Which part is NOT part of a truck's suspension system?

Shock absorber
Brake rotor
Spring
Leaf spring

The correct answer is: Brake rotor

The brake rotor is not part of a truck's suspension system. The suspension system is designed to support the weight of the vehicle, absorb shocks from the road, and maintain tire contact with the ground for optimal handling and safety. Key components of the suspension system typically include shock absorbers, springs (such as leaf springs), and various linkages that connect these components to the vehicle’s frame. Shock absorbers dampen the oscillations from the springs, while springs (including leaf springs) are designed to absorb energy from bumps and irregularities in the road surface. In contrast, the brake rotor is a component of the braking system. It is specifically designed to provide a surface for the brake pads to clamp onto in order to slow down or stop the vehicle. This functionality places it squarely within the braking system, rather than the suspension system, highlighting why the brake rotor is correctly identified as a part that does not belong to the truck's suspension system.
