Are Leaf Springs Better for Towing? The short answer: For heavy duty use and regular full weight towing, leaf springs will almost always outperform coil springs. Why does towing place higher demands on the suspension system? Towing is not merely about pulling a heavy object. When a vehicle pulls a trailer, the rear suspension must…

When inspecting a vehicle’s suspension system, we often wonder: What materials are leaf springs made from? Can specifying certain raw materials help reduce costs during procurement? After all, visually speaking, leaf springs are simply composed of several curved steel plates stacked together—perhaps there’s no need to use high-quality steel. To think that way would be…

When were leaf springs invented? In the 18th century, when horse-drawn carriages still dominated roads, people began using multi-layered steel plate structures to absorb road bumps—a precursor to the leaf spring. The leaf spring we’re familiar with didn’t emerge suddenly; it gradually matured through continuous improvements. The Age of Carriages In 18th-century Europe, stone-paved roads,…

In fact, many people only realize they don’t know what size leaf springs they need when they need to replace their vehicle’s suspension system. It may seem like just a matter of size, but in reality it involves multiple factors such as length, width, curvature, and load capacity. It is crucial to note that selecting…

How are leaf springs manufactured? Leaf springs may seem like nothing more than a simple stack of curved steel plates, but we want our customers to gain a deeper understanding of our product. I. Material Selection Material properties determine the upper limit of service life. The first step in manufacturing a leaf spring is selecting…

Does your vehicle feel more unstable when turning compared to before? It’s very likely that there’s a problem with the sway bar connections. Installing sway bar links yourself is straightforward—most vehicle models can be done independently with the right tools and proper procedure. When should the sway bar links be replaced? The obvious signs are actually…

The sway bar is a seemingly minor component of a vehicle’s suspension system, and many people only become aware of its existence during chassis inspections. So, what does a sway bar do? Is it really that important? What consequences would arise if it were damaged? Let’s discuss this in detail. What is a Sway Bar?…

The rear axle of a truck that is frequently overloaded may experience slight collapse; consequently, many consider adding a leaf as an effective solution. This method is occasionally employed for truck leaf springs and certain trailer leaf springs: instead of replacing the entire spring assembly, a new leaf is added to the existing set to…

Regarding this frequently asked question by our engineers, we must emphasize one key point: most damaged leaf springs cannot be repaired and should be replaced promptly. Leaf springs are high-stress components; any damage must be handled with extreme care, as it directly affects the stability of your truck or trailer and consequently impacts driving safety.…

We need to determine how the sound originates. Under normal operating conditions, slight displacement occurs between the leaf springs in the leaf spring suspension, but this sliding movement does not produce noticeable noise. The common causes of noise generally include: Sand and silt enter the gaps between the blades. Dust and mud enter the system, coming…
