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

7,000cst silicone fluid for RC diffs

This compact 59ml bottle of silicone differential fluid gives a consistent viscosity choice for RC differential tuning. The 7,000cst specification measures the oil's resistance to flow and is used to change diff behaviour without modifying gears or housings.

Apply it when adjusting on-track balance: thicker diff oil generally slows internal differential action and can boost rear traction on corner exit, while lighter fluids permit freer differential rotation for easier turning. Fill the diff housing directly after following your chassis' standard disassembly and filling procedure.

Practical tips: work on a clean bench, use a syringe or dropper for accurate filling, and test changes incrementally so handling differences are clear without altering other setup variables.
