Firestone Ride-Rite Air Helper Spring Kit Rear Ford/Dodge/GM Pickup (W217602071)

Installation required eight 7/16” holes to be drilled into the frame for the upper mounting bracket other than that its a pretty easy install. I drilled two small holes in my bumper on the left side of my tag an installed the air valves there. They are out of the way easy to get to when you are ready to increase the air pressure to carry a load fifth wheel, goose neck etc.. Over all I am very please with the air ride, wish I had put them on sooner
