Xray progressive springs
 

Xray progressive springs is there any way you can tell if you have them? Any markings/ paint?

All of the X-ray springs will have a numerical engraving on the end of the springs, progressive springs will have a range engraved.

Yes, the normal ones will have e.g. "2.5", "2.6", "2.7", etc. engraved, while the progressives will either have "2.3-2.6" or "2.5-2.8" on them (those two being the only progressives I've seen from Xray)

Thanks
