What type of suspension system utilizes springs located inside the struts?

The independent suspension system is characterized by its design, where each wheel on the same axle is permitted to move independently of the other. This allows for better handling, improved ride quality, and enhanced traction compared to dependent systems. In an independent suspension setup, the springs are often integrated within the struts, providing a compact configuration that helps optimize space and performance.

This integration allows the struts to provide both the support and damping required for effective suspension performance. Because the springs are located inside the struts, they can easily accommodate the vertical movement of the wheels without affecting the opposite side, which is a distinct advantage of the independent suspension system.

In contrast, the other types of suspension systems mentioned do not typically employ this specific design. Dependent suspension systems link the movement of wheels together, meaning that when one wheel moves, it can affect the other. Leaf spring and solid axle systems also have different structural configurations and do not utilize springs within struts. The independent design with springs inside struts is crucial for achieving enhanced vehicle dynamics and comfort, making this the correct choice.
