Go to this page of the RCS site. Look at the chart and tell me what measurement they use for spring rate. Unless I'm blind it says lbs/in. Explain to me what that might mean.

pounds per square inch would be a measuer of pressure

lbs per in is the relation between force applied and movement of a spring
usually shown on a graph

If the line is straight with a constant slope the sping is linear (500lbs per in)
if that line is a curve getting steeper towards the end then it is progressive, (This would follow an arc and require an equation to solve at a specific location along its travel)

in context it works - like you have already said dude - that means it takes for example 400lbs to compress the spring 1 inch.

e.g 'oh look at that spring its a 400 pounds per inch spring'

but if you simply say 'whats pounds per inch?' it makes no sense. for there is no numerical value for it to relate to.

Huckoveraduck, please concede defeat. This thread should close with a clear answer. I think it was supplied, as lbs/in is a valid measure for spring rate.

you cant come in at the end and say some crap that nobody cares about anymore.
thanks for your input - but take a hike!

Actually I care about it, that's why I posted. I am interested in a Ti spring, so I scrolled to the end of the thread where I found...no clear answer!

I'm glad people debate, as that will lead to better discussion, but you (Huckoveraduck) actually posted at the end to get a last quip in. Sorry to be an ass, but these forums can be a lot better.

Thanks guys that was a good and funny debate although it didnt help much.

Anyway besides all the pounds per inch s*it, one thing u agree on is that ti springs give better performance.

Next time u get a chance talk to RMR we all know he knows his s*it and maybe he can settle it.

By the way he agrees that ti springs have no performance differences to a steel spring, just weight.

I have a fox 2.8 x 500 spring on my Faith. Will an obtainium ti spring 400 x 3 be alright? I think it should be fine...and by the way I'm 150lbs.

Thanks

THis is when you ask for free length measurement. I can double check, but Im 99% sure the RCS and Obtainium ones fit a DHX. Double check though
