Leaf Springs Important Role

Your leaf springs are one of the most important parts of your trucks suspension. If your leaf springs are shot or showing fatigue from old age, it is recommended to change them both out at the same time. If you only change one leaf spring, it is common that your truck will lean toward the side with the older leaf spring. If you purchase one leaf spring and decided to replace the other one at a later date, you may receive a spring from another manufacturer as we source our springs from multiple manufacturers. It is recommend to replace them in pairs to guarantee a match.

Replacing your leaf springs with a high quality OEM leaf spring from Michigan Truck Spring will help improve your ride in the following ways:

• Less bounce, which means more solid contact with the road and therefore longer tire life.
• Driver comfort is greatly improved.
• Your payload sits tight, significantly reducing cargo damage.
• Smoother ride and less bottoming out.
• Safety! Your truck will handle better which means it's safer.
