I found the lift your talking about, it's $675.00 , I just called them, and I guess its the same one on the onward?
I'm not sure if I'm allowed to post links, but here it is:

What about 1" Spacers to get the front wheels wider like this lift kit?
Jakes also has a 4" lift, and it says it can support upto a 23" tire also:
