What is the life expectancy of the springs, and are they replaceable?

I have used my forearm crutches hard for almost five years, and springs work as well as the first day. I called Millennial Medical to ask if it was advisable to lubricate them, and they said it was not necessary. So I didn't! They work great, even after trudging through snow and mushy puddles.

Mine lasted about five years, but they went bad because I accidentally stepped on the wire and pulled really hard, if you take good care of them they should last at least ten years imo.

I am not sure what spring is in it but this is designed as a direct OEM replacement. I am at 17.5PSI with no issue whatsoever.

You can continue to use your old springs until they become stretched. The way you tell this is by taking one off of the trampoline and holding it in the air against the sun. If you can see sunlight through the coils then they are stretched and will need to be replaced soon.

The springs are kind of loose though meaning they expand more than others under weight. As far as a bounce, no. But if your attaching to a swing frame they will lickly be to long. I had to replace them only 6 months into use for the elliments in Okinawa rusted them away.

the spring "should" last for years. at least my older pair have. I had them for 20 years and the spring was still working though some wear was obvious. The point here is that the edges will wear out well before the spring and given how cheap they are just replace every few years anyway. :-)

I assume they can replaced as there are six screws to take the back off. I did not see any warranty information.

Seems they should last longer than a couple years. Where should or can this be Serviced???

I don't think so, 2 years ago we broke the spring on the left side and had to replace it, same as the spring on the right side, so I would think unless it breaks you shouldnt need to replace I\t

You may use your old springs, but if they were wore out then new ones would be helpful.

Yes, leaf springs must be changed in pairs. Over time the steel fatigues and the leaf springs flatten out. On a 10yr old pickup truck w/ 150k miles on it the old spring was nearly 1.5 inches shallower than the new one when laid directly upon it.

Only when they crumble or break down. Otherwise you should not replace them.

Nope ! Its not possible ! I have some little springs and holes just on the right side, where they fit. Maybe with new parts!

I would contact Hellwig to buy the right springs. That is what I did before ordering. 1-800-435-5944

the 6 replacement springs are free.(that is the quantity that is sent) But they charge 8 dollars for shipping and handling.

I think you'll be happy with them. For the money, they're a great upgrade. I can't say if they're better than the originals, since I can only compare them to the 30+ year old, beat springs I replaced. I've used progressive springs on a couple of bikes now, the other being my 1980 CB750c, and I'm really happy with them. They were perfect on the 750, which is good since it didn't have air shocks to compensate. For the money they seem to be the best springs out there.

I have yet to replace mine. As long as you wash, dry & power them they should last quite a while.
