I just received my custom 3" lift leaf springs from Alcan Spring in Grand Junction. I haven't put them on yet (next week though) so I can't say anything about ride quality. Build quality looks really good though. Customer service was great and the springs showed up on time. When I was getting quotes from different companies Alcan was just about $200 cheaper than Deaver. And from what I have heard the quality of the two is comparable. Figured I would throw that out there just to give you some other ideas.
