These shocks transformed the handling of my '89 Sportster and I can go two-up with luggage without bottoming out. Now I have to upgrade the front end to match.

After messing up the first order by not getting the correct length. If you purchase these which I highly reccommend there are 3 lenghts available make sure to check yours first. Although JP howver as always was quite responsive with assisting and expediting the correct ones. The quality of these shocks is excellent and as far as the ride and handling on my 05 Sporty now all I can say is WOW. Between the new rubber on the front and rear that I put on a couple of weeks ago and these shocks. Its like a totally Different Bike!!
