Suspension changes to carry ATV in box?
I have a 2007 extended cab Ranger sport 4X4 with the 4.0L. I am wanting to carry a Honda Atv in the box. I think they weight between 500-700 pounds. What altercations should I make to the rear suspension if any? Thanks

When I pulled off my factory bed and installed my flat bed I used a product called SuperSprings. I've been very happy with them. There was 2 choices offered by them depending on how much weight assist was needed, I choose the heavier duty one. Ride stiffened slightly but I like the feel better really.
Welcome to the forum
Rangers are rated as 1/2 ton, 1,000lbs, load in bed, but they can squat in the rear
Look on the drivers door, back edge for the Build Label, take a picture of it for future reference, loads of info about YOUR Ranger here, info specific to this one vehicle
At the bottom right of the label will be the Spring Code, in 2007 there should be just 2 digits, but can be 4
example 1K, 1 is the front spring and K is the rear spring
11KK, 11 are the front springs, KK are the rear springs
The spring code will have a weight rating you can look up
If your truck rides OK now with empty bed then I would put the ATV in the rear and see if it squats too much in the rear, if not then drive it around and see if its too "bouncy"
You can usually fix "bouncy" with better shocks
If it squats too much, or more than you like, then you can add an Overload leaf to each side, its a single leaf spring add to existing leafs, but they aren't used until weight in the bed gets high enough for them to touch the other leafs, so you keep the same empty bed ride but have the higher weight capacity, win-win
If you put in higher weight rated leaf spring then you will get a "stiff" ride when bed is empty, and since most of the time trucks bed is empty its not a good trade off, but this is what they do at the factory, Ford installs higher weight rated springs for extra load capacity, making for a very stiff ride
You can swap these out for lower weight rated springs and add an overload spring to get a smooth ride empty and the extra weight capacity
