One Garage Door Spring Or Two

If your garage door has two springs pulling the door up then definitely have both replaced.

One garage door spring or two.

In most cases on double door 16 feet wide and larger we recommend replacing with a two spring system. If your garage door was originally set up with only one torsion spring then you are perfectly fine with having only one spring put back on the door. Typically using a single spring instead of two will save just two or three dollars. The spring stays fastened inside the shaft by the stationary cone which matches the shape of the shaft.

Require only one spring. If the garage door is in the open position and starts coming down and one of the two torsion springs break in mid travel there is usually enough power in the other torsion spring for the garage door opener to either bring the garage door back up or let it down slowly. Many builders install one spring on garage door when they install the door. Added pressure and stress on the center bracket or center bearing can cause premature failure.

Doors with one spring place more pressure on the single spring than doors with two springs. The garage door has one or two springs nested inside of the shaft. Many garage door installers avoid using two torsion springs when they install a new door in order to save money at the time. Some builders use only one spring when they install garage doors to save money but it may not be the best option for your particular door system.

The cross section of the shaft is not circular one quarter of the shaft extends outward to form an edge. The second spring will break it s just a matter of time which is usually within 6 months.
