What are leaf springs?

Leaf springs are a basic form of suspension made up of layers of steel of varying sizes sandwiched one upon the other. Most leaf spring setups are formed into an elliptical shape through the use of spring steel which has properties that allow it to flex as pressure is added at either end, but then returning to its original position through a damping process. The steel is generally cut into rectangular sections and then once held together by metal clips at either end and a large bolt through the centre of the leafs. It is then mounted to the axle of the vehicle using large U-bolts, securing the suspension in place. The elasticity of the spring steel allows for a pliancy within the suspension for comfort and control of a car while moving, and a leaf spring setup has been proven as a viable option for cars for many decades, despite only really being found on HGVs and Military vehicles these days.

What are the disadvantages?

A big downside of leaf setups is they aren’t brilliant when it comes to suspension tuning. In racing and performance car applications, it is vital to be able to manipulate a suspension setup for the driving conditions and for different driving styles, something that is much easier nowadays through adjustable coilovers. This lack of adjustability of leaf setups is emphasised by the fact that the ends of the leaf springs are attached to the chassis, which leaves very little scope for shortening or lengthening of the leafs. Adjustments can therefore only really be made through the strength and flexibility of the material used to make up the leaf springs. Leafs also allow very few directions of motion and are only really designed to move vertically, while a spring and damper combination can be manipulated into a much larger range of motion. Leaf springs are firmly clamped together and bolted to the chassis as well as clipped to the axle, thus giving little to no scope for any other direction of motion which can lead to heavy wear on the joints and connections holding the setup together. This connection with a live rear axle can cause comical dynamic characteristics in a car when compared to a more modern independent suspension setup, something that older Mustangs are famous for. The rear axle will simply bounce around high speed corners as the suspension and axle are forced to move around together, when a modern damped system would add much more composure to the driving experience In comparison with a helical spring, leaf springs are generally much stiffer simply down to the steel construction and the tight package that they are bolted and clamped into. Ride comfort is therefore not a feature of vehicles that use leaf springs which made their popularity decrease dramatically after proper dampers were introduced in the 1970s to everyday cars in a cost-effective manner.
