Find competitively priced Sears Craftsman and Craftsman-compatible replacement gear and sprocket kits for your Craftsman, LiftMaster or Chamberlain operator at Garage Door Supply Co. We have replacement gear and sprocket assemblies for chain drive, belt drive and screw drive Sears garage door openers.
Because Craftsman and LiftMaster parts are divisions of the Chamberlain group, you will find that many parts are interchangeable. For example, our LiftMaster 41C4220A chain drive gear and sprocket assembly can replace worn gears and sprockets on a Sears Craftsman garage door opener, a LiftMaster operator or a Chamberlain opener.
For DIY parts replacement projects on older garage door openers, we have Craftsman/LiftMaster kits designed for operators made between 1984 and 2000. Each kit includes a drive gear, worm gear and bearings to help you replace a nonworking gear and sprocket assembly. With our discount prices on parts for residential Craftsman garage door openers, you won't be forced to invest in a new operator if all you need is a replacement part or two. We only carry new parts made by top manufacturers.
