ASKED QUESTIONS
Q: Should both springs
be replaced if only one
is broken?
A: Yes. If one spring broke, the other will likely
break soon. The amount of work to replace two springs
at the same time is a lot less than changing them out
at different times.
Q: How important is it to be
accurate when determining
your replacement spring?
A: It is very important to be accurate. A garage
door torsion spring system requires specific spring(s)
based on the height and weight of the door. When the
door is in the up position, it is important that the spring
still has a couple of winds remaining. This ensures that
the cables still have a small amount of tension, thus
keeping them from falling off the drums. Plus, if your
spring is too strong or too weak, it will be very hard to
raise and lower the door.
Q: The door has only one
torsion spring mounted.
What lifts the other side
of the door?
A: The energy from winding the spring is transferred
to the torsion tube, which disperses equal lifting power
to both sides.
Q: Do both springs on the
right and left need to be
the same?
A: Extension spring systems do need to have the
same springs on both sides of the door, but this may
not be the case for torsion springs. See the expanded
explanation about torsion springs on this page
(“IMPORTANT NOTE: Left and Right Torsion Springs
May Not Match”).

Torsion and Standard Torsion
systems use a torsion tube that disperses
equal lifting power to both sides evenly. The
energy from the wound spring(s) is combined
and transferred to the torsion tube. The torsion
tube, however, doesn’t know the length of the
left or right springs, or if there are one or two
springs (nor does it need to). It responds only
to the amount of energy applied to the tube
that, in turn, lifts both sides equally.
Many different combinations of springs are
needed for the exact height and weight of
every possible door. Therefore,
it is only a
coincidence if both sides have matching
springs; it is more likely that they wouldn’t
match. Some doors may have only one spring.
