Just installed my 5100s on my 2015 Chevy 1500. I did the rears a few weeks back and finally did the fronts today. I installed them on the highest setting. Took me a while on the first side but the second was pretty fast. I took it for a drive and it's great. Firmed up the front but in a good way. My wife was complaining about how the front end felt since we've had the truck. Took it down some rough gravel roads, bumps, train tracks and am very happy with them. Going to get it aligned Saturday morning. It felt good but I know with any front end work to get it checked. Now to get my air springs and compressor installed on the rear. Just trying to decide on what to go with.
