## Description

Trampoline missing the good bounce?? Bring back the fun and jumping joy by replacing your deformed and/or missing trampoline Springs with these "Upper Bounce" Heavy-duty galvanized springs which are especially designed to increase bounce!

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.

### ⭐⭐⭐⭐⭐ 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.
