Description
The LiftMaster K15-41B25LGH Drive Sprocket is a replacement drive sprocket for LiftMaster gate operator drive trains, responsible for engaging the drive chain and transmitting motor torque to the gate.
In practical terms, it sits in the chain-drive path and is essential for reliable opening and closing. Use this sprocket during service when the teeth show wear, the chain rides unevenly, or you hear unusual noise during operation. Replacing worn sprockets helps maintain smooth, consistent motion and reduces wear on other drive components in both residential and commercial gate installations.
Compatibility: Designed for LiftMaster operators that use the K15-41B25LGH drive sprocket configuration. Confirm part number and fit with your unit’s service documentation before replacement.
