Not really an alternate just another piece of the puzzle.
(Note: I did TOO much reading on this stuff this weekend
).
Main players on the front end are springs, trac bar, sway bar and end links, steering linkage, shocks & stablizer, control arms.
You've previous identified the trac bar as an issue (its actually shitty bushings rather than the bar itself). You swapped coils and shocks as well as extended end links for the lift, for a 2" lift control arms should be fine unless a bushing has worn out.
In my case with the hemi (different spring rates than the diesel) I'm not sure if there is as much issue with the stock coils but I'm considering getting some power wagon coils which are softer than stock coils, they are 2" lift over stock which would keep the height about where it is now. The trac bar, links, and shocks are on my candidate list.
Anyways steering linkage is the last part of the puzzle, prior to mid 2008 has "Y" linkage and after that is "T" linkage, see picture below. The T linkage should hold alignment during suspension movement, the Y linkage the toe in/out can move as the suspension goes up/down.
Part numbers if you're interested:
52122362AG T Type Linkage
6505623AA Tie Rod Nuts X 3
68039930AA Pitman Arm If Built Before March 1st 2008
Also need a steering stabilizer, I don't have the number handy for the factory one since I'd consider an aftermarket one.
I JUST did this upgrade on my new to me 2003 2500. I installed it a week ago and just had it aligned a few days ago. WOW. Its amazing. My old 'y' steering wasn't too bad but I figured since the truck was new to me, i'd just take the hit and spend a few bucks up front. The steering is so much tighter and responsive. I want to say that the ride is a little less choppy too. I'm not sure how to describe it but I think having the two front wheels pretty much locked together takes away the little bumps and smooths things out - as much as a dodge can get mind you!!! You can do this swap in your driveway and they take it for an alignment.
I got a new pitman arm, steering stabilizer too. I have read you can get away with the older stabilizer but it was only $100 so I got it too. I just wanted to keep it all the same and not mix vintages and styles of steering components.
