Hey man,
Just wanted to pick your brain a little, because I know you went through a similar situation as mine with the Alcans.
I'm pretty much sick right now that I spent that kind of money on springs and didn't get my 3" of lift. Alcan is NO help, "Bill" won't respond to emails, and even if he did, they offer no solution.
Did you ever get ANY kind of resolution? Do you have any advice on getting it dealt with?
I'm at the point where PRG shackles are sounding better and better, simply because I'm ready to get this over with and move on.
However, like you, that doesn't solve the sagging issue. Bill told me VERBATIM when I ordered that the springs wouldn't start to sag until I got near the 400lb capacity I ordered. Well, that's not even close to correct. If I sit in the back (260lbs) it sags the rear almost a inch.
Really sucks.
