Dorman 523-089 Front Lower Suspension Control Arm Bumper Compatible with Select Cadillac / Chevrolet / GMC Models

Took about 20 minutes to do both fronts. Big screw driver all you need...maybe a little lube to go back in, but I did not use anything just a screwdriver to push it up in there "without destroying it". Amazing what these alone do for the ride thru pot holes, speed bumps, and turning corners! Put a set of stock AC Delco shocks on front also (about 30 mins) and this truck rides new!...did all this last summer and its going stong. I also put new bumps on the back (different part #, they are black and longer)...those actually took a little longer because the go onto brackets and you need to take those off to install, but it's simple.

I got these to replace my worn out standard suspension jounce bumpers. Note: these are NOT bump stops. In actuality, they are an active part of the suspension to provide a progressive function to the torsion bar suspension.I wanted the Z71 version because I thought they would be a little stiffer. In my hand they were easy to squeeze. The one good OE standard one I had was very firm.Installation was easy, pry out the old one, use a little lubrication in the form of soap or windex, spit...anything realy, and work it into the frame cup. I use the edge of a flat screwdriver to push the lip into the center with the weight of the suspension on it. Took about 5 minutes each side and I didn't have to jack up the truck.I don't have many miles on them yet, but it does appear to have fixed the unevenness left to right (one was really busted, the other wasn't).

Easy to install on my 01 Sierra z71. Hadn’t noticed my old ones had fallen off/deteriorated at some point in time. Put these bad boys in and was ready to go

Put these on an '02 Chevy Silverado 1500 z71, old 1's were crumbled in half. Pop out old with a flat head screw driver and started the new 1's up in the mount by pushing half in by hand and used flat head to carefully pop other side into place, super easy to do! Others say to "lube/grease" end to pop in and that's a horrible idea. If you do that to get them in real easy, they'll pop out just as easy over a pothole. Hold they hold up awhile! Update review if crumble quickly (dont think they will)

Perfect fit for 2000 GMC Sierra 4 wheel drive. It took about 10 minutes for each side. I did have to jack up the truck a few inches to get them in. I applied a dab of light oil to each one and used a flat blade screw driver to push them in. They raised the front of my truck about 1 inch. No more lower "A" frame smacking the upper frame.

These bumpers were perfectly sized and shaped to the originals and easy to install. They just push/pry into the cup that holds them with tabs! Great quality from what I can tell. Now if they'll just last as long as the old and original ones, they'll be perfect!

Easy to install. Pretty expensive for a simple piece of rubber.

Easy install and back to factory feel
