Arrowmax am-210040 Silicone Shock Fluid 110ml 500cst for RC Cars and Buggies  [am-210040]

Model shock damping oil overview

Arrowmax am-210040 Silicone Shock Fluid is supplied in a 110ml bottle with a nominal 500cst viscosity for use in model car and buggy shock absorbers. This product is a clean silicone oil intended for shock maintenance and performance tuning and is not for any full-scale vehicle application.

The fluid's purpose is damping control: altering viscosity changes compression and rebound response inside threaded or cartridge-style shocks used on electric and nitro RC cars and buggies. A 500cst grade typically yields a moderate damping characteristic, favouring steadier rebound without overly stiff compression on many setups.

Installation and handling are the same as standard shock service: remove old oil, inspect pistons, rods and seals, then refill to the recommended level for the shock. Perform work on a clean bench, use correct caps and rods, and seat pistons to avoid air pockets. Dispose of used fluid in line with local waste requirements.

Tuning practice suggests altering a single parameter at a time—oil viscosity, piston configuration, or spring rate—so you can measure effects on roll, pitch and traction. Take temperature and runtime into account as they will influence damping feel during tests.
