How does Truck Suspension System work?

The preeminent part of any car, truck, or vehicle is the Suspension system. It is responsible for the control and giving a quality riding experience to the user. According to Layman’s theory, the suspension system optimizes the resistance between the tires and road surface.

This system allows handling any expected and unexpected situation when driving. If you are looking for the best truck suspension parts, then you must look for the factors like load capacity, ride quality, space, and durability.

On the marketplace, there are many suspension parts available, and all work differently. Each part has its strength, features, pros, and cons. Here we have come with a complete guide on suspension parts, so you can come with the right decision when choosing truck suspension parts.

Independent and Solid suspensions

Solid suspension is also known as live axle suspension. Here you should understand the difference between both two independent and solid suspension.

The independent suspension allows each wheel on the same axle to move vertically independently of others. Nowadays, many modern vehicles have independent suspension that helps to give a smooth ride even in the bumps over the road. Furthermore, IFS has a higher ground clearance and smooth running ride in complex situations.

On the other side, a solid axle connects the wheels with a tube. The entire axle moves on once, but if the bump appears over the road, this directly affects the wheel on the other side of the axle that gives a rough drive. SAS is often considered less complex and more durable than IFS. Additionally, SAS has less ground clearance, and it is preferred for rock crawlers.

Torsion Bars

These are also known as torsion springs, which are not like IFS and SAS. Torsion bars are used in IFS; these are long round bars that work as a spring because of twisting strength. Its one side is mounted with solidity on the frame, and the other side is accumulated with the lower control arm of the front suspension. This used to resists the wheel movements and more likely durable than outlasts the vehicle.

Coil and Leaf Springs

Coil springs are used in both IFS and SAS systems. Today, coil springs are the most common spring used in modern vehicles for many applications. They have variable spring rates; the more spring squeezes, the stiffer it becomes. Coil springs offer a smooth ride and allow the truck to balance the heavy load.

On the other side, leaf springs provide excellent articulation. When leaf springs are used in the solid axle, it offers much wheel hop like coil springs. Moreover, they are highly durable and sag over an extended time. Like coil leaf also has variable string rate and has more than often known as overload springs. The cons of leaf springs are they are noisy and ride roughly than the coil.

Wrapping Up

Depending on the load of the truck, a solid and Independent axle is used. Whenever you buy a vehicle, make sure you’ve inspected the suspension system and your need together. Hence, you can come with the right decision.
