Arrowmax am-210030 Silicone Diff Fluid 59ml 80.000cst, diff fluid for RC differentials  [am-210030]

Silicone diff fluid for tuning

Arrowmax am-210030 is a silicone differential fluid supplied in a 59ml bottle and specified at 80.000cst viscosity for RC-scale differentials. It is intended as a tuning aid for sealed and open differential units used on 1/10 and 1/8 scale electric and nitro models, allowing controlled changes to axle traction and steering behavior without mechanical modification.

Use this fluid when adjusting differential bite and transient response: higher viscosity increases coupling between wheels under load, while lower viscosity permits freer differential action. Applying 80.000cst in one or both sides of a gear diff or ball diff provides a defined mid-high damping characteristic useful for moderate to high traction surfaces and for drivers seeking crisper turn-in and steadier mid-corner balance.

Installation is straightforward for hobbyists familiar with diff service: drain the existing fluid, inspect gears and bearings for wear, then refill to the manufacturer-recommended level while avoiding air pockets. Work the diff through its travel after filling to distribute fluid evenly, and check for leaks around seals or O-rings. This fluid is compatible with typical diff greases and elastomers used in RC differentials but always confirm seal material compatibility if using aftermarket seals.

As a neutral, single-viscosity option, this 80.000cst bottle suits modelers who want a predictable mid-high diff response for a range of on-road and off-road track conditions, keeping setup changes simple and reversible.
