I have the short bed reg. cab 1997 F150 with a shell. the rear springs are a bit tired (sag a bit on one side and leaves no longer aligned with eachother). I am planning on replacing them but am on the fence regarding which way to go. Either way I will be yanking the old springs and replacing them.
One option is get standard rate springs and add a ~1" spacer to better match the front. This would keep the stock spring rate but raise the rear a bit with all the junk in back such as shell, sleeping platform and gear.
The other option I am considering is replacing with a higher rate spring. This would also raise the rear a bit. I worry that the higher rate springs will influence the articulation in the rear a bit and overall handling when loaded and unloaded.
What direction would you go and why?
