Torsion Spring vs Extension Spring | Which is Better for Your Garage Door?

: 20 March 2024

When it comes to garage door repairs or replacements, choosing the right type of spring is crucial for smooth operation and longevity.

Torsion and extension springs are the two primary options, each with unique characteristics and advantages. Understanding the differences between them can help you make an informed decision about which one is better suited for your needs.

What are Torsion Springs?

Torsion springs, positioned horizontally above the garage door, store energy as they twist when the door closes and then release it as the door opens. This setup ensures a smoother and more controlled operation compared to extension springs.

Notably, torsion springs boast superior durability and longevity over extension springs, making them a cost-effective option. Moreover, their parallel installation to the door tracks enhances safety by minimizing the risk of accidents or injuries.

What are Extension Springs?

Extension springs, positioned vertically on either side of the garage door, elongate and contract to aid the door's movement. Though simpler to install, they demand more upkeep than torsion springs. Despite being cost-effective, extension springs are vulnerable to wear and tear due to exposure, necessitating more frequent replacements.

Torsion Spring Vs Extension Spring

Feature	Torsion Spring	Extension Spring
Operation	Turns on a shaft	Expands and contracts
Extension	Partially extended	Fully extended
Durability	Sturdier, lasts longer (15,000-20,000 cycles)	Less sturdy, shorter lifespan (up to 10,000 cycles)
Motion	Controlled	Jerky
Adjustment	Less prone to needing adjustments	More prone to needing adjustments
Complexity	Less complex, fewer parts	More complex, more parts (sheaves, cables)
Maintenance	Easier to lubricate and maintain	More wear and tear on additional parts
Operator Wear	Less wear on the operator	More wear on the operator
Safety	Safer when it breaks (stays on the shaft)	More dangerous when it breaks (it can fly off)
Cost	More expensive	Less expensive

Which One is Better? — Torsion Spring Vs Extension Spring

While both types have their merits, torsion springs generally emerge as the victor due to their safety, durability, and quieter operation. However, there can be cases where extension springs make sense:

Tight budget: Extension springs offer a more affordable option if cost is a primary concern.
Limited headroom: Extension springs might be your only choice if space above the door is restricted.
DIY repairs: If you're comfortable with repairs, the simpler spring replacements of extension springs might appeal to you.
