There are lots of threads on the forum asking about what handling improvements that should be made to an F-53 chassis. I ran across this video that does a really good job of showing all of the potential improvements to an F-53 suspension.
I’ve done the Safe-T-Plus, Koni FSD’s and the rear trac bar, all of which substantially improved things. The video is for the 24K chassis. I have an 18K chassis, so the track bar is a different design

I’m looking at either SumoSprings or the Roadmaster sway bars this year, but probably won’t do both unless I find I need more improvement to handle sway on mountain roads. I’m debating on whether to do the work myself as I did with the improvements so far or find a shop to do it. As I get older more jobs fall into the “write a check” category.
