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

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.

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.

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.

We were given an old trampoline by our neighbor. It is old, but the price is right. So I decided to do some basic improvements to it so my kids could jump on it safely. In total, I spent $180 and it bounces well now and is safe. The price of these springs was good. They were delivered quickly and in great condition. I ordered 60 new springs for a 96 spring trampoline. There were probably 10 springs that were totally sprung, loose, and just hanging on serving no function. I suspect there were roughly 30 springs that were visibly sprung to some degree such that when you removed them, you could compress them slightly (new springs are tight and you cannot see daylight beween the coils). After going around the trampoline and replacing all of those that fit the above categories, I had about 20 new springs left. So the kids and I went around the mat replacing any springs we didn't like or 1/2 of the springs in areas where all of the springs were old ones. SO our trampoline has 60 Shiny new springs and 36 old dull ones that appear to be in good shape. My kids said the difference was very noticable when getting back onto the mat. I wonder if I shouldn't have gotten 45 more springs and just replaced all of them. I think just replacing the bad ones was sufficient.

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.

I've decided all springs are crap. I have tried every brand I can find and they all break. I've bought these several times now because they're cheap and even the expensive ones break immediately. However, this is the second time I've received a rusted spring from this seller. I usually need the springs RIGHT NOW, so returning the entire box and waiting for a replacement isn't ideal. I wish they could just send me one replacement spring. At least this time it is only one out of 15 that's rusted. Last time it was too many.

Works as they should.

Unlike the replacements I ordered last year, 95% of these springs lasted an entire summer, while still managing to retain their elasticity. I also used some thicker, heavier springs from an old trampoline to fill in for the ones I didn't replace. I was worried they would overpower these and stretch them out, but they didn't. I wonder how they'll hold up after two years of service. Definitely worth the money.

Muy buenos resortes y resistentes

le ho prese come ricambio per tappeto elastico sono come le originali sono arrivate prestissimo

Works perfectly for the trampoline

funciona perfectamente.

Los resortes de buena calidad. Me hubieran gustado un poco más cortos pero al final funcionaron bien para poner a una hamaca
