Arrowmax am-210038 110ml Silicone Shock Fluid 400cst for RC Dampers  [am-210038]

Fine-tune damping with silicone oil

This Arrowmax am-210038 silicone shock fluid is engineered for hobby RC damping systems. As a silicone-based oil it keeps a consistent, shear-stable viscosity to control rebound and compression in small-scale dampers, helping you refine handling without changing mechanical parts.

When servicing or rebuilding shocks, drain the old fluid, check seals and pistons for wear, then refill to the correct oil level for your damper assembly. The 400cst grade is a medium-high viscosity suited to firmer damping setups where slower piston travel improves stability.

Handle the bottle on a clean surface, avoid contaminating the oil with dirt or threadlocker, and wipe any excess from shock bodies after filling. Dispose of used fluid according to local rules for synthetic oils and keep the bottle upright in a cool, dry place out of direct sunlight.

Performance notes: viscosity choice works together with piston hole size, spring rates and mounting geometry, so alter only one factor at a time during setup checks and record lap times or handling notes to compare changes accurately.
