Truck Suspension

0

A vehicle’s suspension system provides cushion and suspends the vehicle’s body, powertrain, and frame above the wheels. Without the suspension system, your ride in your truck would feel much different, and much less comfortable. Every bump, crack, or dip in the road would be magnified and send shock through the vehicle body.

Suspensions come in different types, solid axel, twin I beam, and independent suspension. In solid axel suspensions, both wheels share the same axel, act as a unit, and is not the most comfortable system. They use springs which help absorb shock, but less so than an independent system. Their biggest advantage is their strength. They offer superior heavy load capacity, are great for off-road use, and handle uneven terrain well.

The independent suspension system supports only one wheel at a time, and is the most popular in vehicles on the road today, as they provide a smooth ride.

Springs are the main part of a vehicle’s suspension system. Available in several designs, most of today’s vehicles use coil springs at all four corners. Different types, such as torsion bars and leaf springs are also available. Leaf springs have a heavier load capacity and usually are found on a truck’s rear suspension system. The way a spring is designed determines how smooth the ride feels, can affect vehicle stability for cornering, and can overload a tire’s grip lowering traction in higher absorption types.

Shock absorbers are another key part of your truck’s suspension system. This part dampens road impact by transforming oscillations of the spring into thermal energy. Without this component, the springs would have you bounding up and down the road like a car in a cartoon. Struts are shock absorbers which are placed inside the spring. This component helps control the speed the suspension is allowed to move at.

Air suspension kits are a little more complicated than standard metal components, are often controlled by air compressors and self-levelling electronics. This type improves vehicle handling, increases performance, can adjust vehicle height, and are great for carrying or towing heavier loads. This system is used on 18 wheelers to help the trucks carry heavier loads and provide increased comfort for the driver.

While your truck’s standard suspension may be sufficient to carry its designed load in the box, suspension modification may be necessary if you are going to be towing your load in a trailer. Several types of weight redistribution hitches are available that can assist handling by redistributing the load forces to both axels.

Each system type, alteration, or adjustment can have an effect on your truck’s towing capabilities, stability, and ride comfort. Failure of various suspension components can cause problems with wheel alignment, tire wear, increase fuel costs, noise, and vibration. They can affect ride height, control of the vehicle, stability, and safety while towing heavy loads. Failure of a component may cause the rear of the vehicle to sag, bang around, and potentially damage other vehicle components. Check components before loading your vehicle. A weak part has the potential of causing you to lose the load, cause a serious accident, or snap the vehicle frame.
