For Scale RC Differentials - 59ml 30,000cst Silicone Oil Arrowmax am-210026  [am-210026]

Setup-focused silicone differential oil

This Arrowmax am-210026 product is a 59ml silicone diff fluid specified at 30,000cst, intended for use inside model differential housings to influence damping and traction without changing gears or spider parts.

Tuning role: fitting a heavier silicone fluid raises internal damping and shifts how torque is shared between wheels, which affects corner exit traction and the car's mid-corner balance. Use this weight to achieve a more stable, less reactive diff feel versus lighter oils.

Compatibility and fit: the fluid is suitable for standard R/C differentials that accept silicone oil. Check that your diff housing is specified for silicone-based fluids and obey your chassis manufacturer's recommended fill levels to avoid leaks or binding.

Installation and handling: dose a small amount through the diff fill port or while rebuilding the unit, rotate the gears to distribute oil and free trapped air, then reassemble. Remove any excess oil from surrounding parts and keep the bottle upright with the cap closed.

Practical tuning tips: 30,000cst is best when you need pronounced internal damping to tame wheelspin on grippy surfaces or to reduce inside-wheel rotation in tight corners. Adjust shocks and roll bars in concert with diff oil changes and log each setup so you can compare lap-to-lap effects.
