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

This part came with everything I needed to repair my garage door. No issues.

This part was relatively easy to install in about 30 minutes and solved the problem with my garage door opener.

Worked out great.

as advertised

Replacement fits perfectly.

worked well on my Sears 1/2 HP opener, Saved over a hundred bucks by doing my own install

Great value, easy install.. complete kit with extra shims etc..

Item as described, works great!

Very easy kit to install, just takes some patience and it works great now.

Worked perfectly. Restored function of an old opener for a lot less than a new one costs. The work took a little time (about 90 minutes for me, being careful and double checking and cleaning everything), but was straightforward and easy. The instructions were very good, especially since they werent written for my opener specifically. Definitely recommend this kit, if your opener has stripped the teeth of the main plastic gear.
