So here is the comparison I found:
With the Gold Koni laying on the bench, they are very hard to pull open (extend). Then they stay extended by themselves. But they collapse pretty easy.
The yellow Bilstein collapse pretty hard, but as soon as you let go they start extending, all the way to their limit pretty quick, and with quite a bit of force.
This tells me, that in a big dip, the Bilsteins actually make the coach raise (porpoise) zero damping, but the Koni's actually dampen the raise.
It's like the Bilsteins work the opposite of what is needed
I guess the proof with be in the puddy when I'm done and drive it.
Here is the reason you want to check the bolts. Everytime our coach would do a big porpoise, it would squeak

Dampening on compression adds to effective spring rate-- making ride stiffer.
Dampening on extension dampens, but does not add to effective spring rate.
That is why the Koni's are easy to compress and HARD to extend. That is what you want.
Yes sir. I read everything on here, but wanted to know for myself. So many different opinions. Mostly pro Koni. But that could have been because the shocks were bad in the 1st place.
This makes total logical sense now why the Koni's work so much better on our coaches.
Our coach rides fine, actually really nice. Just wanted to help with the porpoising. Sometimes I think we are going to lose the Jeep!

Me thinks shorter 36' and under suffer from porpoising more than longer coaches. On those washes on 95 heading towards Quartzite from yuma, shocks ain't going to help that at 70 mph.
Wonder if the squeaking were your torque rod bolts and bushings,the steel spacer around the 1 inch bolt has a tendancy to rust
weld to the bolt over time.
Bruce, I'm sure a 36' has a lot to do with porpoising. Actually the dips on 95 don't really bother it. It's the short ones I don't see. It really isn't that bad, just experimenting.
At any rate, having shocks that push up certainly doesn't help.
Don't let the gators get you in swamp land! Give Macy and Linda a hug.
See Ya

Both great shocks. My previous owner, put two Bilsteins in the very front and 6 Koni's. Seem to be fine on my 36
