Car and Truck Leaf Springs

These are semi-elliptical arms manufactured out of steel or composite materials that support the weight of a truck or a car. These parts form the suspension for most heavy-duty vehicles, including vans and trucks and even sports cars. An understanding of the operations of a leaf spring can aid you in maintaining your vehicle and keeping it working correctly.

What is the purpose of leaf springs?

They are an important component of the car's suspension system and absorb energy as the car moves across uneven terrain by helping the tires maintain close contact with the ground. They are similar to torsion bars and coil springs. They help to control chassis rolling and axle dampening while protecting the car from lateral forces. Leaf springs help passengers to enjoy a smooth ride and improve the handling of the car.

What are the benefits of having a leaf spring?

The leaf spring system was originally used because of the simplicity of its design, based on bundles of steel. They also help to distribute the load across the whole chassis as opposed to a single insertion point. They are sturdy and capable of withstanding significant weight.

What are the different types of leaf springs?

They come in four different types based on their shape and the material used in making them. These include the following:

  • Fiberglass or steel: These are the lightest type as they are made of resin and plastic fiber. This is particularly recommended for those who want to enhance the performance of their automobile by reducing its weight. The steel type can withstand road debris and heat.
  • Mono-leaf: This type contains a single steel plate which tapers on both ends. This is a lighter alternative to multi-leaf construction.
  • Multi-leaf: Its design brings together flat bars of decreasing lengths into bundles that are clamped together using clips and bolts. Every leaf has a specific length that holds up the strip above it, thus providing additional support for the system. These springs are a great choice for big vehicles that need to withstand extra loads.
  • Parabolic: This type brings together the features of a multi-leaf and a mono-leaf spring into a parabolic curve. The design combines multiple tapered steel plates into a single bundle.

What can you consider when selecting leaf springs?

  • Heavy duty or stock leaf springs: The stock springs are recommended when you want to restore your vehicle to its original condition after the springs have been stretched out over time. On the other hand, the heavy duty type is recommended when you want to increase the capacity of your vehicle.
  • Differences in leaf springs: They are different types of springs. Some are modified to enhance their performance. For example, some have an improved clip design which has metal riveted clips as well as clip bolts.
