I have a 2004 Silverado 1500 Extended cab regular bed with a 4inch lift. It now has a few miles on it and the leaf springs have seen better days. I need to replace them and wonder if i can swap them out for a set of 1500HD leaf springs.

so will the 1500HD leaf springs fit on a regular 1500?

 

Do you have a set you can measure up? That might be the best way to find out for sure...

 

The nice thing about leaf springs is you can add or subtract a leaf depending upon usage and your preference. More than likely the HD parts will fit,but you may only need to add a leaf or two, for your truck. Once you lift it, there's no guarantee anything stock will be your personal "magic bullet".
