Garage Door Opener Gears & Sprockets

Star Door Parts only sells components that were produced by well-known, trusted manufacturers, such as Liftmaster, Sears and Chamberlain. If you need a garage door opener sprocket replacement or just want to upgrade your garage door opener main gears, Star Door Parts has what you need.

The gears and sprockets of a garage door opener are located inside the automated opener so it might be tricky to figure out what you need. Each of the gears is moved by the motorized gear of the opener, and according to many homeowners, the gears can fail swiftly because the small parts frequently handle the entire weight of the door. If you are looking for a garage door opener gear replacement and can’t seem to figure out which piece you need, please give us a call at 952-818-6633. We’d love to help.

Sprockets: Positioned parallel to the main gear, the garage door opener sprocket is a small wheel that features many notches. The chain that lifts the door will be attached to this part. To ensure that the chain moves smoothly along the notches of the sprocket, both the wheel and the chain must be frequently lubricated.

A Kit: At Star Door Parts, we sell numerous sets of gears and sprockets that feature a central bearing connecting the two components. Each of our listings also contains information about the garage door openers with which each part is compatible.

Gears and Sprockets: One of the most common repairs you will need to do on your garage door opener over its life is to replace the white nylon gear inside your garage door opener. We carry this gear in many different kits depending on the repair you need.

If you have any questions about our garage door opener sprockets or gears, please call 952-818-6633. We provide same-day shipping, and once you receive the part, you can view our step-by-step instructions for installing the components.
