• Complete Set – Ready for Installation: Includes 1 pair of 170 lb-rated garage door extension springs (25" relaxed length, 71" stretched length), 7ft tall. made from heat-treated spring steel for exceptional strength and durability. Also comes with 1 pair of non-slip safety gloves and step-by-step installation instructions—everything you need to get started right out of the box.
• Double Loop Ends for Superior Strength: Samson springs feature double looped ends, offering enhanced durability compared to open loops. With two coils connecting to the eye-bolt and pulley, they provide a more secure and long-lasting attachment. We exclusively offer double loop ends because they are the most reliable replacement option—and can safely replace any end type.
• Packing Included: Each package contains one pair of heavy-duty garage door extension springs rated for 170 lbs. Built for balanced, reliable performance with double loop ends for added strength. Perfect replacement for worn or broken springs to restore smooth door operation.
• Benefit: Replacing both springs with this heavy-duty pair ensures smooth, balanced garage door operation, preventing uneven wear, door misalignment, and damage to your opener. Durable heat-treated steel springs provide long-lasting performance and enhanced safety for your home.
• Importants: Replace Springs in Pairs for Safety & Performance – For best results, always replace both extension springs together. If one spring has broken, the other is likely near the end of its life too. Using a new spring with an old one can create uneven tension, causing the door to open/close unevenly. This can damage the garage door, opener, or cause rollers to come off track—posing a safety risk. Avoid costly repairs and ensure smooth operation by replacing both springs at once.
