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

Good price and great instructions

Just what i needed yo replace worn gears on my Craftsman garage door opener. Workes fine now.

Wrong part for my garage door opener. The sprocket was the wrong size, and had to to grind on the metal plate to get it to fit on top of the opener. Would not recommend.

This parts kit is a direct replacement of what was installed in my garage door opener. All parts are there to properly overhaul the sprocket assembly. The install took about 45mins after pulling out the proper tools. There are a couple installation videos over on Youtube and are very helpful to help those of us who do not take these apart for a living.

Item came on time and as specified

Perfect fit for my chamberlain opener. Clear instructions and many YouTube videos available. Quick shipping.

Fixed the problem!

Installed myself about a year ago. Working Great. Looked as sturdy as factory parts I was replacing.

Im sure a lota people are going to call a service tech. I never go that route, with the parts ready to ship and the cost way less than Sears why would I do it any other way.

Worked perfectly
