A simple guide to matching your garage door weight with the right extension spring color code.

Extension springs help counterbalance the weight of your garage door so it can open and close smoothly. To choose the correct replacement, match the spring rating to the actual weight of your garage door and use the proper color code as a reference.

Installation Recommendations

Important: For most residential extension spring systems, springs should be replaced as a matching pair. Installing only one new spring can create uneven door balance, extra strain on the opener, and unsafe door movement.
  • Always replace both springs at the same time to maintain proper door balance.
  • Select the correct weight rating from the drop-down menu to match your garage door.
  • Follow your door manufacturer’s installation instructions and safety guidelines. Professional installation is recommended.

Before Ordering, Check These 3 Things

#1

Door Weight

Select the spring rating that matches your garage door weight. The listed rating is intended for a standard two-spring setup, with one spring installed on each side of the door.

#2

Spring Color

Use the color on your current spring as a helpful reference, but do not rely on color alone.

#3

Door Height & Setup

Confirm that your door size and spring system match the replacement spring you are selecting.

Safety note: Garage door springs are under tension. Follow your garage door manufacturer’s instructions and safety guidelines. If you are not experienced with garage door spring replacement, professional installation is strongly recommended.
