Perfect fit for 2000 Suburban 1500 4wd with Auto-ride suspension. Easiest way to access is to jack up front, and go in from behind the front tires. Getting old ones out was a bit of an effort as they were crumbling apart as I pried with large flat blade screw driver. But, I finally got them out by jamming the blade down hard behind them and prying. The new ones went in quite easily by angling them to get part of them under two of the retaining "stays", then using the screw driver to compress the bumper material a bit to get it under the other two. For reference, it took me longer to jack up the car and position the jackstands than it took to replace the bumpers.Update February 16, 2019: I can't believe the difference in ride and handling since replacing my deteriorated bumpers. Since mine simply got old and literally eroded away, the ride got more "floaty" over time. My Suburban dipped at stops, and also "rolled" a little too much in the corners. So much so that I had been researching new shocks. But now that the new bumpers are in, the vehicle no longer floats, or dips or rolls excessively, and I actually feel much more in control again. I attribute all this to the fact that the car is meant to sit down on these bumpers, and they are actually a part of the suspension, and not just a bumper that prevents metal to metal contact when bottoming out. It appears that they were designed to work in concert with the shocks and springs. I wish I had replaced them long ago, but every time I jacked up the car to work on it, the suspension would extend so I never realized the car was supposed to ride on the bumpers.In a way, I am glad my auto-ride shocks are so expensive to replace. Otherwise I would have mistakenly replaced my shocks only to find out later that a big part of my problem was the bumpers being worn away. If your bumpers are eroded, I recommend you replace them before you do anything else. It could save you quite a bit of headache, and money!
