I hauled my 280# tongue weight trailer 850 miles and I had no problems. They worked great at keeping the vehicle level (no sag at all with about 19psi in them). However, they could have designed the plastic/rubber spacer better. It just floates around the top of the spring and the only thing that keeps it from coming out is the air line. They jounce bumper is easy to remove from the mount. Just pull down at an angle. Getting it out the the coil is another story. I had to disconnect the shock (which is easy) and then pry it out with a long screw driver (not so easy). I hope this helps.

Hi, i did not tried it whit my trailer-tent yet!! It,s gonna be in 2 weeks. But i can tell you that to remove my jounce bumper i did not have to remove my shock. I used water and soap to help me glide it thru the coil. Where i had a little bit more trouble is to pass the air line thru the hole of the support of the jounce bumper and pass the line to make sure that it did not touch the exhaust !!! Dont forget to put rubbers grommets like notlawd says it's very important and dont be cheap on tye-rap to hold the air line in place!!!!! I have pass my air line to go inside the trunk, and i have install a small air tank whit a gauge to have a reserve. The spring valve to fill it up is inside whit the gauge !! I think it's nice and more practical !!!!!!

Thanks for replying so quickly. I notice that the jounce bumper mount appears to have a metal collar piece and I was wondering does that get removed too or just the rubber mount? I'm pulling a 10' Coleman popup and there's just too much sag when I get it all loaded up. And I don't think I've got that much weight in the back either. I'm hoping these will do the trick.

Hi, Yes you have to remove the metal piece on top of the rubber bumper. There's a bolt in the middle of it, just remove the bolt and it will fall. Before you remove the bolt make sure that you have remove the rubber bumper before. This way it's gonna be easier to pass it thru the coil !!! After you are gonna pass the air hose thru the hole of the bolt that you have just remove.
Me i'm pulling a 10' starcraft popup and when i'm loaded it's almost 2700 pounds!! I will try it next week for the first time whit the air spring!! Me to the problem was to much sag.

Just an update on the airspings. 5 months of use and no problems. Not only are they good for towing heavy tongue weights, they are good when traveling with a lot of cargo. Keeps the Sant Fe level no matter what the load is and improves ground clearance.

Plan to order from truckspring.com for $101.59 for self-install on 09 Santa Fe or have Les Schwab do all for #219.30. Appears Air Lift does not offer kit for 07-09 . Appreciate advice on where to drill for inflation valves, psi for when not carrying load, etc. Appears that kit now includes rubber grommets but called "flat washers"?

I placed the valves on the 7-pin elec. hookup mounting bracket. One on each side above the plug, I run about 7 psi when not towing and 12-18 when towing. Make sure you keep some pressure above 5 psi at all times to avoid damage to the air bags.

Decided to have Les Schwab install and glad I did as took them a long time. They used existing holes behind left rear mud flap for valves as I do not have bracket mentioned by notlawd. Very slow leak on left bag so back to Schwab soon. They had great difficulty removing jounce bumpers and did not like the sharp angle the air line has to take coming out of the mount, and if this results in pinching, they want to install a right angle fitting at no extra charge. As others have mentioned, be very careful adding air to these low pressure bags, as you will overinflate almost instantly with a compressor.

I concur with you on the issue regarding the angle of the line as it comes out the jounce bumper and pinching the line. The instructions do not accurately reflect the angle of the suspension arm in relation to the bag and coil spring. I am having to replace one of my bags due to the line finally splitting because of the pinching and a small leak developing from the valve on top of the bag. I'm going to try and enlarge the hole where the jounce bumper bolt threads into and hope that this provide more flexibility in the line as the coil spring is compressed and eliminate the pinching issue with the air line.

for regan9663 etal. Les Schwab had to drill a 3/8" hole to reduce the pinching, they fixed the leak on the left side. and no more leaks after two weeks, but I have my fingers crossed. Now I have fairly loud creaking in the rear which may or may not be the air bags since I am more sensitive to rear noises after the air bag installation. I wonder if anyone else has noticed this noise. I carry 11psi in the bags when not pulling the trailer.
