Safe T Plus Silver is a significant upgrade and well worth the investment. It's huge compared to the stock Ford anti-roll bar. My first test ride was great and there is a noticeable difference in handling and overall steering control. One issue you may have for the DIY crowd is installation. Ford E-450 brackets may not fit due to welds and will need to be ground to fit flush. If you do not like this type of work, I strongly recommend that you install it in the store. If it wasn't for the mount issue I would have given 5 STARS.
