The control arms included with this kit do not correct your UCA angles when increasing ride height. They merely allow for more travel once you do add front height, since their uniball joint won't bind like the factory UCA's balljoint. Leveling your truck will throw off your UCA, LCA, and CV angles to some degree, but as long as you stay 3" or under, you won't see excess wear or a significant decrease in drivability.
