No it's both in a kind of sort a way,running the bike in 5.5 inch mode will give you a lower leverage ratio meaning you will need a slightly softer spring,running it in the 6.6 setting will give you a higher leverage ratio meaning you will need a stiffer spring.

That link for the dhx 3.0 is the kinda shock you want but not at that price.

It could but most were 50mm stroke,email the dude ask.

A 57mm stroke could fit but you would need to take the spring of and bottom the suspension to see if there is any clearance issues.

Not a lot more than it is now to be honest,120 max.

This ain't the right size but it will give you an idea.

A factor to consider, if you decide to buy a coilover shock: you may have to buy another spring if the one that comes with the shock is too light or too heavy.

The spring is used to determine sag on the rear suspension. This is pretty important - not enough sag, and the suspension will be too stiff. Too much sag, and you will use up most of the suspension travel just sitting on the bike.

I can only speak from personal experience, regarding the crappy factory shock that came on of my early FS bikes. If memory serves correctly, it had an 800 lb spring, and the ride was horrible. I tried out the same bike with a 600 lb spring, and the difference was night and day.

I think you can get different springs for a pretty good price these days, as long as you aren't looking for a titanium. You may need a bike shop to install it - other people here will have more expertise on that subject than I do. Any new spring you buy will have to be the proper length and weight.

One last thing - don't buy a spring that is too light and then crank the preload adjustment too much. It will affect the amount of usable stroke on the shock, and subsequently the amount of suspension travel you get. Fox, for example, used to say only three full rotations of the preload adjustment to set the sag. Any more, and a heavier spring was needed.

Not sure if all of that was helpful, or confusing, but at least you've got more info to help you make a decision.
