The LiftMaster 041A5807-3 chain and cable kit is a 7 ft door-height drive assembly for select chain drive garage door openers. It includes the chain and cable section that works with the trolley and sprocket to pull the garage door open and closed. A worn chain can cause slapping, uneven travel, chatter, skipped teeth, or incomplete trolley movement.
This part is commonly noted for 7 ft, 3/4 HP chain drive applications that specifically list 041A5807-3 or 41A5807-3. It should not be treated as the same part as the standard 041A5807 7 ft chain kit without checking the parts diagram, and it should not be used on 8 ft or 10 ft rail systems.
Do not order this only because the door is 7 ft high. Some 7 ft chain drive openers use 041A5807, while this row is 041A5807-3. Match the original parts diagram and opener model before upload or customer shipment.

The -3 suffix matters. Similar 041A5807 chain kits may be used on different rail lengths or opener configurations, so match the suffix from the exploded parts diagram.
If the chain failed because the garage door is binding or out of balance, replacing the chain alone may not correct the issue. Have the door balance and spring system checked by a qualified technician.
The suffix identifies a specific chain and cable kit version. It should be matched to the opener parts diagram rather than removed from the part number.
Not automatically. 041A5807 and 041A5807-3 are related 7 ft chain kit references, but the correct one depends on the opener model and parts list.
No. An 8 ft door requires the correct 8 ft chain and cable kit, commonly 041A5807-4 when specified.
No. This kit is for compatible chain drive openers only.
A worn sprocket, damaged trolley, incorrect chain length, bent rail, or unbalanced door can keep the chain from tensioning correctly.
