Springs
Springs form the foundation of every suspension system. They support the vehicle’s weight, absorb shocks, and keep the wheels in consistent contact with the road.
A spring is a key component of the suspension system, responsible for bearing the vehicle’s load and absorbing bumps from uneven road surfaces. This not only improves driving comfort but also ensures optimal traction and vehicle control.
In commercial trucks and trailers, the most common types are leaf springs and auxiliary springs. Leaf springs are composed of multiple layers of high-tension steel that flex under load and distribute force evenly. Auxiliary springs are often paired with air suspension to provide additional support when carrying heavy or shifting cargo.
Worn or broken springs can cause chassis misalignment, uneven ride height, excessive axle stress, or premature tire wear. Regular inspection for cracks, corrosion, or sagging is essential, especially in heavy-duty or long-distance operations.
