Liftmaster 41c4220a Gear and Sprocket Kit for Chamberlain, Sears, Craftsman and LiftMaster 1/3 and 1/2 HP Chain Drive Models

This kit saved me a LOT OF MONEY. I figured I was going to have to buy a new garage door opener, until I started watching some YouTube videos. The replacement parts are of excellent quality. If you watch the repair videos on YouTube, you can replace your gears in 10 - 15 minutes with very little effort.

We were a little nervous about ordering this part online, but I am so glad we did! It was exactly what we needed, got here in 2 days and is great quality.

Just what I needed! Installed quickly.

Very easy to replace. Arrives faster than expected

Had everything i needed. works great now

It fit and worked perfectly. Delivery was a promised and instructions clear enough for anyone with very basic mechanical skills to install.

Old gear was sheered off and this kit replaced the metal sprocket that was sheered. Took 30 minutes to install and the garage door is again working.

Fixed the garage door perfectly didnt have to pay for repair man.

Worked great! I used you tube videos to install it. I only had to use the main gear and the grease, i reused all the other ones as they had no wear.

Fit as expected. Saved me a good amount of money.
