a 59ml bottle, specified at 60.000cst. It is intended for use inside model car differentials to adjust damping characteristics rather than as a mechanical lubricant for gears or bearings.

The fluid's role is tuning: changing the oil viscosity alters how quickly torque transfers between wheels under load, which affects traction transfer, cornering balance, and throttle bite on scale cars. Use it only inside sealed diffs or gear-type limited-slip units designed for silicone oil.

Installation notes: drain the existing fluid, inspect internal components and seals for wear or contamination, then refill to the manufacturer-recommended volume for your diff type. Work in a clean area and avoid introducing dust or grit into the gearset. Dispose of used fluid following local regulations.

Tuning guidance: start with small viscosity steps when changing diff feel, test on a consistent track surface, and note handling changes before making further adjustments. A higher viscosity generally increases diff locking and mid-corner stability, while lower viscosity promotes quicker torque transfer and freer differential action.

Storage and handling: keep the bottle capped and stored at room temperature away from direct sunlight. Avoid contact with painted surfaces and plastic parts that may be affected by silicone oils; wipe any spills promptly.
