US Patent 10981425 Vehicle suspension cage and method of adjustment

A vehicle suspension cage is provided and more particularly a dirt track racing rear axle birdcage style cage having features facilitating rapid suspension tuning and adjustment typically experienced during competitive events to accommodate varying track and handling conditions. A particular advantage is that adjustment of the suspension cage is accomplished without unloading the suspension thereby eliminating lifting the vehicle off the ground or removing the vehicle weight from the suspension. A four-link dirt modified suspension cage configuration embodiment and method of adjustment is provided; however, the suspension cage is adaptable to a variety of configurations and embodiments.
