Installing progresssive springs

Postby Garacane » Wed Aug 28, 2013 7:47 pm



Ok guys, dumb question of the day. I've had my front end tore apart for a little while now and I'm finally getting it back together. I have progressive shocks and I can't remember which end goes in first. They go from a normal coil to a tighter coil. I tried to find some info in the forum but I didn't really find what I need to know. Any help would be great. Thanks.

I was in this position a couple of months ago. Previously heard tighter wound end goes down, but the Progressive instructions said it doesn't really matter. Put mine in with the tightly wound end down and no problems.

Thank you for the reply. I'll install them tight side down.

I can't see why it would make any difference, but I actually installed mine the other way round (Tight wound end at top). A spring just gets compressed, so why would it matter if the tight wound end was at the top or the bottom? I put them both in the same direction as it seemed neater (Guess I must be moderately OCD!!), but couldn't find anything in the instructions stating which way round they go,m and that just convinced me even more that it didn't matter!! If someone can explain why it DOES make a difference, I would like to hear it.

This was interesting, so I went and looked in a Progressive Springs box and found the instructions. According to Progressive, if you put the tight coils down, you may get less spring noise, but functionally, it makes no difference.

From the horses mouth.... :lol:

Technically, the tighter wound end weighs a bit more, so putting that end down at the bottom gives you more unsprung weight than if it was at the top, which means a slightly less compliant suspension when going over bumps. But on our bikes I doubt you would be able to notice the difference.

On my 1500, I put the tighter wound ends at the bottom.
