The KYBs have a bad rep from the guys that really push their cars. I've had mine in the Charger since 2003 and never thought that there was anything wrong with them. I wrote earlier that I had a similar experience with my old bed. I didn't realize what a worn out piece of crap I had until I bought that new $1900 bed!
I still have the KYBs in the car. I may try another brand when cash allows. Edelbrocks were suggested by some, but I read that they are not making them anymore and the current supply is dwindling down....
