Description
The PanelDor Torsion Spring Kit is a made-to-order garage door counterbalance spring assembly manufactured to suit the specific requirements of your sectional garage door.
Rather than supplying a generic replacement spring, each torsion spring is configured according to the required spring specification, including wire diameter, internal diameter, spring length and wind direction.
Each spring is supplied as a complete assembled torsion spring with the appropriate winding cone and stationary cone fitted, ready for professional installation.
⚠️ Professional Installation Only
Garage door torsion springs operate under extreme tension and store a significant amount of mechanical energy.
Incorrect removal, installation, winding or adjustment can cause the sudden release of this energy and may result in serious injury or death.
PanelDor Torsion Spring Kits are intended for professional installation only. Repairs or replacement of garage door torsion springs should only be undertaken by a trained and experienced garage door professional using the correct tools and procedures.
Industry safety guidance similarly warns that garage door springs and associated components are under extreme tension and that repairs or adjustments should only be performed by trained door-system technicians.
🔩 Made to Suit Your Garage Door
Garage door torsion springs must be correctly matched to the weight and operating characteristics of the door.
Our PanelDor Torsion Spring Kits are manufactured to the required specification rather than relying on a one-size-fits-all replacement.
Depending on the application, the spring specification may vary by:
- Wire diameter
- Spring internal diameter
- Finished spring length
- Left-hand or right-hand wind
- Number of springs required
- Required lifting capacity
Correct spring selection is essential to achieving a properly balanced garage door and reducing unnecessary load on the garage door opener and other mechanical components.
⚙️ Complete Assembled Torsion Spring
Each torsion spring is supplied assembled with the appropriate spring cones installed.
A complete spring assembly includes:
- Torsion spring coil
- Correct winding cone
- Correct stationary cone
This provides a complete spring assembly ready to be installed onto the appropriate torsion shaft by a garage door professional.
📐 Available Spring Sizes
Our PanelDor torsion spring system supports a range of wire diameters and spring internal diameters to accommodate different sectional garage door sizes and weights.
Available spring specifications include:
- 5.72mm wire × 50.80mm ID
- 6.35mm wire × 50.80mm ID
- 6.35mm wire × 66.67mm ID
- 7.19mm wire × 66.67mm ID
- 7.19mm wire × 95.25mm ID
- 8.00mm wire × 95.25mm ID
The appropriate spring specification and finished spring length will depend on the individual garage door and counterbalance requirements.
↔️ Left-Hand & Right-Hand Springs
Torsion springs are manufactured with either a left-hand or right-hand wind.
The required wind direction depends on the position and configuration of the spring within the garage door counterbalance system.
For two-spring systems, the assembly will typically use opposing left-hand and right-hand wound springs.
The appropriate winding cone is fitted according to the wind direction of each spring.
⚖️ Correct Door Balance
The purpose of the torsion spring system is to counterbalance the weight of the garage door.
When correctly specified and adjusted, the spring system significantly reduces the force required to raise and lower the door, allowing the door to operate smoothly and reducing the load placed on the automatic garage door opener.
An incorrectly specified or adjusted spring can result in a door that is either too heavy or excessively counterbalanced.
This can affect the operation of the door and place unnecessary stress on components including:
- Garage door opener
- Torsion shaft
- Cable drums
- Lifting cables
- Hinges
- Rollers
- Bearings and brackets
Spring systems that are out of balance should be assessed and repaired by a trained technician.
🔄 Single & Multiple Spring Systems
PanelDor Torsion Spring Kits can be configured for both single and multiple spring garage door counterbalance systems.
Depending on the size and weight of the garage door, the counterbalance system may require:
- Single torsion spring
- Two torsion springs
- Multiple torsion springs for larger applications
Where practical, multiple spring configurations can provide a more balanced distribution of the required lifting force across the torsion shaft.
The number and specification of springs must be correctly calculated for the individual door.
🚪 Suitable for Sectional Garage Doors
The PanelDor Torsion Spring Kit is designed for sectional garage doors using an overhead torsion shaft counterbalance system.
Suitable applications include:
- Residential sectional garage doors
- Commercial sectional doors
- Custom sectional doors
- PanelDor garage doors
- Replacement torsion spring applications
- New garage door installations
- Single-spring systems
- Multiple-spring systems
The spring specification must always be selected according to the requirements of the individual garage door.
🛠️ Replacement Spring Applications
When replacing an existing torsion spring, the replacement should be correctly matched to the garage door rather than selected solely by the physical appearance of the existing spring.
Spring selection can be affected by factors including:
- Door height
- Door weight
- Cable drum type
- Lifting system
- Torsion shaft configuration
- Number of springs
- Spring wire diameter
- Spring internal diameter
- Finished spring length
- Required cycle life
If an existing spring has failed, the complete counterbalance system should be inspected by a garage door professional to confirm the correct replacement spring and identify any additional worn or damaged components.
Industry guidance notes that springs are among the most important and potentially dangerous components of a garage door and recommends professional inspection and replacement.

⚠️ Important Safety Disclaimer
Garage door torsion springs and associated counterbalance components operate under extreme tension and can store a significant amount of mechanical energy.
Incorrect handling, removal, installation, winding, unwinding or adjustment of a torsion spring can cause a sudden and uncontrolled release of this stored energy, potentially resulting in serious injury or death.
This product is supplied for professional installation only.
Only a trained and experienced garage door professional should attempt to install, remove, replace, repair, wind, unwind or adjust a garage door torsion spring.
Do not attempt DIY installation or replacement of this product.
Components connected to the torsion spring system may also remain under significant tension. These can include:
- Winding cones
- Stationary cones
- Torsion shafts
- Spring anchor brackets
- Cable drums
- Lifting cables
- Bottom brackets
- Associated fasteners and supports
These components should not be loosened, removed or adjusted without appropriate professional training and an understanding of the forces present within the garage door counterbalance system.
DASMA safety guidance specifically warns that springs, bottom brackets, cables and supports can be under extreme tension and that adjustments or repairs should only be made by a trained door-system technician using appropriate tools and instructions.
If a garage door has a broken spring, damaged cable or another counterbalance fault, do not continue operating the door. Arrange for the door to be inspected and repaired by a garage door professional.
⚠️ Please Note
PanelDor Torsion Spring Kits are made to the selected spring specification.
The torsion shaft, cable drums, lifting cables, centre bearing/bracket and other garage door hardware are not included unless specifically stated.
The correct spring specification must be confirmed before ordering.
If you are replacing an existing spring and are unsure of the required specification, we strongly recommend having the garage door assessed by a professional garage door technician before ordering.
Never attempt to compensate for an incorrectly specified spring by adding or removing spring tension beyond the requirements of the garage door system.
