I disagree....I had them on my 2011 and they were great. Already have the rears on and they take out that harsh ride of the max tow. My truck is a loaded LTZ and I'm sure when my fronts goes on tomorrow it will be improved from my past experience. I also don't plan to max them out only 3rd setting as I tow an RV a lot. Thats where I noticed the biggest improvemnets. Less bounce in the front end while towing and les body roll side to side. To each his own, I'm sure GMC-AT was not happy with his but I suspect his other issues were more to blame then the 5100. Theses shocks have been put on ALOT of trucks over the years and still remain one of the most economical suspension improvements. Some of the other big names mentioned here are great if you offroad and way overkill for the everyday guy imo.
