Since you have a 600/6000 already, try it first. No point spending money if you don't need it. You're well within your trucks' limits by the sounds of it so you're not going to hurt anything. After trying it you can always just upgrade the bars if you find the ride too soft or are having difficulty transferring enough weight.
Not with an Equal-i-zer you can't, he'll need a new head as well so it would be better to just sell the 600 and buy a complete new 1000 ... if he had a Blue Ox Sway Pro he
could upgrade by just changing the spring bars.
