Frequently Asked Questions (FAQs)

1. What type of suspension is used for heavy vehicles?

Heavy-duty vehicles, such as Class 8 trucks, can have different types of suspensions. These include mechanical steel spring suspensions, mechanical elastomeric (rubber) spring suspensions, or air suspensions. The choice of suspension depends on the specific configuration and requirements of the vehicle.

2. What suspension parts wear out fastest?

Shocks and struts are the suspension parts that tend to wear out the fastest. The constant movement and impact while the vehicle is on the road can cause the piston seal in the shocks to fail, leading to fluid leakage and loss of gas pressure. Regular maintenance and replacement of shocks and struts are essential to ensure optimal suspension performance.

3. What are the components of a suspension system?

A suspension system consists of several components, including tires, coil springs, shock absorbers, rods/linkages, and joints/bearings/bushings. The tires are the part of the suspension that touches the ground, while the coil springs absorb impact. Shock absorbers help dampen vibrations, and rods/linkages and joints/bearings/bushings provide stability and allow for movement.

4. What is the strongest type of suspension?

The rigid axle suspension is known for its strength and load-carrying capacity. It has a simple construction and can withstand heavy impacts, making it suitable for off-roading and heavy-duty applications. The resilience and durability of the rigid axle suspension make it a popular choice for demanding environments.

5. What is the most important suspension component?

While all suspension components play a crucial role, tires are often considered the most important part of the suspension system. Tires provide traction for acceleration, braking, and cornering. They also absorb small bumps and contribute to overall ride comfort and handling.

6. What does a suspension kit consist of?

A suspension kit typically includes all the necessary structural components for a suspension upgrade. This includes mounting hardware, bushings, and either shocks or springs. Some kits may offer additional features such as heavy-duty shock absorbers or a lift kit for specific requirements or preferences.
