Need More Info
What lift are you talking about?
What are the specs and details on the truck you have (year, model, motor, 2WD or 4WD, etc.)?
Lifts don't "damage" the suspension...well, unless there's an incapable imbecile that installed it. You have to do it right & safe.
Aspects like your driveshaft angle, camber of the tires (amount of lean of the tires toward the vehicle), and handling characteristics of the moving vehicle are some things that will change...
Welcome to TRS, BTW.
