Need to High Cycle Your Torsion Springs? Use Calculator Below. Once You Are Satisfied With Your Measurement You May Select Your High Cycled Spring(s) >>>>>>>Here
Please note - Due to size and other factors of High Cycled Springs we are not able to return them if you measure Incorrectly. We can only return common sized Torsion Springs.
Increasing Torsion Spring Life: One of the most commonly asked questions to our sales staff is - how do I increase the life of my torsion springs? The answer is convert to a spring with a larger wire size and match the inch pounds per turn (IPPT) of the original spring. This will result in a spring that is capable of more maximum turns and therefore a higher cycle life than your original spring. Use the calculator above to choose your high cycle springs.
Don't see your specific Size, Length, or Inside Diameter? We carry Torsion Springs up to 7" Inside Diameter and .562 Wire Sizes in any length.
We offer most wire and Inside Diameter dimensions that are used in residential and commercial applications, from .164 to .467. Spring fittings or cones are available from 1.75, 2", 2-1/4", 2-5/8", 3-1/2", 3-3/4", 5-1/4", and 6" If you don't see the size you need just call us.
Please thoroughly read and understand all instructions before attempting any garage door repair. CAUTION: Garage door springs, cables, brackets, and other hardware attached to the springs are under very high tension and, if handled improperly, can cause serious injury or death. Do not attempt any repairs without the proper tools, instructions and safety equipment. If you have any doubts about your ability to perform the work safely, please contact a door professional to complete your repair.

Two very important numbers are necessary in calculating proper torsion spring conversions:
IPPT (Inch Pounds Per Turn)
Maximum turns
To convert a spring from one wire size or I.D. to another, you need to stay as close as possible to the original torsion spring’s IPPT, while making sure the new spring has at least as many maximum turns as the original torsion spring.
Constant = (A number developed from spring wire formulas that relates to a specific combination of wire size and I.D. Constant equals the number of active coils times IPPT.
(refer to constant charts to establish your IPPT)

For example, suppose you wish to replace the following torsion spring with a torsion spring with a higher cycle rate.
1 3/4” I.D. x .250 x 34” long
First determine the IPPT of this torsion spring.
Length + Wire Size = Total Coils
Total Coils – Unused Coils = Active Coils (subtract -5 for unused coils)
Constant divided by Active Coils = IPPT
Lets use the above formula to figure the IPPT of our example torsion spring.
34” + .250 = 136 Coils (1” divided by .250 = 4 coils per inch)
Refer to the (Constant Chart) above for the variable based on Wire Diameter and I.D.
Lets use the (MIP Chart) above to determine Maximum Turns.
MIP is 358 for our wire size of .250
Divide 358 by 43.8 (IPPT) which will = 8.2 Maximum Turns for this example.
Now that we know how to determine IPPT and Maximum Turns for our Torsion Springs, we can use this information to upgrade our torsion springs to Lifetime High Cycle Torsion Springs below.
