I purchased these to put on my Chevy Silverado 3500 to help level my load when pulling my camper. Do these installed very easy and did the job very well. The shock itself is of good quality however if there was anyone fault with this, it would be the plastic Key filler connection where I would have preferred to see a brass filler valve T and brass connector instead of plastic. So far no leaks and the ride quality is good. They were a perfect fit and a good value solution for leveling my truck when hauling my camper.

Easy to install and got it early ..

Installed these on a 2005 LeSabre and they fit perfectly and ride well. The OEM Delco part number that GM gives crosses to these shocks - in fact they're the same as the AC-Delcos selling on Amazon for 25 bucks more a pair.The original plastic air lines on the Buick were the snap-on type with a retainer clip and these Gabriels are threaded but Gabriel supplies a fitting kit that makes it a snap (er, I mean, a twist) to install.There was ample length on my factory airlines to attach to these shocks even with snipping off the 90-degree connector that was OEM. NOTE - do not use a flush or diagonal cutters on the plastic airline. The inside diameter is so small (well under a millimeter) you'll crush it. Use an exacto knife and slice it cleanly.There is an included large spring you're supposed to install in the dryer - however I omitted it and figured I'd see how the car performs first. The compressor comes on for a self-check as it's supposed to and then everything levels out. I see no reason to change the spring. Your mileage may vary of course.As for ride comfort, I see little difference between these new ones and the originals. They're a bit stiffer, ever so slightly, but hey they're new. That's to be expected. I saw reviews of the MA822's and it seemed more people said they were stiffer than not and I wanted to keep that large car ride intact as much as possible. No complaints here. Note that I don't have the stiff suspension option (the F41) so maybe for the firm-ride options the Monroes may not be as stiff since the springs are tighter to begin with. With the FE1 soft-ride these are the way to go.Overall these shocks are super and for a saving of nearly 480 over dealer price (535 to install) you cannot beat this set.

Did not lift suspension. Firmer ride with less sway in curve. Seems to be a more stable ride in windy conditions and in curves and turns.

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.
