I bought a set of 944's for my 2013 Road Glide. Once I received them I installed and noticed one of the adjusters was very hard to adjust. I also could not get enough sag with the HD springs. Their site isn't really clear on which way to go. I called them and explained the issues I was having. I was told wait til end of season to send them in. They would take care of both issues. I called today I was told I would have to pay for parts and possibly labor. So by the time I send them and pay for shipping and repair they will cost me well over $100. Wish I would have bought something else. Live and learn.
