The main purpose of a shock absorber in a suspension system is to dampen the oscillations of the springs and provide stability. When a vehicle travels over bumps or uneven surfaces, the springs compress and then expand to absorb the impact. Without shock absorbers, these springs would continue to oscillate, causing the vehicle to bounce uncontrollably.

Shock absorbers work by converting the kinetic energy of these oscillations into thermal energy through hydraulic fluid movement, effectively reducing the amplitude and frequency of the oscillations. This process enhances ride comfort and improves vehicle handling by keeping the tires in contact with the road, which is crucial for safety and stability. This ability to stabilize the vehicle's motion is essential in ensuring a smooth ride and maintaining control during acceleration, braking, and cornering.

The other options do not accurately reflect the main function of shock absorbers: they do not provide structural support, adjust ride height, or connect the wheel directly to the suspension system. Their primary role is focused on controlling spring movement to enhance overall performance and safety.
