Just purchased cert/preowned Taco...What bilsteins are these?

Like the title says. I think these are 5100s but not positive. Tried looking up the numbers on google but no luck. I'm hoping they are in fact 5100s so I can get OME 885 and AAL in back and save myself some money.


This is how the truck sits now, I'm assuming whoever had it before me kept the stock shocks on it.

This is my first truck and real life changer for me and am excited to get off-road and get going places. Thanks for any help you might have

 

5100s

 

Make sure the front shocks are the same silver body...

 

Yeah fronts are the same look, I have pictures of them as well but they were shittier quality pictures so I didn't post. Thanks for the help!
