## Description

Bring the bounce back to your backyard with Machrus Upper Bounce Heavy-Duty Premium Trampoline Springs. Over time, trampoline springs naturally wear out—becoming rusty, stretched, or weakened—which compromises both performance and safety. These replacement springs for trampoline restore the responsive bounce your family loves while ensuring every jump is safe and controlled. Each spring is crafted from high-quality galvanized steel, chosen for its exceptional resistance to rust and corrosion. Unlike standard springs that deteriorate quickly when exposed to rain, sun, and temperature changes, these heavy-duty springs are built to withstand all types of outdoor weather conditions. The cold-weather crack-resistant material maintains its elasticity even in extreme temperatures, giving you years of reliable performance. The innovative enhanced hook curvature design sets these springs apart. Each hook features increased curvature that grips the trampoline frame and mat more securely, preventing springs from detaching during active jumping. You and your children can jump with confidence, knowing every spring is holding firm. These trampoline parts are engineered for universal compatibility, fitting most standard trampoline brands on the market. Simply remove your old, worn springs and replace them with these premium-quality springs for an instant transformation in bounce quality and safety. The higher tensile strength delivers enhanced elasticity and a controlled, responsive jumping experience that makes every bounce more enjoyable.

Review: Heavy duty and strong - My sons trampoline started showing signs of stretched springs on one side. Found these and ordered a set. These are some nice springs that look to be of high quality and strength. They took some elbow grease to get them stretched back onto trampoline mat but once they were all on it looked good as new. Whats nice is that they offer various sizes for whatever tramp you have. Like with any metal over time they will eventually weather and may start to rust but these are so inexpensive, you can always change them as needed. I wouldn't hesitate to buy these again if needed.
Review: GREAT price and these worked so well! - WE have a My First Trampoline and had many broken springs. I changed them with these last spring and they are still going strong. Great cheap and easy fix for the trampoline. I did have to do some sewing and you need a heavy duty thread for that.

WE have a My First Trampoline and had many broken springs. I changed them with these last spring and they are still going strong. Great cheap and easy fix for the trampoline. I did have to do some sewing and you need a heavy duty thread for that.

### ⭐⭐⭐⭐⭐ 6.5" Trampoline springs
*by G***I on May 9, 2014*

The springs arrived quickly from Amazon and thank God I ordered the correct size. The originals were stretched out a half inch and there was no mention of the size in the booklet that came with the trampoline. The trampoline mat was replaced and I didn't know if the replacement was the same size as the original which helps determine what size springs to order. The trampoline is a 72 ring/spring and there were 15 in a package so I ordered 5 sets to replace the originals with 3 left over. So if you're replacing your mat, examine the springs and replace them if they're stretched out. I would recommend the Upper Bounce springs and would order these again when it's time. Make sure you purchase the Spring Pull tool for ease in attaching the springs to the frame...unless you already have one.
