Arrowmax am-210022 Silicone Diff Fluid 59ml 7,000cst  [am-210022]

Silicone diff fluid for RC differentials

This compact 59ml bottle of silicone differential fluid provides a predictable viscosity option for RC-scale differential tuning. The 7,000cst rating describes the oil's internal resistance to shear and is used to change diff behavior without altering mechanical components.

Use it when adjusting on-track handling: heavier diff fluids typically slow differential action and can increase rear traction on corner exits, while lighter fluids allow freer differential action for smoother turning. Apply the fluid directly into the diff housing following your model's standard disassembly and filling procedure.

Practical notes: work on a clean bench, use small syringes or droppers for precise filling, and test changes incrementally so handling differences are measurable without changing other setup variables.
