One Garage Door Spring Or Two

If you have very large heavy door then two or more springs will be required.

One garage door spring or two.

The cross section of the shaft is not circular one quarter of the shaft extends outward to form an edge. If your garage door has two springs pulling the door up then definitely have both replaced. The spring stays fastened inside the shaft by the stationary cone which matches the shape of the shaft. Typically using a single spring instead of two will save just two or three dollars.

Require only one spring. Many builders install one spring on garage door when they install the door. Garage door in many cases will dictate how many springs are needed for your garage door if the garage. Many garage door installers avoid using two torsion springs when they install a new door in order to save money at the time.

One spring systems utilize a larger spring that puts added stress on the other garage door system components. Doors with one spring place more pressure on the single spring than doors with two springs. Added pressure and stress on the center bracket or center bearing can cause premature failure. 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.

Why we use oil tempered torsion springs. 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. In most cases on double door 16 feet wide and larger we recommend replacing with a two spring system. 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.
