All Pro Offroad shock part# confusion

I'm looking at the 10" shocks on here for my truck, but when I google the part numbers, the shocks come up as 5100's and not 5125's. I'm confused now. Is part number 33-185552 a 5100 shock or is it a 5125 shock?

Thanks for the quick response, Zach. I've read that thread a few times. It doesn't exactly answer my question, though.

I did a little more googling and came to the conclusion that those shocks used to be 5125's but are now considered 5100's?? There's an old part number for them that used to come up at 5125, but the new part number is a 5100...still confusing lol

I guess it doesn't really matter, though. There is no difference between 5100 and 5125 according to all the google searches and articles I read.
