I wanted to upsize my tire and this lift allowed me too.

Best pricing I could find. Also offer phone help in choosing.
Measure the cam bolt length before and note it. The 1" setting on the instructions put the front solid on the upper limit metal stop. I'm at 1-3/4" and still have over 2" of lift. Not sure if this is just a 2015 issue or not. I have the torsion bar tool. Did front and back in less than three hours by myself. (air tools) I do think I will need to change to back to a 2" lift or overloads due to the service body on the truck.

Happy with the look
I'm liking how my Silverado looks lifted. Able to get Bigger tires with rims now that its lifted. Ride isn't changed, thought it would be a problem but its fine.
