Could you push up the dust cover and reshoot the photo? From the blue dust cover and the glimpse of the nut, I'm going to guess they're Bilstein inserts. But I can't say for sure without a better picture.
If they're not leaking, they're worth keeping, but they're likely old, so who knows?

Agreed, they look like they might be Bilsteins; if the shaft appears to be almost as wide as the housing, that'll pretty well seal it.
Very good, very durable, have had 'em on my 931 for a long time. Also run Bilsteins on my 924 racecar, but those are a rather different piece...

Im just debating what to put on temporarily until I can do the Rear springplate bushings and go full coilover on my 931.
Would these have been a factory piece or a later upgrade? As I have seen the Bilstein upgrade where you have to weld the threaded ring to the top of the strut housing, but these are clearly NOT that.

Well, not sure if it helps, but I'm planning on leaving these on my 931 when I lower it (maybe 1", hopefully this summer). I don't plant to go up substantially on spring rate, and the rest of the suspension is stock with (refreshed) rubber bushings etc.
Not sure what your end target is for performance; are you planning on more of a track suspension build, what kind of spring rates and bushings? At some point, yes these would not be ideal for higher spring rates... but I'd ask what you'd be intending to replace them with, and what the intended use of the car is... I would not say that Koni yellows would be an upgrade for these, not in track use, not based on my experience with same. Not for a full race suspension build... and I don't believe the Konis have the same durability as the Bilsteins...

Im going with poly bushes front and rear (poly bronze for spring plate) and 300F coil, 475 rear. This is a "back roads/canyon/mtn carver"
I already have a front coil conversion (with the stock spring cup cut off) with koni's already in them, ready to go on, but thats the easy part, so I wont do that until I can do the rear.
these bilstiens would just be place holders, as the current strut mounts are shot, and, what ever struts that are in it now are some cheap crap.

SO: until I install the coilovers set up (front and rear) im going with a temporary "stock" set up just to replace the crappy struts that the PO put in.
(and all the rest are for sale)
Now can the "Top collar" Bilsteins be swapped into the Coilover bodies? and would they work with the 300lbs springs?
