A modified strut does not include a(n) _______ as part of the assembly.

A modified strut typically does not include a spring as part of its assembly because the design of a modified strut is intended to utilize a separate spring system. This approach allows for more customizable performance, where the spring can be chosen based on specific handling and ride quality needs, rather than being integrated directly into the strut itself. By not including the spring, the modified strut can focus on optimizing other aspects such as damping characteristics or clearance, providing the vehicle with improved handling and ride stability.

The absence of the spring also means that changes to the suspension setup can be made more easily, allowing for adjustments without the need to replace the entire strut assembly. In contrast, the other components mentioned are commonly included in a modified strut assembly, as they are essential for mounting the strut to the vehicle and protecting its internal parts from debris and contaminants.
