The 262 x 1.75″ x 37″ garage door torsion spring pair is an ultra-heavy-duty counterbalance set for extra-large residential doors, heavy insulated sectional doors and light-commercial overhead doors. Each spring is wound from oil-tempered spring wire with a 0.262″ wire diameter, a 1.75″ inside diameter and a 37″ coil length — a heavy-gauge, long-body combination that delivers considerably more lifting torque than standard single-car residential springs.
Specifications at a Glance
What You Receive: A Matched Left + Right Pair
A two-spring torsion system needs one spring of each hand. The springs mirror each other so both unwind in the correct direction as the door rises. This set includes one of each, so a full replacement needs nothing else ordered.
Left-Wound Spring
- Mounts on
- Right side of the shaft
- Winding cone
- Black (industry standard)
“Right side” means standing inside the garage, looking out at the door.
Right-Wound Spring
- Mounts on
- Left side of the shaft
- Winding cone
- Red (industry standard)
Cone colour indicates wind direction — not wire size. Those are separate colour codes.
Only replacing one side? Order the individual spring instead — right-side spring (left wound) or left-side spring (right wound), both 0.262″ × 1.75″ × 37″.
Will This Spring Fit My Door?
Torsion springs are not universal, and matching a single dimension is not enough. Work through this checklist before you order — a spring that is one wire size off will leave the door either unliftable or dangerously spring-heavy.
- Wire diameter measures 0.262″ critical
- Inside diameter measures 1.75″ critical
- Unwound coil length measures 37″ critical
- Your system uses two springs, one per side
- You know which spring is left-wound and which is right-wound
- Cable drums, torsion shaft and end bearing plates are in serviceable condition
- You have enough headroom and shaft length for a 37″ spring body plus cones
- Door height, width and actual weight are known

How to Measure a Garage Door Torsion Spring
Measure the wire diameter
With the spring fully unwound, push 20 coils tightly together and measure that length in inches. Divide by 20 for the wire diameter. Measuring 20 coils rather than one removes most of the error — and a 0.010″ mistake changes the torque significantly.
Example: 20 coils measuring 5.25″ ÷ 20 = 0.262″ wire.
Read the inside diameter
The inside diameter is normally stamped or cast into the stationary or winding cone — look for 1.75, 175 or P175. If the marking is unreadable, measure across the inside of the coil.
Measure the coil length
Measure the coil body only, excluding the cones, with the spring relaxed. If the spring is broken, slide the two halves together end to end and add the sections to get the original length.
Identify the wind direction
Look at the coil end nearest the winding cone. If the wire end points clockwise away from you it is one hand, counter-clockwise the other — or simply read the cone colour: black for left-wound, red for right-wound.

Safety Warning — Professional Installation Strongly Recommended
Garage door torsion springs store enough energy to cause severe injury or death. A 0.262″ heavy-gauge spring at full tension is especially unforgiving.
- Use correctly sized steel winding bars only (hex winding bars here). Never substitute screwdrivers, rebar, ratchet extensions or pliers.
- Disconnect the opener and secure the door fully closed before starting.
- Calculate the correct number of winding turns for your specific door — do not guess.
- Never stand directly in front of, or in line with, a spring under tension.
If you are not trained and equipped for torsion spring work, have a qualified garage door technician carry out the replacement.
Signs Your Torsion Springs Need Replacing
A 2–3″ gap in the coil means the spring has snapped.
A sharp report from the garage, often mistaken for a gunshot.
Hard or impossible to lift by hand with the opener released.
Door rises 6–8″, then the opener reverses or stalls.
Door closes faster than normal or drops the last stretch.
One side lags, or a cable has gone slack or jumped its drum.
These symptoms can also point to worn cables, drums, rollers or bearings. Inspect the whole counterbalance system rather than swapping springs alone — replacing a spring on a failed drum simply breaks the new spring.
Why Replace Both Springs Together
Paired torsion springs share the door’s weight and accumulate fatigue at the same rate. When one breaks, the other is typically at a similar point in its service life.
Fitting a single new spring alongside an old one leaves the pair mismatched: the new spring supplies full torque while the fatigued one falls short, so the door pulls unevenly, the cables load unequally, and the second spring usually fails within months — a second service call and a second set of labour. Replacing both at once restores even balance, keeps strain off the opener, cables, drums, rollers and hinges, and puts both springs on the same maintenance clock.
Compare Torsion Spring Sizes
Ordering the neighbouring wire size by mistake is a common error. Compare against the other pairs we stock:
| Size | Wire | ID | Length | Duty level |

Frequently Asked Questions
Does this set include both a left-wound and a right-wound spring?
Yes. The pair ships as one left-wound spring (black cone, mounts on the right side of the shaft) and one right-wound spring (red cone, mounts on the left side). That covers a complete two-spring replacement. If you only need one side, order the single right-side spring or the single left-side spring instead.
What does “262 x 1.75 x 37” actually mean?
Three measurements, in the order the industry quotes them: 0.262″ is the wire diameter, 1.75″ is the inside diameter of the coil, and 37″ is the length of the coil body with the spring unwound, excluding the cones. All three must match your existing spring.
How do I tell whether my spring is left-wound or right-wound?
The quickest check is the winding cone colour: black indicates a left-wound spring, red a right-wound spring. Otherwise, look at the coil end by the winding cone and note whether the wire end runs clockwise or counter-clockwise. Do not confuse cone colour with the wire-size colour code painted on the spring body — they are two different systems.
Can I fit this spring myself?
We strongly recommend a trained technician. Torsion springs hold enough stored energy to cause serious injury, and a 0.262″ heavy-gauge spring at working tension is at the demanding end of the scale. Correctly sized steel winding bars are mandatory; improvised tools are the most common cause of torsion spring injuries.
Will this spring fit a standard single-car garage door?
Usually not. The 0.262″ wire and 37″ body are built for extra-large residential, heavy insulated and light-commercial doors. Fitting a spring this strong to a light door leaves it spring-heavy — it will drift open, resist closing and stress the opener. Match the spring to your door’s calculated weight rather than assuming a heavier spring is better.
How do I measure a spring that has already broken?
Slide the two broken sections together end to end so the coils meet, then measure the combined coil body — that gives the original unwound length. Wire diameter still measures accurately on either fragment: compress 20 coils, measure, and divide by 20.
What else should I replace at the same time?
While the springs are off, inspect the centre bearing, end bearings, cable drums, lift cables and rollers. Bearings and cables are inexpensive relative to the labour of a second teardown, and a worn drum or frayed cable will shorten the life of a brand-new spring.
How is this pair shipped?
The set ships as a single package of roughly 30 lbs, approximately 41″ × 7″ × 4″. See our shipping policy for current dispatch times, carriers and rates.
Why Choose This Torsion Spring Pair
The 262 x 1.75″ x 37″ pair sits at the heavy end of the torsion spring range: a 0.262″ oil-tempered wire and a 37″ body give the torque that oversized, insulated, custom-timber and light-commercial doors demand, while the matched left-and-right set means one order completes the job. Precision winding keeps torque consistent across the cycle, so a correctly sized and properly tensioned pair returns the door to true balance — the door holds position anywhere in its travel, the opener does the small share of the work it was designed for, and every other part of the counterbalance system lasts longer.
Confirm all three measurements plus wind direction against your existing springs before ordering. Matching a single dimension, or choosing by door size alone, is not enough to guarantee fit. Contact us with your door specifications if you would like the size checked first.
