You will need them eventually. Although that RC 3.25” is probably a true 2.5” LOL. Just kidding.
I was on a 2.5”, added .75” pucks and waited a bit for control arms and driveshafts but did need them eventually. If you have the budget now, then get them now. I advise against rough country’s control arms though. +1000 on the Adam’s Driveshafts. That’s what I had. Best price on aftermarket shafts out there and same quality as Tom Woods, JE Reel, Coast…etc…
