If you want to see how replacement parts fit together on your LiftMaster GH, visit our LiftMaster GH Exploded Parts page. When gears become worn or gummed up with dust or debris, replacing a gear part is much less expensive than ignoring the problem until your garage door opener must be replaced.

Our easy 30-day return policy means you won't be stuck with a part you don't want.
