The Genie 37558R.S Belt Drive Sprocket Assembly is a genuine OEM replacement component for select Genie belt‑drive garage door openers. Positioned at the top of the opener head, this sprocket transfers motor power to the drive belt, helping restore smooth, quiet travel and dependable door movement when the original sprocket is worn, chipped, or noisy. It’s an ideal fix for belt slippage and rough operation on residential Genie belt‑drive models that specify part number 37558R.S in their parts list or owner’s manual.
This model‑specific sprocket assembly is engineered to fit designated Genie openers and is not universal; confirm compatibility by matching 37558R.S to your opener documentation or unit label. For installation, disconnect power, release the door from the opener, remove the opener cover, replace the sprocket assembly as directed by Genie service instructions, and re-tension the belt per the manual. After reassembly, recheck travel limits and safety reversal, and perform a full door balance and force test. Suitable for residential garage door opener repair and maintenance, this OEM part supports reliable performance and long service life when installed and adjusted correctly.
