Many mechanics recommend using an air gun for shock installation, as it can help speed up the process and reduce the risk of damage to components. It is important to use a torque wrench when tightening any suspension component, such as struts or strut mounts, in order to ensure that they are tightened properly. Additionally, some shocks may require special tools or techniques in order to be properly installed, so it is best to consult with an experienced mechanic before attempting this yourself.
