Aoneky 220LB Heavy Bag Spring - Professional Punching Bag Shock Absorber for Boxing MMA Training, Reduces Noise & Vibration, Fits 75-220LB Bags, Top/Bottom Mount (4.6 inch)

Good fit, weight capacity appropriate, length correct. Would have been a bit easier to use if the hooks on ends were 90 degrees from each other.

Using this for a 100lb bag. It's bigger than I expected but holding up well after a couple of week of using it.

The bag glides nice with it. It is substantially wider and shorter than another bag spring I have, which raises the bag up higher than other bag springs. This is a plus in my book.

At under 5” this is the only spring that would work for my heavy MMA bag so it won’t drag on the floor. Reduces noise nicely.

It will hold a heavy punching bag over 100lbs. I would not recommend it for anything under 100lbs because you want the spring to flex. Anything under 100lbs, using this spring would be like using a solid piece of metal.

Snapped in less than a month of use. I have snapped most of the springs available for heavy bags that they sell on Amazon now, but this one lasted the least amount of time of any of the springs I've bought. Not durable.

It’s ok.

Works great, hung an everlast 100lb bag and it didn’t stretch much at all.I can tell my bag stand doesn’t creak as muchGood purchase, cheaper than the name brand stuff
