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

Very good kit! Easy to install and my garage door works well. It saved me a lot money from calling repair services.

Worked great. I followed the counsel of others of putting the screws through the holes before installing them to pre-thread them. Worked great!

Perfect description and picture. Made my life easy and saved $250! Dowloaded YouTube video and used this piece to fix my door for good! So grateful for parts and proper descriptions AND great price. Thank you.
