Machrus Upper Bounce Premium Trampoline Springs Replacement 3.5-9 Inch, Heavy-Duty Galvanized Steel with Pull T Hook Tool for Installation, Set of 15

There were very good and strong but the trampoline material broke down after a year of used.will buy again.

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.

Exactly what we needed

So far so good. Good quality and easy to install. My daughter noticed a difference even after only replacing 1/2 of the 72 needed. I wish they weren't so expensive, otherwise I would replace all of them. Just pulled out the stretched ones.

Replaced a few broken or distressed springs and the tool worked well too fix them. Better than buying a new trampoline! When purchasing measure the entire spring, not just the coil part. I ordered the wrong size the first time.

I have owned five trampolines over the past 18 years. I always take them apart in the fall and reassemble them in the spring time every year. I have repaired mats and replaced broken springs, so I consider myself pretty familiar with normal wear and tear. I purchased these springs only five months ago, and already half of them have broke. I can tell which springs are the new ones, because they are a different color than the originals. In my experience, trampoline Springs fail in three different ways. First way is that a random spring will stretch out and need to be replaced. I have seen this happen a couple of times. honestly, it’s pretty remarkable that it doesn’t happen more often. I have kids who love to bounce, and I am not exaggerating when I say that after probably 1 million bounces (no exaggeration) I have only had to replace half a dozen springs for this reason. The second reason, is it a spring break in the middle of the coiled section. Again, this has happened maybe half a dozen times over the last 18 years across hundreds of springs. Again, I’m surprised it doesn’t happen more often. The third place that is spring can fail is just beyond the coil section where the metal is Benetta 90° ankle to become the hook that attaches either to the mat or to the frame. This is a natural weak spot, and is the most common place where springs seem to break Of these three locations, the most common place for a spring to break is in this third location. The average life of a spring seems to be about three years. That doesn’t mean that every spring breaks in three years, but I start noticing that spring will break occasionally after this time. So long is the trampoline is still good, I buy new springs, and they seem to be just fine, usually. I purchased these springs five months ago, and half of them have already broken. All of them broken the same spot. All them broke just beyond the coil, where the spring makes it right an angle bend. Although these springs worked fine until they broke, I seem to be replacing one every week now. Maybe it is just the particular lot that I received, and that’s totally possible, but it is just not the quality that I have purchased in the past. Perhaps the company, recognizing this, can send me some new springs, but in the meantime, I’m going to buy springs from a different company. As you are buying springs, consider my feedback when you are deciding between options. I will update this posting if the company has any feedback for me or replace the defective springs. Springs are a little like other underappreciated components that either get a one star or a five star review. If they work like they’re supposed to, they get five stars. If they don’t, they get one star. When you buy a trampoline spray, you just expect it to work and last for a while. Nobody expects them to last forever, and when you think about it, they take an incredible beating, but just keep doing what they’re supposed to in most cases maybe I should give this two or three stars and lower my expectations, but my experience with springs is that they are typically much more durable than these have been for me. Happy bouncing!

Figured I’d leave a review now that I’ve had these for an entire season. I installed these in April of 2021 to replace a few bad and stretched out springs on our trampoline and they have held up really well. I just took them off yesterday (12-2-2021) for the winter season and none of them had any rust and were all still very tight and springy after moderate use all spring, summer, and fall. Very happy with these and plan on purchasing another pack of them next spring to replace a few more of the old springs now that I know these are a quality product that will last.

Update several of the springs have snapped as other reviews have stated they don’t seem to be holding up well this brand. This may be the last time I order the springs they don’t seem to hold up well and we’ve had 3 or 4 that have just broken as others have stated in their reviews. So in the box some of the springs are faulty I had a whole box only a few of them in the box are faulty it’s hard to tell which ones are faulty not strong but weak or will fail. This is our second box. These are the originals that the trampoline had. Each time we buy a box there are only 2 or 3 of them are faulty. The rest to work fine. After a while the kids bounce to hard on the trampoline some of the springs bent once some of them bent it causes other to bend easier but we found this on Amazon and the box was enough to replace the bad springs with a couple left over. These were the exact spring 6 inch needed for the replacement springs that were bent on the trampoline these works fine.
