So far I think this is an absolutely gorgeous design and will be very effective in relieving that heavy rocking feeling on winding roads and mountain passes. Turns help too. There will be a good test in a few weeks. The delivery time was much better than expected. Package also received in good condition. Thank you for developing a great product at a reasonable price. One issue I had was that I had rear air springs and that was causing a frame mount issue. I had to modify the upper support bar to allow the lower brace to move back and over the spring brace which is bolted to the frame. But everything went well.
