The leaf spring is an uncomplicated type of spring, which is basically utilized for vehicle suspension. For heavy vehicles, the leaf spring can be designed from a number of leaves heaped on top of each other in quite a few layers, always with methodically shorter leaves. The Pro Comp leaf springs can function locating, damping services and springing purposes to some degree. Leaf springs are crafted in two styles, and they are the mono-leaf and the multi-leaf.

One example of the mono-leaf spring is the tapered leaf spring. The leaf shrinks down toward the two ends and is often bulky in the middle. The multi-leaf, on the other hand, is made up of a number of steel plates; each with dissimilar lengths all piled one after the other. All throughout standard procedures, the spring compacts to soak up road shocks.

The leaf springs slither and curve on each other, which permit suspension movement. The leaf springs can be found fastened over the front axle beam or beneath the rear axle housing. The spring center bolt or lock attaches the leaves collectively. Its head situates the spring in the saddle, the rear axle housing, or the front axle beam. The U-bolts grip the spring securely in place and to keep the springs from moving. Shackles, brackets, and eyebolts fasten the springs to the frame at every end. Leaf springs also function as control arms, transmitting force to the chassis and positioning the rear end in place. It is a normal sight for applied leaf springs to drop down from 0.5 to an inch during the initial 500 to 1000 miles of service. Pro Comp leaf springs will supply more lift than indicated and if dropping down happens, it means it is within service qualifications.
