PRODUCT GUIDE

 

*NOT all vehicles with spring packs located above the rear axle require a mounting kit. Some exceptions are the Ford F-250 and F-350 with no factory overloads and Ford E-350 vans. Please call the SuperSprings tech support phone line for more information if required.

Locate the SuperSprings part number for your vehicle in the chart below or from the “Find your Spring” pull down menu on the home page.

Where a Mounting Kit is required, remember to order part number MTKT separately.

If your vehicle has rear leaf springs but is not listed on this site, please contact our tech support line for additional applications.

SuperSprings enhance load carrying capacity, handling and towing.
