Just making sure here....but you are talking about the rear shock or the front? I'd assume the rear?
If so, well here's some info to help you out. The shock eye to eye length is 6.50 and the stroke length is 1.50.
The DS needs a little heavier spring that some other bikes....the leverage ratio is a bit higher on it. Sorry I'm not good enough to give you a spring weight for him right off the top of my head.
If he's got the cash go for a 5th element....nice shock...for some it can be tough to tune properly.
If not....check out Fox...nothing to special...just dependable.
I don't know if any of the other companies make anything to fit that application...I bet they do..I just don't know myself.
Oh there's Romic too....they have all different sizes to fit a ton of bikes.
