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

Worked great! Did the job.

Ordered this trying to save money and without calling a professional out. It came fast and in good shape. I started doing it myself and when I got to the removing the old gear, decided to call my brother out to help me. He had it replaced in no time. Saved over 100 doing it myself. Thanks for delivering a great product.

was not like the original had to modify to make it work.

It works.

Excellent product, very simple to replace the part and it was magnificent

Easy replacement and with the included lube, the door is quieter than ever...
