A 3" lift that comes with replacement front springs will only give about an inch or so over the stock Offroad setup, ones that come with the spacer will give you 3" more, or a total of about 5" which is more than you want with the stock control arms. That said, if you want articulation, you need the longest springs you can get, so you can end up with a lower rate. Not sure about the Skyjacker springs, they don't give any detail about rates, but the 5" is probably lower in rate thatn the 3" which is again probably lower in rate than stock.
I'd say that going beyond 3" with 33s will look a bit undertired.
