I have a Fox DHX 4.0 2010 with 222mm and it came with a spring 400x2.80.

But the spring it's to hard for me, so I wanted to buy a 300lbs spring but I can't find a 300x2.80 spring that fit's my shock.

Can I buy a 300x2.50 and it will fit my shock with no problems?? Or should I get another one???

Thanks and sorry for my poor english..

Fox labels their spring at maximum bind so a 2.8 is actually a 2.5/2.75. What is the stroke of your shock?

You need a 300x2.8, however, for some reason fox labels it as 300x3.24

I have a 222mm shock (E2E), and the spring that came with it is a 400x2.80.. (I think the stroke is 2.3 inch, but i'm not sure)

I was thinking og buying a spring from Fox 300x2.50 but don't know if it fits.. Or a Fox spring 300x3.24 it's the only springs available at the store..

You need to know the stroke of your shock. If your shock stroke is a 2.5 or less, then a 2.5 spring of another brand will fit. If it's larger than a 2.5 then you will need a larger spring stroke. The 3.24 will be fine so long as the free length fits (you will also have a weight penalty).

That's a 2.36 so you are good with the 2.5. That being said you mentioned your i2i is 222mm which means that much be a custom shock with that short of a stroke. You sure that's the correct shock size (222x60)?

Just got the srping 2.5...

And it fits.. but it fits in the limit! Is it dangerous to ride with spring in the limit.. The spring is not loose but is not also with any preload.. (and I can't turn in more preload..)

Post some pics but you should be fine. If you need more preload turn the spring at the same time as the preload collar.
