Liftmaster 041A5807-3, CHAIN AND CABLE KIT, 7', 3/4HP
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.
Common Replacement Reasons
- Original chain and cable is broken or stretched
- Excessive chain noise or rail slap
- Trolley does not move smoothly
- Chain will not hold proper tension on a 7 ft compatible rail

Important Compatibility Notes
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.

Technician Note
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.
Before Ordering Checklist
- Confirm the opener uses a chain drive rail
- Confirm the door height is 7 ft
- Confirm the parts diagram calls for 041A5807-3 or 41A5807-3
- Do not substitute for 041A5807, 041A5807-2, or 041A5807-4 without verification
- Inspect the sprocket, trolley, and rail for wear before installing the new chain
Professional Advisory
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.
Product Q&A
What does the -3 suffix mean on 041A5807-3?
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.
Is this the same as 041A5807?
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.
Can I use this on an 8 ft door?
No. An 8 ft door requires the correct 8 ft chain and cable kit, commonly 041A5807-4 when specified.
Is this for belt drive openers?
No. This kit is for compatible chain drive openers only.
Why would my chain keep loosening after replacement?
A worn sprocket, damaged trolley, incorrect chain length, bent rail, or unbalanced door can keep the chain from tensioning correctly.
