I have an 83US A/T

Im installing Boge factory replacement shocks, but the new shocks do not have the adjusting collar, how do i adjust them? Do i twist the shafts in/out, or are they just pre-set at a certain height?

Thanx

The only adjustable feature on a Boge is ride height BUT that is the threaded sleeve and nut which you remove from your old shock and push on to the new shocks. Very early 928s did not have front adjustment but ALL have rear.

The new shocks i got do NOT have threaded adjustments for the adj nuts. Ie, they appear to be fixed. My question is are they truly fixed, or do i have to twist the shafts for adjustment?(Twisting them does appear to extend the rod, but i've no idea how far i'm supposed to twist them if that's the case).

I also just sent you a PM too.

Thanx for your help.

Here's a pic of the shock i pulled:



The new Boge shocks dont have the same threads on the body(or any threads, just little dimples to hold the coil holder in place).

Apparently the threaded collar is supposed to come off? I just dont see how those threads are removable. I don't even see a seam.
Also the new boge shocks have dimples where the threads appear to be on the one i pulled, so i dont even know how id get them on the same spot on the other shocks.

Help!

LOL...

That looks like a Bilstein shock that you have removed. Is the top anodized gold? If so, Boge's are not an upgrade......

m21sniper

They say Boge right on the side of the rubber bushing, and also have a Porsche part number on them. They're also oil filled(leaking), arent bilstiens all gas filled?

The part number is 928 343 055 06

The sleeve is still on your shock ( the thingy with the threads on it slides off) Don't mess up the threads getting it off!!!!!

m21sniper

I dont even see a seam. Yikes, this thing is going to be a BITCH to get off.

Well, i guess im back at it.

Wish me luck guys...and thanx for the help!

PS: I cant freakin believe these threads arent sold as part of a new set of shocks...

That is a Bilstein: all shocks are oil filled - gas pressurized is a feature to prevent cavitation in the internal valve body, so dead bilsteins can leak oil. The test for gas still present is to push the rod in - it will extend itself if the gas charge is still present.
If you have Boges, you need the threaded sleeves, appropriate adjuster nuts and spring perches as noted on the 'other' forum. Otherwise, trade in your Boges for replacement Bilsteins.

Also note that the perches are actually at slightly different locations on the Boge vs Koni. Fitting the Konis without changing the adjuster resulted in a drop in ride hight of nearly an inch!

OK Houston, i definitely have a problem



NO WAY these are the same shocks!

What EXACTLY do i need to convert back to Boges? I'm NOT paying 1000 bucks to replace 4 bilstiens- unless someone here is sponsoring me.

Ketchmi

Bilstein's can be rebuilt by the factory at a considerably less cost than replacement.

BTW, can you zoom in on where it says Boge on a Bilstein shock? If the threads are cut into the body as those appear to be, they are Bilsteins. You will need the bottom threaded sleeves and adjusters to put the Boge's back on.

m21sniper

Heh, they're definitely bilstiens that came out of my shark(no wonder the freakin thing handles so good, even with beat shocks!)

Just talked to the fine folks at 928 Specialists and they're gonna hook me up with a great price on replacement Bilstiens and take my Boges in trade.

No wonder they get the vast majority of my 928 business.

THANX to Wally, Jeannie and Co!
