LiftMaster 41D3483 Chain Kit for 8 Foot T-Rail Chain Drive Openers
The LiftMaster 41D3483 chain kit is a replacement 8 foot chain assembly for select LiftMaster and Chamberlain chain drive garage door openers that use a T-rail. It is commonly ordered when the original chain is stretched, damaged, heavily worn, or missing during a rail repair.
This kit is for an 8 foot garage door application. Door height and rail style matter on chain replacement parts, so this should not be treated as a universal chain for every LiftMaster opener. Match the opener model, rail type, and original parts diagram before ordering.

Technician Note
A chain kit should be matched by opener model, rail style, and door height. A 7 foot or 10 foot chain assembly may look similar but will not tension or travel correctly on an 8 foot rail.
Before Ordering
- Confirm the opener is a chain drive unit, not belt drive or screw drive
- Confirm the garage door height is 8 feet
- Confirm the rail is the correct T-rail style for this chain kit
- Check the original parts diagram for 041D3483 or 41D3483
- Inspect sprockets and trolley wear before replacing only the chain
Professional Advisory
Keep hands clear of the rail, chain, sprocket, and moving door hardware during service. If the opener is noisy, binding, or reversing after chain work, have the door balance and opener travel checked by a qualified garage door technician.
Product Questions and Answers
Is the 41D3483 chain kit for a 7 foot or 8 foot door?
The 41D3483 chain kit is for select 8 foot garage door applications. A 7 foot or 10 foot chain kit is a different length and should not be substituted.
Will this fit every LiftMaster chain drive opener?
No. This chain assembly is used on select LiftMaster and Chamberlain chain drive openers with the correct T-rail. Always match it to the opener model and parts diagram.
Can a stretched chain cause opener noise or travel problems?
Yes. A worn or stretched chain can cause poor tension, rough movement, clicking, or travel issues, especially if the trolley or sprocket is also worn.
Should I replace the sprocket when replacing the chain?
Inspect the drive sprocket and gear area before ordering. If the sprocket teeth are worn or the gear is damaged, replacing the chain alone may not correct the problem.
Is this part used on belt drive openers?
No. This is a chain kit for chain drive opener applications. Belt drive openers require belt kits and related belt hardware.
