I bought an Advanced adapter SYE and the RE 4.5" Extreme Duty lift for a YJ. The delivery was a little slow because RE was in the middle of a move to their new location. There prices were good and we used the cheapest method of shipping. I don't think they keep everything in stock so some items are shipped directly from the manufacturer. If you can afford to wait an extra week I think they are a good place to order from. They had the lowest prices we could find at the time.
