Cliff DowningNovember 7, 2017 at 1:51 am 5 out of 5 Great addition to my 2015 Silverado 2500HD. I had already lowered the back end with a set of McGaughy’s shackles because I couldn’t stand the “cat in heat” look of the back end. I am also getting older and it made getting in and out of the back a much better proposition. Put on the Sumos shortly afterward and they rest right on the axle when empty. When loaded even with a ton or slightly more, very little squat and the ride is like having air springs on the truck. Feels more stable also. Well worth the investment. Highly recommend. So simple and easy to install.
