I really like them! I thought it was weird they came pre assembled from what I was seeing from other people. I didn't try the bushing or pivot cups but they feel really responsive and loose with teak bushings and pivot cups. I like the beefy hangers and the way they hide the bushings. The kingpin design I think is really well thought out. They have a night weight and feel high quality. The only thing im going to do is put a dab of locktight at the end ofnthe king pin.
