Arrowmax am-210025 59ml Silicone Diff Oil 20,000cst for RC Differentials  [am-210025]

Silicone oil for precise differential control

This Arrowmax am-210025 item comes as a 59ml bottle of 20,000cst silicone diff fluid intended for RC-scale differentials. It is formulated to modify the internal damping of model diffs, influencing how torque moves between wheels and how the model reacts during quick handling transitions.

The product is supplied for direct filling of open diffs and rebuildable sealed units found in hobby RC cars and trucks. As a silicone fluid it increases damping compared with lower-viscosity oils, producing a more pronounced locking effect that can stabilise corner exits or cut down inside-wheel spin when grip is limited.

During a diff service, remove the old oil and refill to the fill height specified by the differential manufacturer for your particular design. Compatibility is determined by diff construction rather than chassis make, so check your internals before choosing viscosity. Store upright and keep the cap tightened to prevent contamination.
