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

Wish I had a chance to use it. The product looked great and was exactly what I needed. Unfortunately 20 minutes before it arrived a 150 year old oak took out my whole garage, flat as a pancake. They were kind enough to let me return it.

Just perfect for a 1/2 Chamberlain

Its installed and works. What more could I want?

It works as designed. Learned how to use it from YouTube, not very difficult. After 4 months, no problem yet. Hope it can last for another 7 or 8 years.

My opener is now quiet again. It does take time to replace it. But the instructions made it easy. This is the 2nd one I have done over the years. The first with another Chamberlain/craftsman opener. The same part at Sears parts was $20.00 more.

Just what I needed, No need to buy an entire new garage door opener when this simple repair will probably last another 15 years.

quick shiping good quality parts

Perfect replacement part fit. No complaints at all.

This kit appears to be used in many different openers. The gear stripped in a friends very old Liftmaster. This kit was easy to install and fit well.

Worked great, very nice replacement parts
