Hello Rocky, thanks for reaching out. If your new leaf springs do not have as much of an arch as the old springs they are definitely not going to help your situation if your tires are already rubbing on the fenders. What we would usually do here is…

Hello Jeff, I sure can! There are two key pieces of info we will need in order to know exactly what spring you will need. The weight capacity of your axle, and the unloaded eye-to-eye length of the current spring. Try jacking up one side of the…
