Air Lift1000 Air Suspension Kit 60742

Very easy to install to my 1997 Infiniti QX4. Works very well at keeping the rear suspension from bottoming out when I have it loaded with a motorcycle. Would definitely recommend and use these on future vehicles.

Worked perfectly and shipped just in time.

Just left the bags at the max 35psi permanently, been around 2yrs so far not even a peep. This is what you need if you ever haul/tow anything.

I Installed the Air Lift 1000 kit into my 2002 Pathfinder which was experiencing really sacked-out rear coil springs. Replacement springs were ridiculously expensive and these air bladders were less than half the cost. When just two Adults and a full tank, only 30% max rated pressure is needed to keep her rump standing high and proud again. Interesting, I had always known mine was due for some attention but it took other similarly afflicted Pathfinders seen on the road to convince me to act.Installation was straight forward for me (after a slight detour). This being the fact that the 2002 model has lower spring seats that include a center hole that tantalized me to perform installation similar to some others (not drilling it out to the larger bore). All went well until a week later when, with a sudden brief blast of air, the flaw in the method became evident. I was raising the truck back up on the lift for some other work when the poly tube, feeding air to the bladders, popped off one of them. Upon close examination, it appeared that the bladders, after entering service, (being filled with air) become conformed to their individual springs, a death-grip of sorts. So when lifting the truck, allows the rear axle to extend until hanging by its shock's, this allowed the springs to extend and subsequently pull the Air Lift Bladders alarmingly high off their bottom spring seats. For them to do this they must draw their poly tubing air feed tubes up through the seat holes. In this case the original small hole's close-fit gripped the poly tube enough to restrict their smooth feed through and so popped it off the brass nipple extending from the bottom of the bladder. Furthermore, when dropping the vehicle back down on its suspension, the tubing would not return back down the small holes, but would accordion (pinch) into worthlessness. (I tried this as an experiment).So with my new found knowledge, I decided to reinstall per Mfg instructions including, removing the springs, drilling the holes out to at least 5/8", smoothing out any burrs and then reassembling with extra tubing coiled enough beneath the spring seats so that the bladders can rise and fall when the vehicle is raised the way a service station would (via body frame).Handling is great, even heavily loaded with four adults and gear for the holidays plus a trailer, still only requiring raising pressure to 50% of maximum. A wonderful product to be sure.

The ad and the video state that you don't have to remove the coils but the instructions start by saying "Must remove coils" Then they want you to drill a 3/4" hole for relief of the hose connection. I had to make up a chunk of 3/4" thick piece of rubber to space the air bag off the bottom so the hose was protected because no way to drill said 3/4" hole without an angle drill that can handle 3/4". There's nothing to protect the top of the fragile air bag rubbing against the sharp metal housing of the bumper support that had to be cut out. Videos show a cup spacer made up for this purpose but its not included. I'm looking for another 2 slabs of rubber to slide in there and silicone in place before they pop. When one pops going around a corner on the highway the vehicle could flip. Works great though. Its exactly the right idea to remedy Infiniti QX4 soft rear end suspension flaw but they won't last and since their instructions are impossible to meet the warranty is void.
