They say prgressive on them and are coil-overs. the only other markings on them are a string of numbers 1370 90-130. No 412 or 440 or any of the other common referrences. Oh, and they're black if that makes any difference.
RE: How can I tell which Progressive shocks I have?
Yes I have. Some look close but none match exactly. The bike is an '05 and I'll assume the shocks were put on some time near new. I figure minor cosmetic changes are normal from year-to-year. I still really can't say which ones they are for sure.

the numbers you gave are the springs, if I remember correctly these are the standard springs not the heavy duty ones. the 412 requires a tool to adjust them the 440 are adjusted using your hand
