KONI and rebuild service and Gas Charging

[scenario]

If we opt to have our Koni's rebuilt it is my understanding that they will no longer be "gas charged". Does that affect the unit in any way? If not then what is the point that they are originally billed as "gas filled/charged"?

That is some interesting info, not sure why the change. Is that because they are replacing the inner workings on the Koni's to a 'gas-less' design? I would hope Koni would be able to give you details on why the change and what is happening inside for the rebuild.

Here is the response. I actually had known about them not being "gad charged" after rebuild but never gave it any thought bc I was not getting them rebuiut years ago.

This is from Performance shock who rebuilds authorized for Koni. I heard Koni would rather not do rebuilding and suggests a few of these authorized places to have the work performed...

"Thank you for your email.
These will not be charged post service. As these are twin tube design there will be no change in function nor performance of dampers.
Service fee begins at $250.00 per unit pending inspection of internals. If upon inspection we do find any parts damaged or witnessing excessive wear then cost of replacement parts will be additional to service fee. We can provide an accurate quote once we have them cleaned, disassembled and evaluated. We do provide restoration services as well for an additional fee pending chosen options, blast/paint/decals, etc.

Please advise if you have any further questions or concerns.

Thank you and regards,

IIRC, the gas charging is primarily to mitigate foaming of the oil, and little else. Cynic in me says it's to help them start leaking sooner, but other than foaming control, should not affect the performance of the shock much unless you're road racing or autocrossing the car a lot. If you're doing that, you're probably better off with a better shock anyway.

Koni currently has a 20% off sale so a brand new set is $1100.
