EASY to install

I have installed these on 4 GM cars and I am very happy with the results. The first set I installed in a 1978 Olds Custom Cruiser wagon back in 1984. I still drive the wagon. The shocks seem to last about 11 years in Arizona, slightly longer than OEM air shocks. When they fail, after about 11 years, it's because they develop a slow air leak that gradually gets worse. Gabriel has a Lifetime Warranty on these, so use the warranty if you keep you cars like I do.These days when I install these shocks I also replace the coil springs, which tend to loose their height over the years. I like the variable-rate springs better than the original fixed-rate factory springs. For GM B-body wagons I like the Moog CC623 springs best. You will need new rubber isolators for the top and bottom of these springs, Moog k6203-2 (2 in a box).If you are replacing air shocks on a Chevy, Buick or Cadillac that had OEM air shocks for ALC, (Automatic Level Control), you will want a way to tie into the original air line, assuming your compressor is still working. This is because the ACDelco air shocks used a unique left shock with a built in "Tee" to send air to the right shock. So get a Monroe AK16 accessory kit, which is basically a "Tee" that accepts the air line tubing size. The OEM tubing and the Gabriel tubing are slightly different, but the Monroe "Tee" works with both sizes. Once you get this setup working with the ALC compressor, you can adjust the trim (rear-end height) with a 10mm wrench on the sensor lever mounted above the rear axle.All this stuff is available on Amazon, and at very reasonable prices. So if your rear end is dragging, or you do a lot of towing, this is the way to go.

Easy to install in about 30 minutes, no issues. The air shocks give me the stance on the 442 I was looking for. Additionally I was looking to improve the 442's stability. I have the air in the shocks at about 80 psi so the ride is a little rougher, but the shocks really help reduce body roll and bounce. Shocks are performing exactly as I was hoping and expecting. After driving the car for over a month, the air pressure in the shocks has remained steady, no leaks. Make sure you have access to an air compressor that has the power to be able to produce enough pressure to air these above 50 psi.

Had these on a 65 impala and was really happy with them. Easy to install, Shocks held air well and the car looked great. Went to put a new set on a 68 Chevelle and the mounting stud sheered off on one side and the nut wouldn’t even begin to thread on the other side. Expected better hardware. Hopefully it was a one off

Haven't been time tested yet, but initial impression is they work like a charm at an unbeatable price. The bolts for the bottom provided less spacing than originalbut that didn't seem to be an issue (you could use originals otherwise).They are about 1/4" diameter larger than the stickers and that was enough to interfere with my aftermarket 3" exhaust just barely, but I was able to reposition the exhaust out of the way. It's close but it will do.The only thing I wish is that they'd have worked with the original plumbing, but you can't knock them because all the others I've seen are the same way and I suspect if you want truly OEM fitment you have to be willing to pay quite a bit for it.

While they do lift the car, by nature to get them to lift to max capacity, it takes a lot of pressure, 200lbs which most compressors can not deliver. Also you need an air gauge that can register high pressures. I needed new shocks so the lift was like a free bonus. One way around that is jack up the car, fill shocks then let down the pressure will be greater in the shocks.A better solution for a lift is to use the red polyurethane air lift 1000 bags. They max out at 35psi and support the lift from inside the spring, especially good if your frame is badly rusted, according the buick forum. However, that much rust compromises the car generally.

These were perfect for fitting my new fat tires and rims on the rear of my 1970 GTO. They were a pain in the caboose to install, no blame to the shocks or seller. Perfect addition to my ride!

I'm sure the shocks are good but I will never know because it was missing parts like the line the fittings everything
