What are the key components of a vehicle's suspension system?

The key components of a vehicle's suspension system include shock absorbers, leaf springs, and struts, making this the correct answer.

Shock absorbers are crucial for controlling the impact and rebound movement of the vehicle's springs and suspension. They help maintain tire contact with the road, providing a smoother ride and improved handling. Leaf springs are often used in the rear suspension of trucks and larger vehicles, providing support and stability by distributing weight and absorbing shock from uneven surfaces. Struts, which are a type of suspension component that combines the shock absorber and the coil spring, offer structural support and help guide the wheel's motion, improving handling and safety.

Understanding these components is essential for Army Motor Transport Operators, as they contribute to the overall vehicle performance and safety during transportation missions.
