Maybe helpful if we identify which struts we are observing the gas/hydraulic behaviour. I think we are comparing apples and oranges and coming up with different conclusions.

I've installed several sets of koni into bogie struts. All gas. Rears, all gas.

I note the pelican description for koni shocks says gas for bogies, but says nothing for koni struts. I suspect that the koni strut inserts are are hydraulic.

Quick question: Do the gas shocks prove to have a big advantage in the rear over the hydraulic ones? If so what is it? I always thought that they charged them with gas (nitrogen) to keep the shock oil inside from foaming when under intense dampening. Is their really that much movement going on to cause these things to foam up? Seems like a sales pitch, but i certainly could be wrong.

I did it

I very recently had to replace my fronts. My car came with konis from the factory. I talked to the koni cust serv rep and this is what he told me:

Quote:
Mike,

Actually, you can use the 8641 1039 (externally adjustable front insert) in the
Koni housing but you have to use a different gland nut (the cap that holds in
the insert in) than what is included. If you want the externally adjustable
setup, go ahead and order them. Once you receive them, please call us and we'll
get the correct gland nut to you (they're about $10/each). I will need to know
a measure of the insert that you receive though as some recent production
changes make a difference in the exact part number you need. Thanks for writing.

Gordon
That is the same part number as the inserts for the Boge struts. I talked with my mechanic about it, they ordered that part, and installed them.

Best upgrade of the day

I think technically these would be considered 'yellows' but since they are in the original housing they are still plenty red.

I would say I am happy, but saturday they started squeeking again and I haven't had it back in to see what's up! Wish I could give a less ambiguous answer.


QUESTION: does anyone know if externally adjustables are available for the back? for koni housings?

OK....here's another variation ( ! ):

I had Boge hydraulics as original equipment all around. For my replacement, I wanted either Bilsteins or Koni's , but did not want to face having the car raised by the new gas pressure shocks.

I did this....

for the front, went with normal, red, low pressure gas Koni's ( inserts for Boge), externally adjustable for rebound damping via a removable plastic knob on the top. The low pressure did not cause the car to be raised.

For the rear, went with *special*, yellow, Koni Sport, *also* adjustable on the top with a removable knob, but these shocks are hydraulic, so the car won't rise up under gas pressure. The more common red or yellow Koni's are high-pressure gas ( just where you don't want them to be HIGH pressure if you fear a raised car---hard to re-index the rear compared to front). These shocks are something like 2" shorter than stock so that if I DO lower the car, I won't have shock travel problems. Again, by comparison, the normal high pressure rear gas shocks ( red or yellow) don't have the removable knob on top for adjustment...you need to remove one end of the shock to adjust.

I don't have the part numbers available in front of me know, but I can get them. Because of the special nature of my purchase, went with Jason at Paragon Products, a specialist in Koni applications.

Good points Wil, my sports did infact raise the car around one inch. I think that was the second time of many that I had to reset the ride height!!!!!

So, just got the Koni reds for the rear, they DO NOT extend on their own. Is this in fact defective?
