A+++ Works Perfectly as a replacement for 41C4220A. I removed the part on top, what looks to be a guide. As my opener only had one sprocket, I had to modify the plastic chain guide on my opener so the top sprocket wouldn't hit it. Only took off a little plastic with a dremel. I could of used the sprocket/rod from my opener, but I wanted to use a new sprocket. It is well worth the $.

Just wanted to say thank you for the great feedback and to say that I too used this one as a replacement for the 4220A. Although I went ahead and used the chain spreader and roller too and tossed the old plastic cover.

Item arrived with all components pictured. Seller reused the OEM bag which eliminated the need for wasteful extra packaging. Ball bearing modification appears very high quality and item installs exactly the same as OEM part. In theory, this part should last the lifetime of the garage door opener.

Worked great for my Anaheim Door AD800 which is a Liftmaster. Nice bearing upgrade.
