If your trampoline just isn't bouncing like it used to, these replacement springs from VONNST might be exactly what you need! Available in five different sizes ranging from about 5 to 7 inches (12cm to 17.8cm to be precise), these springs are made from heavy-duty galvanized steel that stands up to weather and constant use. The smart design features tapered coils that are wound extra tight, giving you better elasticity and stretch compared to ordinary springs. Each spring has two different hook ends - one is more curved to grip securely onto the trampoline mat clips, while the other is less curved to fit smoothly into the metal frame. Before you order, make sure to measure your existing springs from hook end to hook end to get the right size replacement. These are perfect for replacing springs that have stretched out over time or started rusting. A quick tip - using a spring pull tool will make installation way easier, especially if you're doing a full set replacement. The silver finish isn't just for looks either - it provides extra corrosion resistance. Whether you're maintaining a backyard trampoline or doing repairs at a playground, these replacement springs will restore that satisfying bounce and keep the fun going for years to come. Just remember that there might be a slight size variation (about 1-2cm) due to manual measurement, but that's normal for this type of product!
