Liftmaster 41c4220a Gear and Sprocket Kit for Chamberlain, Sears, Craftsman and LiftMaster 1/3 and 1/2 HP Chain Drive Models

Very good for my garage opener. 100% fit on replacement. Thank you. Saved me money to buy a new one.

To repair garage door

Kit was perfect fit for my 1994 Chamberlain garage door opener. Fairly easy installation and a great price for the kit that a local repairman wanted to sell to me for twice the cost.

Excellent product. Fixed my 1/2hp Sears/Craftsman garage door opener. Would buy again!

Just replaced the sprocket/shaft assembly, not the worm gear. Had to drill a new hole in the top flange, but this kit did the job. Plan on rebuilding the assembly I took out with a new sprocket it case my second opener fails. Both are 22 yrs old

Fast shipping and works great

Fast delivery and product is exactly as described.

replacement part

Fast and great price.

Very easy to install. Im glad I only spent the 25 dollars and did not pay to have it repaired or replaced. Wished it was covered under prime! Had to go several days without using remote.
