I paid $400 to coat my front crossmember and rear axle housing. The uppers and lowers are a two stage reflective chrome with a clear top coat. I did the spindles and springs myself at my shop, but left the big stuff to the pros. Also included in that price was the front sway bar, all steering linkage and the rear Lincoln 9" housing.
I think if I was just coating the cross member and the arms $200 would be a good price.
My powder coater is very good and takes the time to zinc coat the items first to give it is really good rust preventer if something gets chiped.
