Now I have stock height loaded with 1400 pounds in bed and the ride is great. These things are amazing, I wish I would have installed these 7 years ago. Note that I added the 3/4" white spacer (expanded PVC), I needed a little extra to achieve stock height. I do not know if this is recommended (probably not) but it did not negatively affect the ride. Normally the Timbren is only in contact when loaded. In my case my truck is always loaded as shown in the photo. I chose the Timbrens because I did not care to deal with the potential air leaks of air bags.
