RC Silicone Diff Fluid 1.000cSt 59ml - Arrowmax am-210015  [am-210015]

RC diff oil — low damping 1.000cSt

This Arrowmax am-210015 silicone diff fluid is a low-viscosity product supplied in a 59ml bottle and rated at 1.000cSt for use in RC differential assemblies. It is sold as an aftermarket accessory for hobby radio control models to fine-tune diff behavior.

Function — The fluid changes how torque is passed between wheels, affecting turn-in aggression, mid-corner balance, and how quickly traction shifts. With its 1.000cSt viscosity the oil gives very light damping while maintaining lubrication for gears and bearings inside diff housings.

Compatibility — Intended for diffs that accept silicone oils, including sealed and open-type housings often found on 1/10 scale and comparable models. Confirm your diff seals and internal components are compatible with silicone to avoid seal swelling or other material issues.

How to apply — Start with a few drops per gear pocket when trying this low-viscosity grade. After filling, rotate the drivetrain slowly to distribute the oil and displace air, then verify handling during low-speed runs before full-power use. Use syringes or precision applicators to control dosing and prevent contamination.

Tuning notes — Expect faster transient reactions and more agile low-speed steering than with heavier diff oils. Tweak shock settings and roll stiffness in small increments alongside diff oil changes to achieve the handling you want.
