Restore smooth, balanced door operation with a pair of 25” x 42” extension springs designed for 7-foot-high garage doors. These springs help counterbalance the door for easier lifting and more controlled closing by reducing strain on the lifting system. This set features double ends with S-hooks, making it a great fit for standard extension-spring setups connecting between the rear hanger/stationary bracket and the pulley + safety-cable assembly.

Available in multiple lift ratings for door weights from 40 lb to 200 lb—select the correct option from the dropdown for proper balance.
