I finished installing the new lift kit in my truck and am in the process of clearing out all the remaining parts that were removed or are lying around. I'm looking to unload the leveling kit and shocks that I removed from my truck when I installed the lift kit. They were both on the truck for less than 50 miles(due to tire rub bc the rim offset was too high) and look like new. The keys have some marks on them from installation, and the shocks may have a handful of scratches but overall look great. The lower eyelet on the rear shock was the wrong size(1/8" small), the bolt fits, but sorta has to be threaded into the mount, it doesn't cause a problem, just wanted you to be aware of it. You can easily go to your parts store and grab a new metal sleeve and make it perfect.
I thought they rode better, they absolutely responded better, they may have been a little stiffer. But I have a regular cab/short bed so my truck rides a bit rough to begin with. I was nearing 45k miles when I changed everything out, so it was like night and day for me.
Sorry for anyone who was interested. It's all sold, to the only guy who offered me my asking price. Cost an arm and a leg to ship the stuff, so highest price wins.
