Leaf spring is a simple type of spring used in suspension systems. It is also the oldest type of suspension spring that dates back to the medieval age. It is sometimes referred to as a semi-elliptical spring. It carries vertical suspension loads along its arc-shape length of rectangular cross section.

It is basically a long strip of steel that can be bonded with other leaf springs to form a complete set. Depending on the suspension requirements or loads of the vehicle, the leaf spring can be adjusted. Leaf spring can serve both as a damper or shock absorber and also as a re-bounder. This dual function of the leaf spring allows effective cancellation of body oscillations of vehicles.

Leaf spring was the most common suspension spring used in automobiles until the 1970’s when it was almost rendered obsolete by more sophisticated suspension units. However, some pickups and SUVs today still utilize leaf spring. If you are one of the few owners of pickups or SUVs using leaf spring, the Trailmaster add-a-leaf might be the right product for you Trailmaster add-a-leaf allows you to adjust the suspension capacity of your vehicle.
