Arrowmax am-210022 Silicone Differential Oil 59ml 7000cst  [am-210022]

Premium silicone diff oil for RC tuning

This compact 59ml bottle offers a reliable silicone oil option for tuning radio-controlled differentials. The 7000cst rating indicates a high-viscosity fluid that changes internal diff damping without mechanical modification.

Apply this oil when refining handling: heavier fluid increases resistance inside the diff, often improving rear traction at corner exit, while lighter fluids reduce resistance for freer turning. Top up the diff housing after following your chassis manufacturer's normal disassembly and filling steps.

Workshop notes: keep the work area clean, use a fine syringe or dropper for controlled filling, and run incremental tests so you can isolate the impact of diff changes from other setup adjustments.
