Red Koni shocks

Hi there,

I dropped the front shocks last week. These are red Koni as usual on the MSE. I was surprised there is almost no damping action in compression. Extension is well damped even at half setting but nothing in compression.

Is this normal or do i have to replace the shocks ?

Thanks

They are most likey in need of help and have been on there since 83. Koni will rebuild them but its cheaper to just put them on the shelf and buy koni yellows

You're talking about the front struts right? Koni yellow make a world of difference!!!

Re: Red Koni shocks

Ok so we agree they should be damping compression as well as rebound.

Thanks guys !
I'll get Koni yellow.

Of course. Otherwise you get the effect of "jacking down" when going over a sustained series of bumps. That familiar feeling where you hit the first bump and everything seems OK, butt as you hit more and more bumps, the car feels "lighter" and lighter with each bump because the suspension and wheels are getting jammed up toward the top of their travel faster than the car can fall down onto them (acceleration of gravity is 9.8m/sec˛, that's therefore as fast as it can "fall"), until it acts like you're skating on ice. In effect, the ride height actually changes during that time. Then after the bumps are over it seemingly goes back to "normal".

While compression and rebound settings aren't usually identical when optimum, the complete lack of one or the other is a serious problem.

Re: Red Koni shocks

That's the reason why i was asking.
No compression damping seems a bit weird for high speed driving.

I never drove that car so i couldn't say how it behaves. I'm working on it to get it back on the road.​​​​​​​
