So the drivetrain is lifted 2" only .. I'd just use the stock A-frame .. in fact I do!
If you fit the spring spacers too, to take it to 4" drive train lift, then that's where I'd look at an elongated A-frame. Dunno what the dimensions are, but it needs to be right or the diff is likely to point down more than it should. Similarly at the front, you might need 6 degree arms for the 4" spring lift, but again, the caster correction also points the diff down a little .. I'd also suggest at least wide angle props, maybe lengthened or spacered to suit ... and carry spare UJ's when you're out ..
A lot of this needs working out on the vehicle, some setups, like RAC etc are already figured out dimensionally to work reasonably well with no more mods, but adding bits needs to be looked at critically if you want it to work well. Having said that, many setups will work, not optimally, but good enough to give extra wheel movement and flex without too many hassles.
