At TruckSpring / Michigan Truck Spring, we obtain our leaf springs from various sources throughout the world. All of the manufacturers that we represent produce leaf springs that are as good as or better quality than OEM springs.
Virtually no vehicle manufacturer actually manufactures their own leaf springs. Like many other truck components, leaf springs are purchased from companies specializing in supplying parts to truck manufacturers. The springs we sell have the same or better quality as OEM springs and many times are purchased from the same manufacturer.
On all leaf springs.
Damage from accidents, corrosion, improper installation, incorrect applications, overloading, and custom applications that are not specified under the OEM cross references. This warranty does not cover loss of freight, loss of profit, equipment, or personal downtime. Any alteration of products will void the warranty. Warranty is void if new u-bolts are not installed when the new leaf spring is installed. Using existing u-bolts is a common cause for leaf spring breakage and failure.
If a leaf spring failure results from a manufacturer defect, contact us at Michigan Truck Spring for support. You can contact us by phone at 1-800-358-4751 or by using our contact form.
