Leaf Springs 48-921 Details

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.

All the leaf springs at TruckSpring.com are made to or exceed OEM quality:

  • Made from SAE 5160 Steel, Same as OEM leaf springs.
  • All raw steel is manufactured by steel mills that use the continuous cast (Stran-cast) process, same as OEM leaf springs.
  • Each leaf from the leaf springs is shot peened to specific intensity and coverage.
  • Each leaf spring is coated to prevent corrosion and rust.

If you have any questions about how to identify the correct leaf spring for your vehicle or need bolts or other replacement parts, call us at 1-800-358-4751.

Customer Q&A - Leaf Springs 48-921


I want to effect the original ride very little but, I want to be able to load 15 to 1800# without a lot of squat ( 2" +- ) . ???

Asked
If you do not want to impact the ride we would recommend a helper spring system like a Timbren Suspension kit or a SumoSpring. They are listed under the Suspension / fixed load support page on our website. They will give you the support you need but will not impact your ride when empty. If you add a leaf, it will always be in contact and will impact the original ride some. The helper spring kits like Timbren and SumoSprings will not.


Does this single leaf spring effect the unloaded ride ? At how much additional weight does it begin to support ?

Asked
This helper spring has a capacity of 2,250 lbs. Because it is always engaged it will stiffen up the ride some when unloaded.


Leaf Springs

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.

Leaf Springs Warranty

1 Year Limited Warranty

On all leaf springs.

What the warranty does not cover

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.

How to get service

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.
