Well I'm a little late in responding, but I have a 2014 Silverado Z71, Double Cab, and I have the Ready Lift 2.25" Level Kit installed on my truck. Yes, it seems the kit is a little on the expensive side, but this is the kit my dealer sells and installs. I thought it was worth the extra few bucks to have my Dealer do the install just in case any issues pop up later. The whole job, including the kit, an allignment, labour, and taxes (I'm in Ontario Canada, and our tax is 13%) was just slightly under $600, taxes inc. Not all that bad, considering the kit itself was about $280.00. I could have saved about $40 on the kit if I bought it elsewhere, but I just bought it through my Dealer.
The quality of the kit is "Top Notch", for what you get.........a couple of aluminum spacers. They look well made and quality machined, but they are still just a couple of aluminum spacers. IMHO the ride is pretty much the same as before the lift kit installation. It is a longer step up into the cab, and I find I am using my step bars a lot more.
The kit raised the front exactly 2.25". The truck to me looks pretty much perfectly level, although it still does sit 1" higher in the rear. This is my first experience with doing any sort of levelling/lifting, and as long as I don't run into any pre-mature failure of my front end components, I'll be happy. It certainly does improve the overall look IMO.
