We have the 416's on our 02 RK,10 to 12 lbs is just right for the wife and I.Our combined weight is 350 lbs or so.The ride is excellent.
Can't really say I've ever had good quality shocks before what would the characteristics of an "excellent ride" be? I was quite happy to have a ride that doesn't clunk anymore but sure would like to experience an "excellent ride".
