If your recliner won't lock in place or sags when you lean back, the tension spring is a common culprit. The 2 Pack 3-5/8 Inch Recliner Spring Replacement is a straightforward repair option for this kind of problem, but the key is matching the spring to your chair's mechanism.
Quick Verdict
This replacement spring set is priced at USD 18.99 and is designed for interchangeable recliner mechanisms, including Southern Motion, Catnapper, and Lazy Boy models. If those names match the mechanism in your chair, this is a strong candidate for the repair.
Who It Suits
This set works for anyone whose recliner uses a long-neck tension spring and who wants a second spring as a backup. Since the package contains two springs, you can replace one side and keep the other for a future repair. It is also suitable for smaller DIY uses beyond seating-sofas, automobiles, bicycles, toys, lighting fixtures, furniture, crafts, molds, hardware, and appliances.
What Stands Out
The spring's defined dimensions are the most useful detail. It has an overall length of 3-5/8 inches, a hook inner diameter of 3.46 inches, a coil body length of about 1-13/22 inches, and a 2mm wire diameter. The 45-degree hook deflection is also worth checking against your old spring. These specifics make it easier to decide before you order.
Meaningful Trade-Offs
Because the spring has a fixed overall length and hook deflection, it is not a universal part. You need to compare those details with the spring you are removing. If the measurements differ, this pack won't be the right match. The trade-off is that this is a precise replacement part rather than a flexible adapter.
Product Notes
2 Pack 3-5/8 Inch Recliner Spring Replacement

This set brings together the practical details: a long-neck design, a mechanism-assist/lock/tension spring, and compatibility with interchangeable mechanisms such as Southern Motion, Catnapper, and Lazy Boy recliners. Priced at USD 18.99, it is a reasonable way to get a matched pair for the repair. Choose this set if you need a long-neck recliner spring and the listed overall length lines up with your existing part. The main limitation is the same specificity-this is not a one-size-fits-all replacement, so the measurements need to align before you buy.
Bottom Line
The 2 Pack 3-5/8 Inch Recliner Spring Replacement is a practical fix for a recliner that matches the listed dimensions and mechanism type. If the measurements align, this set is a straightforward purchase.
