I changed my damper at 575,000 miles on a 2004 ISX.  I noticed no difference.  That's a good thing, because the old one was not worn out so bad it was causing damage.  Bruce took measurements from my engine and had the balancer made for the ISX.  I put the balancer on at 650,000 miles and by putting my fingers on the engine before and after installation the vibration was softened.  Think smooth waves instead of choppy waves.
