Heavy-Duty 100 Lb Garage Door Extension Spring – 2-Pack (Stretch Springs, 18,000 Cycles, Anti-Rust Coating)

About This Product

If your garage door is getting sluggish, noisy, or just not balancing right, the springs are usually the culprit.

This heavy-duty 2-pack of 100 lb extension springs gives you a solid replacement that'll get your door working smoothly again.

They’re made from heat-treated spring steel with an anti-rust coating, so they hold up longer than those cheap, bare-metal ones.

Each spring has a weight capacity of 100 pounds and is rated for 18,000 open-close cycles.

That’s a lot of use—way better than most basic springs.
The coil-to-coil length is 25.

6 inches, and the initial tension is 31 pounds, which is pretty standard for residential doors in this weight class.

We only sell them in pairs for a good reason—mixing an old spring with a new one throws off the balance and can cause uneven wear or even safety issues.
Replacing both at once is the right way to do it, and you save money buying them together anyway.

Make sure to weigh your door if you're not sure about the weight—don’t guess.

These are for 100-pound doors using an extension spring system.
If that matches your setup, this set gives you reliable, long-lasting performance.
Good quality, good price, and you’re back to a properly functioning door in no time.
