A leaf spring suspension system is one of the earliest systems and features long, arched pieces of steel that flex when needed. The leaf spring system is attached to the frame and a shackle that moves, which allows the length of the spring to vary.

The suspension allows the tires and axles of the truck to move independently from one another, instead of the axle being attached to the frame directly. This helps soften the impact on the vehicle and helps absorb the impact of cracks, bumps or dips in the road.

A truck suspension system is an important feature that’s designed to support the vehicle's weight, absorb shocks from the road and help keep the truck steady. It is made up of parts like springs, shock absorbers and other pieces that work together to manage the bumps and holes in the road. This system makes sure the tires stay in contact with the road, which is important for driving safely.

Leaf springs absorb the motion of the truck, reducing the intensity of shock impulses from the road. They’re made of multiple layers of metal, known as leaves, stacked upon each other. These metallic strips, which gradually decrease in length as they’re stacked up, bend and flex to absorb obstacles from the road.

A coil spring suspension is a common system that is found in the front and back of many vehicles and in the front of some trucks. These systems feature springs that are spiraled and allow for flexibility in the form of bending and twisting. They are the most versatile system.

The suspension also needs to help cushion the ride, so the cargo and equipment remain protected over bumps and other imperfections in the road. Cushioning the ride also helps improve driver comfort, which can help maintain safe and attentive driving.

While the go-to move for a while was to install leaf suspension systems on the rear of pickup trucks, coil spring suspension systems installed on the rear of vehicles became popular when Dodge introduced them on their 2009 RAM 1500s. These systems combine a lot of weight-bearing capability with comfort.

That includes skills needed to service truck suspension systems, which contribute to the handling of a vehicle and its stability while on the road. While the purpose of suspensions for cars and trucks is the same, there are major distinctions between the two systems themselves.

There are several signs that can indicate wear and tear on a truck’s suspension system. Paying attention to these is important so you can catch issues early:

Shock absorbers help to control the movement of the truck's springs and suspension by dampening the motion of the springs. This helps the truck make smooth and controlled movements, reducing the probability of skidding or veering off path. They also improve how comfortable a ride is by absorbing the bumps and vibrations that usually come with uneven road surfaces.

Thanks to Automatic Lubrication System, companies can control and optimize tools and machineries performances, increase accuracy and safety, reduce time consumption as well as lubricant consumption.The impact of Centralized Lubrication System on total manufacturing expenses is large. As a matter of fact, lubrication allows to increase efficiency and reduce downtime and business loss. Non-operational machines produce a cost of ownership, the same applies to employees dedicated to control and test manual lubrication. On the other hand, this automatic system limits the damage done by over-lubrication or under-lubrication, improves effectiveness, reduces energy consumption and environmental impact, prevents accidents and contaminants enteringThe supply of lubricant with Dropsa systems is continuous and automatic, provided by the centralized system while the machine is running, so you can minimize human errors and reallocate human resources time and tasks. In this way, they can help build your competitive advantage dedicating themselves to more value-added activities.

The springs absorb the impact from the road, the shock absorbers reduce the springs' movement to prevent bouncing, and the control arms link the vehicle's frame to the suspension system, helping to maintain wheel alignment.

There are a few different heavy-duty truck suspension types that can be used depending on the application the vehicle is handling:

Improving your truck's performance can involve different strategies, ranging from structural changes to regular maintenance. Here are some tips that can improve your truck's suspension system:

The main components of a truck suspension system include springs, shock absorbers and control arms. These heavy-duty truck suspension parts work collectively to absorb road shocks and maintain vehicle stability.

Be sure to take your truck to a trained diesel technician who has the expertise to diagnose and repair suspension issues. This will ensure your vehicle is riding properly and that you remain safe on the road.

More leaf springs can be added to support more weight. Heavy-duty trucks or other diesel vehicles often feature multiple layers of leaf springs if they have this type of system. Pictured here is a leaf spring suspension setup, which is the most common type of suspension system used on big-rig trucks:

Control arms, also known as "A-arms," play an important role in keeping the wheels grounded, improving traction and allowing for more effective braking by keeping the wheels moving in a consistent linear rhythm, which can prevent excessive up and down movement. By promoting even tire contact with the road, you can help reduce tire wear and extend the life of your vehicle's tires.

Signs of a failing semitruck suspension system include excessive bouncing, drifting or pulling during turns, uneven tire wear, noisy steering and a generally harsh or uncomfortable ride.

Semitruck front suspensions focus on steering control, while truck rear suspensions are designed for stability and load bearing.

Maintaining and servicing the suspension system in trucks is crucial to ensure the vehicle's safety, performance and lifespan. Regular maintenance can identify potential issues early on, which can prevent costly repairs and ensure a comfortable and stable ride.

Torsion bar suspensions feature a narrow steel tube attached to the wishbone of a vehicle that twists around its axis. The tube is also attached on one end to the chassis, and this end does not twist. If a wheel hits a bump, tension gets created when the tube twists. After a bump, the steel unwinds and pushes the wheel down again.

Pickup truck suspension systems are responsible for supporting the load being hauled by the vehicle. Often, these vehicles carry large amounts of equipment or products, so the suspension needs to be durable and reliable enough to handle it.

Truck suspensions also are crucial for providing stability on the road. Since these vehicles are heavier and might also be carrying additional weight, the suspension must be able to help with handling uneven roads. The suspension also helps prevent trucks from tipping.

Automatic Lubrication System is used for a lot of applications and in so many sectors, such as maritime, construction, food and beverage industry, steel factories and petrochemical plants. Typically, the automotive manufacturing industry uses this kind of lubrication for chains, pumps and electric motors.There is no industrial sector that does not need to implement lubrication technique to improve processes and reduce inefficiency.Dropsa lubrication systems and components cover all industry sectors. It is one of the world's major producers of centralized lubrication devices and solutions for small or heavy equipments.

The suspension system in trucks maintains performance by ensuring a smooth ride and vehicle stability, even while bearing heavy loads. It also impacts truck handling, especially when navigating uneven terrain.
