No doubt a stupid question..
I have a steel 600 x 2.35 on now. Thought i would keep my eyes peeled for a Ti one. Do just buy the same?

Are Ti springs rated the same as steel?

Try giving Loco a shout, he's got ti springs at reasonable prices in stock.

yup if they are rated the same they will give the same response. The rating is the spring rate which in this case I assume is 600 lbs per inch, which means that it needs 600lbs to make it compress by 1 inch. Although as the units arent give it could be any mass/distance, I would be surprised if they mixed units though..

2.35" is not an unusual size but it's not that common either. If you were holding out for second hand, you might wait a while before one came up.
Typically if you have an unusual ahem, stroke lenght, then suppliers will say just use one size up as it won't compromise the suspension. So for example, rather than get a 2.35" stroke spring, you just use a 2.5" spring, which are more common.
The only downside to doing this is that you end up carrying more spring than you technically need. Just to explain that, the 600 lb/inch is the weight of the spring, as Toys19 says, it's the amount of force needed to compress the spring one inch. That's amount of force will be the same for any spring regardless of the other dimensions.
The stroke length is the overall length that the spring can be compressed by before the coils in the spring bind together. So if your damper has a stroke length of 2.35" and you run a 2.5" or even a 2.75" spring, then that spring will be marginally longer and therefore marginally heavier than it needs to be.
That can make a big difference if say you end up with a 2.75" length spring that is 20% heavier than it needs to be and therefore may end up being only marginally lighter than the correct length steel spring. And since weight is the only benefit from a Ti spring (really) it makes the exercise a bit pointless.

Quality info thankyou.
I ride a Hemlock and use this with the 6" rocker. Ithe air shock had a 50mm stroke, a57mm stroke would have been too long and would have caused bits to clash.
So presumably I should keep my eye out for 600 x 2.25 if they are more popular?

You don't get 2.35 stroke shocks. Its just what Fox mark on their 2.0" or 2.25" stroke shock springs.
600x2.25" will be grand. Not so much of a weight saving on the shorter springs though. Which shock is it?

It's a Van R and thanks. It's no wonder it's clear as mud if they write something different on it!

Manu tolerances on Ti springs can be lees than equivalent Steel springs though, I've seen manu's quote +/- 10% in some cases which can make over 50lb difference in higher rated springs.
There are some cheap Ti springs on the market and they are cheap for a reason if you get my drift and I would recommend you don't buy one as I and numerous other people have had problems with them in the past, (the one I had broke!!).
If you want a quality Ti spring with good tolernaces then you won't get much change from £200 and the best, (Obtainium), are near £250 but are like rocking horse sh1t to get hold of!!

Which spring did you break, 100mph?
EDIT: The manufacture of Ti springs is similar to the manufacture of Taiwanese frames in that there are only a few manufacturers producing for an number of brands.
