How do you tell a rear Bilstein OEM from Bilstein Sport?

[Jean]

Shock is yellow and has blue Bilstein written on the bottom of it, what is most likely?

I do not see any B36 ..... marking on it? Did ALL bilstein sports have a B36 stampled on the body?

Bilstein says all yellow shocks are "sports", but I have seen yellow HDs, which their site does not mention, just sport and touring.

[Jean]

But there were non sport yellow bilsteins as well, oem ones ?

[Danny]

If its yellow you're good IIRC. I had factory bilsteins on one of my cars and they were black.

[Jean]

Alright, i'll pick these up tomorrow then to have as a spare.

You can call them with the number and they will look it up for you. I emailed them and they got back to me in a few days time.

[Jean]

Yeah, you beat me to it. I'll pick them up and call Bilstein on monday to confirm. Thanks!

[ColdAccord]

you can just google the number

My Euro car came with factory sports and they had a BMW roundel on them.

I also had factory bilsteins in my car and the were yellow...

Me too, and they said made in west germany near the eyeball on the bottom. And they were yellow

[Jean]

PN on them is 5090720h000, google does not find anything.

[JamesE30]

Same as above mine had a BMW roundel and made in west germany etched in them at the bottom

[Jean]

According to Bilstein the number engraved is a serial number, once I ship them over to get re-valved (need to decide if I want these done for a soft street rate springs or some crazy j-spec type rates lol as a 2nd set) they'll be able to figure out what they are.
