Car manufacturers have come a long way to finding the best solution in improving suspension technologies in heavy-duty trucks. They have scaled from the very basic of springs design to a modern air suspension system with hydraulic shocks.
The peak is yet to be reached. However, today automobile manufacturers are taking another leap to improve the previous suspension system design by adding the latest technology. The technology has added more damping control, improved dampers, and air springs.
It also provides you with a ride height sensor that gives you information on the height position of your vehicle's body. It deploys auxiliary suspension automatically and even have a body roll control sensor that monitors cornering.
Given all these benefits, what suspension system do you think is suitable for your fleet? Keep reading as we dig deep into heavy-duty truck suspension.
Why Do I Need a Heavy-duty Suspension System?
Truck suspensions for heavy-duty trucks perform complex and conflicting functions. They have been much development in this nitch. We all know that a suspension system helps negate the forces a car receives from driving on the road.
However, car suspension technology varies, and they perform different functions. For heavy-duty trucks, the suspension system will help increase the vehicle load capacity and prevent sagging when posed to too much weight.
What Type of Suspension Do I Need?
Like earlier mentioned, the type of suspension system you would need depends on the type of vehicle you drive. When you look between classes 1-9, you would definitely see the category your car falls in.
Heavy-duty cars fall into class 7-8, and they most often tandem-drive axles with a 6x4 configuration. These vehicles can use leaf spring suspension systems because of the amount of weight they handle.
They are best suited for heavy-duty cars, rear-wheel-drive cars, and SUVs than coil springs. However, you would have to sacrifice comfort because your ride won't be as smooth. They can also use a mechanical steel spring, rubber spring, or air suspension system.
4WD flux enthusiasts are always after comfort. Flex is the amount of movement your wheels can have. Flex helps determine whether your wheels are well planted on the surface or off the ground, which influences how your vehicle tilts.
When you consider comfort and durability for your 4WD vehicles, the best suspension to get is either the solid axle or independent suspension.

Others include furniture trucks, and smaller semis also fit into this category. In class 8, you can also see the dump and cement trucks, Kenworth’s Freightliners, and Peterbilt’s, which are the big rigs in the industry.
Therefore, you would need a heavy-duty suspension if your vehicle falls into this category.
All-Terrain Vehicles (ATVs) can use an independent suspension system, specifically the double-wishbone suspension. This suspension system helps maintain traction, hence improving performance on uneven surfaces.
How to Improve the Suspension of Your Vehicle?
For obvious reasons, it is best not to only focus on the interior and exterior of your car but also on the suspension system. Many car owners will not even realize how bad their suspension system is until they experience a bumpy ride.
