Arrowmax am-210026 59ml 30,000cst Silicone Diff Fluid  [am-210026]

Silicone diff oil - compatibility and handling notes

The Arrowmax am-210026 silicone differential fluid is supplied in a 59ml bottle and rated at 30,000cst. It is used inside model differential housings to alter damping and traction behavior without swapping mechanical components.

Tuning role: using a heavier silicone fluid increases internal damping and modifies torque transfer between wheels, which affects corner exit grip and mid-corner balance. This grade is chosen when a more locked or stable differential response is required compared with lighter oils.

Compatibility and fit: this is a general R/C diff fluid compatible with most scale differentials that accept silicone oil. Confirm your diff housing specification for silicone fluids and follow the fill level advice from your chassis maker to avoid overfilling.

Installation and handling: add a controlled quantity into the diff through the fill port or during a rebuild, rotate the gears to distribute the oil and expel trapped air, then reassemble. Wipe away any spills promptly and store the bottle upright with the cap secured.

Practical tips: 30,000cst provides pronounced internal damping, useful on grippy tracks or to limit inside-wheel spin in tight corners. Combine diff oil decisions with shock and anti-roll bar tuning, keep changes small, and log setups to compare lap performance.
