So far so good, I was sceptical about buying these shocks for my VTX 1300c because a lot of guys say that they are junk. I'm 260 and my lady is 150 and we had about 60-70 pounds of clothes and camping gear on the bike last week and we put on close to 2000 miles, I had the preload set on the 4th setting and it was super smooth compared to the 55,000 mile old stock shocks.
