Review on 10 Pack Blue XiKe 2-Inch Nylon Garage Door Roller with 4-Inch Stem - Quiet, Durable, High Load - Featuring 6200-2RS Double Seals Precision Bearings by David Guliford

I replaced one door with a set of these and compared them to a second door that had solid metal casters and the difference between day and night is obvious. As soon as I made the first door I ordered another set for the second door and I believe it arrived the next day. Really very cool wheelset, super quiet and very smooth-running. I highly recommend this set. Each door took about 30 minutes or so. Just remember that the bottom wheels on each side will hold the load, so you need to make sure the garage door is up when you do it. I also recommend doing one side at a time. If you are still hearing noise after installing these wheels you may want to lubricate your pulleys as I noticed mine are making noise after not hearing the noise from the wheels. I hit all four pulleys on each door with WD-40 and all was quiet.
