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

Silicone shock fluid for RC shocks

This Arrowmax am-210039 silicone shock fluid is an RC-scale damping oil supplied in a 110ml bottle and marked as 450cst in viscosity. It is intended for filling and servicing shock absorbers on electric and nitro RC cars, helping to tune damping response by changing fluid viscosity.

Installation is straightforward for familiar hobbyists: remove the shock, drain existing oil, inspect seals and shock shafts for wear, then refill with the selected amount of fluid and reassemble while minimizing air pockets. Use standard shock rebuilding tools and spares; do not force components beyond their designed fit.

In tuning use, a 450cst fluid typically increases damping compared with lower-viscosity oils, affecting both compression and rebound behaviour. Adjust spring rates and preload accordingly and test on representative track surfaces to evaluate handling changes. Always follow manufacturer guidance for shock volumes and spring pairings for your specific chassis.
