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

Silicone differential fluid for R/C tuning

This Arrowmax am-210026 silicone diff fluid is a compact, scale R/C accessory supplied in a 59ml bottle and specified as 30,000cst. It is intended for use inside model differential housings to alter damping and traction behavior without changing mechanical parts.

Role in setup and tuning: applying a heavier silicone fluid in a differential increases internal damping, which changes how torque transfers between wheels and affects corner exit traction and mid-corner balance. Use this fluid when you want a more locked or stable differential feel compared with lighter oils.

Compatibility and fit: the product is a generic R/C diff fluid suitable for most scale differential units that accept silicone oil. Confirm your diff housing uses silicone-based fluids before filling, and follow your chassis manufacturer’s filling level recommendations to avoid overfilling.

Installation and handling: apply a small amount into the diff housing through the fill port or during routine rebuilds, work the gears to distribute the oil, then reassemble. Allow trapped air to escape by cycling the diff before final reassembly. Clean spills promptly and store the bottle upright with the cap secured.

Practical tuning tips: use 30,000cst when you need strong internal damping—this can help stabilize power delivery on high-traction surfaces or reduce inside-wheel spin in tight corners. Combine changes to diff fluid with shock and anti-roll bar adjustments for predictable results. Make incremental changes and log settings to compare lap-to-lap effects.
