05 Yukon XL - shock question

[mountie]

I had my Yukon SLT up on a lift today..... I changed the oil and lubed ....

Discovered my Hydro Booster is leaking - going to replace....

BUT.....

I saw my 4 shocks. They seem to work fine..... Rears are clean / no leaks.... They are all blue color......
I don't think that is a factory color? ( I saw a paper sticker at the lower part of shocks / worn out)

Rears are Nivomat ( style?) Considering the blue color......

Any idea what brand it could be? Or is blue OEM??

No shit..... Man-o-man..... I wonder if this set has lasted for the 145,000 miles???

They had a little bit of rust spots on the housings ( not serious rust, but showing age )

The Carfax on this truck is quite lengthy! Oil was changed no more than 4,500 miles each time from new,
All fluids changed/flushed a couple times.

I'm impressed with the previous owner!!

You got a good one! Mine are blue too and original and almost the same mileage. Nothing wrong with them either, still rides nice and tows perfect.
