Arrowmax am-210025 Silicone Diff Fluid 59ml 20,000cst  [am-210025]

Silicone diff fluid for RC differentials

This Arrowmax am-210025 RC-scale accessory is a 59ml bottle of silicone differential fluid formulated at 20,000cst. It is intended for tuning the internal damping characteristics of scale model differentials to influence traction transfer and transient handling behaviour on varied surfaces.

The fluid is presented as a direct fill for open and rebuildable sealed diffs in hobby-grade RC cars and trucks. As a silicone oil it alters how quickly torque is transferred between wheels, providing a predictable increase in diff locking effect compared with lower-viscosity fluids. Use it where heavier diff damping is desired for stability in corner exit or to reduce inside-wheel spin on low-traction surfaces.

When servicing a differential, drain the old oil and refill to the manufacturer's recommended level for the specific differential design. Because this product is an RC-scale fluid, compatibility depends on the differential type and build rather than chassis brand, so verify your differential internals before choosing a viscosity. Store the bottle upright and keep the cap sealed to avoid contamination.
