Leaf springs are one of the oldest kind of springs used for a vehicle’s suspension. (How old? Well, there are examples of leaf springs dating back to medieval times.) You may have also heard them called cart springs or semi - elliptical springs. They are a thin arc of spring steel in rectangular cross sections, attaching the vehicle body to the axle. Leaf springs can serve a damping function as well as a springing one. Although the design is old, it still does the job of spreading the load over the chassis sometimes better than the newer coil springs do. They are often used in commercial applications, but they have also found a lot of use by off - roaders who love to prowl the local trails. This time - tested design puts up with the abuse off - roading can dish out. If your 1984 - 1993 Jeep Cherokee needs to have the leaf springs replaced, we have the perfect part for the job.
