Product Description
The 41C4220A gear and sprocket assembly is ideal when you need to replace parts on your garage door opener. At North Shore Commercial Door, we're proud to carry this comprehensive kit, because it includes all of the commonly worn parts in an opener's drive system. It's very easy to install because it doesn't require you to take apart the output shaft assembly, and the spur gear is already mounted on the new output shaft. What could be simpler than that?

A new bushing under the sprocket, the worm gear and other parts are also included in the 41C4220A gear and sprocket assembly. It's also very affordable, which makes it the smart choice on almost any budget. Because it fits most chain drive openers that were manufactured after 1984, the 41C4220A assembly is ideal for most applications.

The 41C4220A is compatible with:
  • Liftmaster
  • Chamberlain
  • Sears Craftsman
  • Master Mechanic
  • Some Wayne Dalton units
