How to choose
- Spring Length and Gauge. Measure your old spring's length and gauge to ensure compatibility. Using the wrong length can create an uneven bounce or require adapters. Thicker gauge (lower number) means stronger tension.
- Material and Coating. Galvanized steel offers the best rust resistance for outdoor trampolines. Zinc-plated options are cheaper but may corrode faster in humid climates. Consider a powder-coated finish for extra protection.
- Quantity Needed. Count the number of existing springs or check manufacturer specs. Kits typically include 72 to 96 springs, but you may need more for larger frames. Buy a full set to ensure even tension.
- Safety Features. Look for closed-coil ends or caps that reduce pinch risk. Springs with tighter coils are safer for kids. Always use a spring tool to avoid injury during installation.
- Brand Compatibility. Some brands like JumpSport and Acon make springs specific to their frames. Universal springs can work but may require adapters. Check product descriptions for fitment details.
Frequently asked questions
How often should I replace trampoline springs?
Springs should be replaced every 2 to 3 years for regular outdoor use, or sooner if you notice rust, loss of tension, or visible damage. Frequent use or harsh weather may shorten lifespan.
Can I mix different brands of springs on my trampoline?
It is not recommended because different springs may have slight variations in length, tension, or coil spacing, leading to an uneven bounce and potential safety issues. Always replace with a matching set.
What is the best way to install trampoline springs?
Use a spring puller tool to safely attach each spring. Start by hooking one end to the trampoline frame, then use the tool to stretch the spring and connect it to the jumping mat. Wear gloves to protect your hands.
Are premium springs worth the extra cost?
Premium springs made of heavy-gauge galvanized steel typically last longer and provide a better bounce, making them worthwhile for frequent use or safety-conscious families. Budget options can suffice for light, occasional use.
How do I know if my springs need replacing?
Signs include visible rust, corrosion, stretching, or a sagging jumping mat. If the bounce feels uneven or less responsive, or if you notice pinging noises during use, it's time to replace the springs.
Can I use shorter or longer springs on my trampoline?
Using different lengths can alter tension and bounce performance. Shorter springs create a softer bounce; longer ones offer more stiffness. Stick to the manufacturer's recommended length for optimal safety and performance.

For most owners, the JumpSport 350 springs provide the best balance of durability, safety, and bounce performance, making them our top overall pick.
