Thanks for the info. I haven't changed much on the truck in years and I'm pretty happy with they way it is right now. So I think that's all ok. Just got to decide if it's worth the extra money as far as smooth/soft ride goes. If I knew Alcan springs were better I wouldn't hesitate to spend the extra $$$.
What made you decide to get springs from Alcan? Was there something specific you wanted? What did you use for shackles, shocks and bushings?
