80.000cst Silicone Differential Fluid 59ml for RC Differentials - Arrowmax am-210030  [am-210030]

Adjust diff damping with silicone oil

Arrowmax am-210030 is a 59ml bottle of silicone differential fluid rated at 80.000cst for RC differentials. It is intended as a tuning aid for sealed and open differential assemblies on 1/10 and 1/8 scale electric and nitro models, allowing drivers to refine traction and steering feel without replacing mechanical parts.

Changing viscosity alters how the driven wheels couple under load: a higher value increases coupling and firmed steering response while a lower value promotes freer differential action. Using 80.000cst in one or both sides of a gear diff or ball diff yields a mid-to-high damping profile that suits medium to high grip conditions and drivers wanting improved initial turn-in and steadier balance through corners.

Service is conventional: drain old fluid, inspect gear and bearing condition, then refill to the manufacturer-recommended level while working the diff to eliminate trapped air. Check seals and O-rings for any signs of leakage. This fluid is broadly compatible with standard diff greases and elastomers; confirm compatibility when fitting aftermarket seals.

As a simple, single-viscosity choice, the 80.000cst Arrowmax fluid delivers consistent mid-high diff behavior ideal for tuners who prefer predictable setup changes.
