What is true of suspension systems?

1. They have no weight capacity limits

2. They can carry any load without risk

3. They have a manufacturer's weight capacity rating

4. They only support vehicle weight

The correct answer is: They have a manufacturer's weight capacity rating

Suspension systems are vital components of a vehicle, designed to absorb shocks from the road while maintaining contact with the surface. One key aspect of suspension systems is that they come with a manufacturer's weight capacity rating. This rating indicates the maximum weight that the suspension system can safely support and manage. Exceeding this capacity can lead to excessive wear, loss of control, and even catastrophic failure of the suspension components. Understanding this rating is crucial for maintaining vehicle safety and performance, particularly for commercial vehicles that often carry heavy loads. It's essential for drivers and operators to adhere to these capacity limits to ensure safe operation on the road. Knowing the manufacturer's weight capacity also aids in proper cargo loading and distribution, which is fundamental for vehicle stability and handling.
