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

It really fits

Better than oem. Dropped in. Directions were awesome. Saved me 400 dollars replacing the whole thing. Definitely buy again.

Awesome kit... Came with everything I needed to get the door working again

Included all the Parts and then some. Did not include instructions, but I found a YouTube video with steps.

Fast delivery. Just what we needed!

Fixed my Sears Craftsman garage door opener that had destroyed this exact gear. Replaced it and made everything work after a few trial and errors with the chain position. MUCH cheaper than buying an entirely new garage door opener.

Got this OEM replacement and saved $$$ over 100 dollars by doing it myself.

Unit itself was Great! Shipping was poor at best!

Installation instruction was great and the kit was complete, no problem whatsoever.

Great
