Comprehensive Guide to Leaf Springs
The leaf spring consists of an arc-shaped, slender piece of steel stacked with the same material in smaller sizes and bolted together, creating a reinforced bow-like item. When attached to the rear axle and the chassis, it supports any weight added to a vehicle, preventing the axle from buckling and snapping from the pressure. In the simplest terms, a leaf spring refers to a spring featuring multiple layers of metal bracketed together. They’re essential to the suspension systems of vehicles.
