2 things that should be considered when changing suspension.
First and foremost are pinion angles.

The other is torsion bar key altering. I have never heard good things from anyone that altered the keys in any way. One of the problems shown here in this video is obviously the opposite of what you want to do. However, that direction can also have consequences.

You can dig further into these 2 areas to understand better the problems. I see people every week that have pinion issues on raised trucks. The ones with altered keys don't understand the ride quality issues and think they have to live with the ride.
Good luck in your endeavors.
