VIDEO: Installing new 4400 pound 6+1 rear leaf springs

Don't think I ever shared this. Simply the best modification to the truck for the camper I've done. It's a little rough ride empty but with the camper on, it's excellent. I kept the Firestone air bags for a new reason, Instead of running 80 pounds in them to level the truck, now I put 20 pounds in them as a third center of span support for the frame. The shackle points are a few feet apart and the frame over the wheels is unsupported carrying a lot of weight. It occurred to that if I keep using the air bags, they would act to relieve some of that force on the frame. It may or may not help but I thought it a reasonable conclusion. The truck handles the load so much better, drives flatter and not nearly so bouncy. If you have thought to install bigger springs in your truck, this is the video for you.

    How heavy does your truck/camper weigh on rear axle on the scales.
    Video looks familiar, maybe you posted it a couple years ago?

    My camper tag says 2950 wet. It's had a few things added to it. 200#. Then when loaded with all our stuff, cameras and electronics, clothes, all the canned and other food, My guess is we hit 4000 pounds or there about. most of my camping is down a gravel road but we do hit developed camping. My load rating is 2800, less the tailgate will bring us closer to 3000. My tires are rated 3400# each. Like most, our truck is over loaded by a few hundred pounds. The brakes are inspected and replaced regularly.

    Why not just add the F350 upper overload? I'll admit I didn't watch the video.


    The video is there for people who are interested and thinking about doing some suspension modification to better handle their load.
    The old springs were sagging or flattened and the left side was 1-1/2 inches lower than the right side unloaded. This solved that problem. Since I was going to replace the springs, I might as well get springs that can handle the load, especially since I regularly haul heavy construction materials and the camper is on the truck for months at a time. It was a winner for me. I plan to install front 3 leaf springs soon. My front left spring is sagging too so that will fix that problem. With the upper F-350 overload spring, the truck still has to drop a bit to engage it. More than what I do with my bigger springs. For me. the bigger spring is the better choice, much cheaper than upgrading to a larger truck.
