Abstract: A suspension shock absorber for remote control (RC) cars includes an inner tube and an outer tube coaxial with each other. The hollow area inside the inner tube defines a hollow chamber where a piston and a piston rod slidably moves. A shock cap seals the top of the inner tube and the outer tube. The space between the coaxial inner tube and outer tube is used as an inter-tube bypass route through which bypass oil flows. The shock cap has a bypass passage connecting the inter-tube bypass route with the upper portion of the hollow chamber. A bypass valve in line with the co-axis of the inner tube and the outer tube is disposed on top of the shock cap and used to regulate the amount of oil flow through the bypass passage.
