This is my second Firestone air bag kit purchase (one of the air bags installed from the old kit was leaking) and all the parts were in the kit. These air bags help keep my van raised and from bottoming out when I have a lot of passengers in the van and when I'm carrying a heavy load. My van unfortunately was built a little too low to the ground. I would definitely recommend this product to anyone that wants additional support for the back of their vehicle. I had my mechanic install the air bags, so I'm not sure how difficult it was to install. Purchasing the air bags from SD Truck Springs was an easy process.
