Heck, you think that's bad, try mod'ing an Armada!!!! Dude, your Titan is far easier to work on, find service techs who know the truck, and work out kinks on than on an Armada.
If you got a PRG, then call Greg!!! If it's a different brand then you could sell your 2" and get a 2.5" then you'll likely need to replace the UCA's.
If inconsistencies are gonna piss you off then you better trade it in for another truck to mod because these trucks have a LOT of inconsistencies. Everytime you change something, you're opening up a whole new can of unknown-WTF. When I put on the 6" Lift, I couldn't fit my rear wheels on. I had to go fork out another $270 to space the wheels out further just to get it driveable again and I thanked the good Lord that someone had them locally in stock. Talk about a pisser after having already spent $1600 down the drink.
Good luck with your adventure, this is how chest hair is earned.
