Our take on the Heavy-Duty Garage Door Extension Springs Kit, 110 lb, 14.02 x 8.70 x 5.00 Inches

This is a two-spring extension kit for standard 7-foot garage doors, rated at 110 lb per pair. The springs are steel, sold with the usual extension-spring hardware, and are meant to replace worn or broken springs of the same lift rating. It suits a DIY owner replacing like-for-like springs on a single-car door; it is not a universal kit, and the rating must match your door's weight and track setup.

Pros
  • Steel construction built for daily open-and-close cycles
  • Rated 110 lb, a common match for single-car doors
  • Designed for 7-foot door systems
  • Pairs with standard extension-spring hardware
Cons
  • Unbranded, so no manufacturer spec sheet or support line

  • Extension springs store heavy tension and are risky to install without the right tools
  • No safety cables or detailed instructions confirmed in the kit

Questions and answers

Will this fit my garage door?
Only if your door is 7 feet tall and uses extension springs rated around 110 lb. Measure your door and check the old spring's rating before ordering.
Is 110 lb the rating for one spring or the pair?
Treat it as the lift rating for the set. Springs are matched to total door weight, so confirm how your existing pair is rated before swapping.
Can I install these myself?
Extension springs are under heavy tension and can cause serious injury if they slip. Many owners hire a technician; if you DIY, use proper winding bars, clamps and safety cables.
Do I need safety cables?
Yes. Safety cables run through each extension spring so a broken spring stays contained. Confirm whether cables are included and add them if not.
Will these work with my garage door opener?
The opener only lifts what the springs balance. If the springs match your door's weight, the opener works normally; mismatched springs make it strain.
Where is the Heavy-Duty Garage Door Extension Springs Kit, 110 lb, 14.02 x 8.70 x 5.00 Inches cheapest?
At Walmart, for $139.98, as of our latest check.
