Scale R/C Silicone Differential Fluid 30,000cst 59ml - Arrowmax am-210026  [am-210026]

High-viscosity silicone diff oil for RC setup

This Arrowmax am-210026 silicone diff fluid comes in a 59ml bottle and is specified at 30,000cst. It is intended for filling model differential housings to change damping and traction behavior without altering mechanical components.

Role in setup and tuning: using a heavier silicone fluid inside the diff increases internal damping, altering torque transfer between wheels and affecting corner exit traction and mid-corner balance. Choose this grade when you want a firmer, more locked differential feel compared with lighter oils.

Compatibility and fit: this product is a general-purpose R/C diff fluid suitable for most scale differential units that accept silicone oil. Confirm your diff housing is compatible with silicone fluids before adding oil, and follow your chassis manufacturer's filling level guidance to avoid overfilling.

Installation and handling: add a measured amount into the diff housing through the fill port or during a rebuild, work the gears to distribute the oil, then reassemble. Work the diff to let trapped air escape before final sealing. Clean any spills promptly and store the bottle upright with the cap tightened.

Practical tuning tips: 30,000cst offers strong internal damping, which can help stabilise power delivery on high-traction surfaces or reduce inside-wheel spin in tight turns. When you change diff oil, also review shock and anti-roll bar settings for predictable balance. Make incremental changes and record settings to compare results.
