These shocks felt good for the first 500 miles and then suddenly became very soft and spongy, just as bad as the stock ones they replaced. I had replaced them shortly before a 2000 mile trip. On the test ride they felt good but on the trip they failed miserably. I was riding solo with only a 40lb bag on the back seat. I tried adjusting the preload of the shocks on the trip but made little to no difference.
