The truck rides like a half ton. I will always do shocks as the first upgrade on my next Super Duty’s. They improve the appearance of the truck as well!

FOX shocks on my 2019 Super Duty
These things are a must for the Super Duty trucks! Improved the rear end ride and it feels like its a more planted truck. Easy install, did it with my 5 and 2 year old in about a half hour!

Best ride yet
New shocks were installed along with new tires and a new BDS lift. Hard to tell which component should get credit for the improved ride but I've gone from a stiff ride, reminiscent of a Wells Fargo stagecoach, to a comfortable and responsive ride that handles like I've always wanted but never did. Odds of chipping a tooth when hitting a pothole have gone down considerably.
