Garage Door Parts

Having a properly functioning garage door often depends on knowing and understanding the door’s mechanisms and the necessary parts that keep it in working order. After all, there are multiple garage door parts that are key for operation. If something is not working, it is important to know where to purchase replacement parts. Below, we have listed just a few important garage door parts and where to find them.

Common Garage Door Parts

Torsion Springs

Garage doors are very heavy but, with the aid of a torsion spring, are easy for you or the garage door opener to open. Unfortunately, when your garage door is not opening, the springs are often the first culprit. Garage door springs can wear down or break over time and create very dangerous environments if they do, so keeping an eye on their wear is important. Springs come in a variety of sizes and tensions, so it is important to replace your garage door spring with the existing size. Torsion springs can easily be found at any large home improvement store, such as Home Depot or Lowes, or can be purchased online. Don’t replace or repair garage door springs yourself. Even brief research will tell you that springs are under heavy amounts of tension, which means you only experts should handle them. 

Extension Springs

Extension springs assist in the operation of your garage door by counterbalancing its weight. These springs, usually installed above the horizontal tracks on both sides of the door, work by stretching and contracting to lift and lower the door smoothly. As the door closes, the extension springs extend or stretch, storing potential energy. When you open the door, this stored energy is released, helping to support the weight and ease the lifting motion.

Just like torsion springs, extension springs act as vital components that balance the door’s weight. They make it manageable to open manually or by an opener. They work in tandem with other parts of the garage door system, ensuring controlled and safe movement while preventing the door from slamming shut due to its weight. Regular spring and door inspections are crucial for ensuring door safety.

Weather Stripping

Having a tight seal at the bottom of your garage door is key to keeping pests out and keeping conditioned air in. The tight seal will help make your garage doors more efficient in the summer months, too. Over time, the seal on the garage door will begin to degrade due to use and being exposed to the elements. It’s a good idea to replace the weather stripping fairly regularly when you notice it is starting to break down. Weather stripping can easily be found at any store or order online from Amazon.


Periodically, the hinges that connect each panel of the garage door start to wear out and will need replaced. This will ensure that your door lifts smoothly each time. There are various sizes for hinges, so it is always best to make sure you know what size you need to replace. Hinges can be found at Home Depot or Lowes, but for more specific sizes you may have to search at a specialty store. Try looking online at Amazon or American Door Supply for just the right size.


The rollers on the garage door ensure that the door moves smoothly and freely along the garage door tracks. Sometimes rollers will need replaced, especially if they become corroded. Try online stores or big home improvement stores like Home Depot or Lowes for replacement garage door rollers.

Garage Door Lubricant

Lubricant may not be a garage door part but it’s an important thing to keep on hand. Having and using the right garage door lubricant is an essential part of maintaining your moving parts. It helps reduce friction between moving components, preventing wear and tear while extending the door’s lifespan. Look for a silicone-based or lithium-based lubricant. They offer superior performance and durability. These lubricants resist dust and dirt accumulation. Avoid using greases or oils, as they can attract debris and cause buildup, leading to operational issues. Regular application of the recommended lubricant to hinges, rollers, tracks, and springs helps ensure your garage door operates smoothly for years to come. You can find suitable overhead door lubricant at your local hardware store.
