I've bought a set of new valve spring for a member but don't know which model they are. On the crane website they have 2 different one (one in a kit with titanium retainers) and another one alone... I got mine in a kit box (retainers and spring box) but I just have the springs so I can't compare with model number on the box. Since the spec between 2 sets are not the same anyway to know which one I got ?

thanks

What's the part number on the box, 903-2002 or 903-2003?

I found this info in a matter of minutes on Crane's website, I'm sure you could have done the same.

Mine is 2002.

Thanks , I dont know... i've check on their website and see that it has de 2002 kit and the part number for the other spring but never saw the other kit with 2003.

Thanks a lot! :)
