Rear Shock Assembly for 914-6 - Boge Options

[DennisV]

Rear Boges grey ? ...don't remember.
I don't remember ever seeing grey lower spring perches. Always black.

I am going off of what I bought from George at Auto Atlanta. Both front and rear were gray.

Perhaps worth noting, the front strut housing that came off our car was gray. Quite a bit darker when compared side by side with the color of the AA kit.

For anyone researching this in the future, I have put the NLA parts into the Parts Vault along with dimensions.

I think #4 is the only one outstanding as of this writing.

TL;DR
It doesn't appear #4 is needed as a separate part.

Long Boring Version
Because I obsess, I tried contacting more people on this part.

• PCNA Classic Restoration Atlanta: Contact a dealer
• Porsche Classic Restoration Dealer: We don't sell it, so we don't know anything about it.
• PAG Classic Restoration Stuttgart: No reply at all. No reply at all.

I went to High Performance House in Redwood City to get a 356 part, and took a print to show Rich. They have quite a bit of 914 stuff. He said I'm looking for something I don't need. That the "cap" was in fact part of the shock itself.

I had a dozen of the orange bump stops, but the foam rubber just disintegrated into a powder. It appears that the lifespan is just 25 years unless in a sealed bag. I believe the stepped side faced up so that the larger diameter would not pull through. They were yellow zinc plated parts.
The black bump stop was probably a replacement part when they realized the foam rubber disintegrated.
The bump stop you have will naturally move into the correct position over time so no need to force it.
Most of my parts are buried at this time, but if I can find the parts, then I will add to the thread. In the meantime, just seek an original assembly to take apart.

My rear bumpstops had disintegrated and I didn't want to wait a week so I ordered the *medium* hardness from Summit
Fit well!

Was trying to find a NOS rear jounce bumper to see if I could find one with the bonded washer in it. Honestly, I’ve never seen one with a bonded washer going back to the 80s when I was working on a lot more 914s than I do today. All I’ve ever seen is loose jounce bumpers and stepped washers that never looked to have been bonded to anything.

Here’s a couple pictures of a NOS part on eBay in Porsche bag and with Porsche part number from Brad Mayeur. Unfortunately no top end view.

Not saying Dave’s wrong, I was just trying to figure out what OEM really was since I’ve never seen a bonded jounce bumper in person.

Edit: In fact, it would seem @Davep is absolutely right!!

Thanks for teaching me about something I’ve never known about 914s!!! Brads listing states “No Longer Available. This is the correct, original bump stop that incorporates the “stepped” washer in the buffer. ” I guess there is exactly one available in 2024 (well now 2025 (IMG:style_emoticons/default/laugh.gif) )



Anyone else have a NOS part picture of the end view with the washer incorporated? Would love to get what it looks like documented before these parts just disappear.

Unfortunately Brad only has this one, otherwise I’d buy a pair of NOS just to see the end not shown in the photo. @ltd914. I’d love to have a set of NOS for my project but think any NOS parts ought to go to Dennis’ /6 restoration before I’d waste them on my /4 project.

Looks like there's still just the one.
A Pelican forum poster indicated he used VW units, modified, but didn't identify which VW unit nor how modified.

@artfrombama
Which one - red, blue, or plain?
