Air Lift 60821 Air Lift 1000 Air Spring Kit

Best bang for your buck! Easy to install, maybe 20 mins a side. Fully loaded the Flex with camping gear, 2 kids, and a cargo hitch on the rear, could even notice. Ride height maintained, maintained fuel mileage. Awesome price and came early. Be looking into the compressor and set up in future.

The first one was a serious pain to install. After I figured it out and got it in the other side was easy, though. I would suggest having a professional help you out if you have any doubt if you skills. I ran the air tubes to my rear bumper since I would only be using these while towing. Everything turned out great, xx and they work great.

Improved the handling with the trailer and improved gas mileage.

I have a 2010 Lincoln MKS and the springs were getting weak in the back. I didn't want to replace the springs because it would do the same thing again. I did some research and I found out that the OE springs were not made to last. Here is a tip for installing these things. First thing is make sure you have a hole at the top of the spring that goes through the body of the vehicle. If you do not then you are going to have to pull the spring to drill the hole. I was able to install these in 10°F weather without having to undo any piece of the suspension. I didn't even take the tires off. All I did was jack the car up. To make life a HUGE amount easier leave the caps off the airbags and put them in a pot of water and put that pot onto the stove and heat it up. DO NOT submerge the nipples on the end of the airbags. You do not want to get water inside of them. After you have them heated up (I went to almost boiling with the water) take each one out put it on the ground and fold the ends into the center of the bag. Using your knee then kneel on it forcing as much of the air out as you can, then replace the cap on the stem. put it back into the pot of hot water. Do the same for the second bag. The hot water does 2 things. It softens the bag and allows it to bend easier, as the bag cools it is also going to shrink because the air inside is going to get smaller. I took what would have been a multi hour ordeal and got the bags inside of the springs in < 15 minutes. The Lincoln MKS has the typical Ford camber issues in the back of the car. spec states -1° of camber. This will eat up your rear tires. and the problem gets much worse as the springs get soft. the suspension is designed to give more negative camber as the suspension compresses. I was close to -2.5° of rear camber. when I was at -1.5° I installed a set of camber adjustments bolts, these bolts can be purchased aftermarket and are available for most Ford/Lincoln vehicles that have this issue. As the springs got softer it passed the capabilities of the bolts to be able to compensate for... The combination of the bolts and the bags has allowed me to set the car at - 0.3° camber in the rear. When I had the alignment done I told the tech to let the air out of the bags then do the alignment and adjust the camber bolts all the way. then add air to the bags to bring it to the -0.3. You MUST hook up the bags so they are independent if you are trying to correct a sagging rear end

Value for money but my vehicle still sag when i pull my trailer
