Arrowmax am-210039 110ml Silicone Shock Fluid 450cst for RC Shock Absorbers  [am-210039]

High-precision silicone shock oil

This Arrowmax am-210039 silicone shock fluid is supplied in a 110ml bottle and specified at 450cst viscosity. It is intended for filling and servicing shock absorbers on electric and nitro RC cars, letting you adjust damping by changing fluid weight.

For routine servicing, remove the shock, drain the old oil, inspect seals and shock shafts for wear, then refill with the correct volume while taking care to minimise trapped air. Use standard shock rebuild tools and replacement seals; avoid forcing components past their intended fit.

At 450cst the oil increases damping compared with lighter fluids, affecting both compression and rebound characteristics. Alter spring rates and preload as required and test on representative surfaces to dial in handling. Always follow the shock or chassis maker's recommendations for fluid volumes and spring combinations for your model.
