Oct 15, 2017  Leaf springs are made up of a series of stacked, curved metal bands that are held together on the end to form a spring.

Leaf Springs. Leaf spring suspensions are much simpler in terms of functionality as the axle is suspended by the spring, and does not require the arduous suspension geometry of the coil-spring set-up. Leaf springs are also much sturdier as compared to the coil springs. They are capable of handling much higher loads with less deflection than coils. Trucks with leaf springs are also easier to raise or lower.

Custom Leaf Springs. Your vehicle’s suspension was built to work with a specific leaf spring and designed to sit your vehicle at a certain ride height. Every year we redesign thousands of leaf springs to adjust the ride height, both up and down, to match what customers would like it to be. And we do this without sacrificing ride quality.

A leaf spring suspension is made of a series of long, relatively thin sections of springy metal attached at both ends to a frame and suspending the axle in the middle. Coil springs look just like one imagines a spring would, and sits on top of the axle or lower control arm and the chassis.
