Adjusting hydraulic shocks typically involves manipulating the shock absorber's internal settings to change how it reacts to road conditions. In some systems, this is done manually by turning a dial or valve on the shock body to control the amount of damping. In more advanced systems, the adjustment may be electronic, where sensors detect the car’s movement and adjust the fluid flow automatically. For manual systems, the user can increase or decrease damping to make the ride stiffer or softer. Softer settings are preferred for comfort, while stiffer settings provide better handling and control, especially for high-speed or performance driving. It’s important to follow the manufacturer’s instructions carefully to avoid damaging the system or negatively affecting ride quality.
