These air springs are great for my 2006 Nissan Pathfinder! The kit contained everything I needed. I made a small custom panel to have the air valves on the back of the car on my hitch. I also installed a double air line instead of one line - TI prefers to have all the air in each individual airbag. . When I've used TI I've heard that air can pass on either side. Finally very easy to install. Took me about 1 hour total. Also, I keep mine at 13 PSI in every pocket for everyday riding.
