LiftMaster LM-041A7276 Trolley Wear Pad Kit – Genuine 041A7276 / 41A7276 / 183A163 Wear Pads for LiftMaster & Chamberlain Square-Rail Garage Door Openers
***
Long Description
The **LiftMaster LM-041A7276 Trolley Wear Pad Kit** (also referenced as 041A7276, 41A7276, or superseded part 183A163) is a genuine factory replacement designed to renew the sliding surfaces inside your garage door opener trolley. These durable nylon pads sit between the trolley and the square rail, allowing the carriage to glide smoothly while preventing metal-to-metal contact that can cause grinding noises, jerky movement, and premature wear.
Over years of use, the original wear pads can flatten, crack, or fall out, leaving the trolley to scrape directly on the rail. Installing this kit is an inexpensive way to restore smoother, quieter travel and extend the life of both your trolley and rail. Because it is an OEM LiftMaster/Chamberlain part, LM-041A7276 is manufactured to precise tolerances for a proper fit on compatible openers, making it a smart choice for both professional installers and DIY homeowners.

Included in the Kit
- Four (4) trolley wear pads (nylon sliders) for the opener trolley/carriage
You keep your existing trolley, rail, chain or belt, and motor head. The repair typically involves removing the trolley from the rail, taking out the old pads, and snapping the new pads into place according to the opener’s service instructions.

Compatible Units
The LiftMaster LM-041A7276 Trolley Wear Pad Kit is used on many LiftMaster and Chamberlain residential garage door openers that feature **square-tube rail assemblies** and specify wear pad part numbers 041A7276, 41A7276, or 183A163 in their parts diagrams.
Common compatibility guidance:
- LiftMaster residential openers with square-rail trolleys where the parts list calls out 041A7276, 41A7276, or 183A163 for the wear pads
- Chamberlain residential openers with square-tube rails that list 041A7276 as the trolley wear pad kit
- Many Craftsman-branded openers manufactured by Chamberlain that originally used wear pad part 183A163, which has been superseded by 041A7276
Because this kit serves a broad family of models and exact opener lists can change over time, you should always confirm compatibility by:
- Checking the model number on your opener
- Reviewing the replacement parts diagram in the owner’s manual
- Verifying that your current wear pads are labeled 041A7276, 41A7276, or 183A163, or that those part numbers are listed for your trolley
If your opener uses a square-rail trolley and its documentation specifies 041A7276 or 183A163 for the wear pads, this kit is the correct OEM replacement.
