I bought my K75S with a leaky Works shock. They rebuilt it for me, and installed a standard length rod(it had a 1/2" shorter rod). Total cost was very reasonable considering that they replaced the seals, bladder, and rod.
My only complaint was that they had quoted 2 week turnaround and it took just over 6 weeks, and it took a couple emails to get them working on it. In fairness, I had sent it in in December just before the holiday season.
Overall, I am very pleased with their service and would recommend them in a second. And they not only service their own stuff, but they will work on other company's shocks, too.
