Drove the setup for over 500 miles (onroad) since install. The reduced ride comfort level was noticeable as expected. I hooked up the FORscan and reset the ride height. The oem setting were all over the place because of the lift which explains why the ride quality suffered. After the reset...
Factory ride was great. Needed clearance and wanted to run 35". Perch collars are the same cost as springs plus I will be adding weight in the bed as I build.
The ride is certainly different. Everything comes with a cost!
Can't answer the caster question. The SmartCap is 210lbs. Will be adding bed slide in the near future.
Building it for daily driver (retired) and overlanding with the family. It road so nice stock, I was hesitant to change out the factory springs but I want clearance. Maybe Ford will build it...
