In suspension context, what does the term "sag" refer to?

The term "sag" in the context of suspension refers to the downward movement of the vehicle frame due to weight. This phenomenon occurs when the weight of the vehicle, including its cargo and passengers, causes the suspension system to compress. As a result, the vehicle's frame lowers, which can affect ride height and handling characteristics.

Understanding sag is crucial for diagnosing suspension issues and ensuring optimal vehicle performance. It helps technicians identify whether the suspension system is functioning correctly or if components such as springs or shock absorbers may be worn or damaged. While other terms relating to suspension travel, adjustability of shock absorbers, and vehicle sway during cornering are important aspects of suspension dynamics, they do not define the specific concept of sag as it pertains to the frame's response to weight.
