An alignment is part of a Silverado 1500 leveling-kit installation, not an optional finishing touch. Raising the front suspension changes the relationship between the wheel, steering knuckle, control arms, and strut. The amount of change depends on the truck, the kit, the installed height, and the condition of the original parts. A 2-inch label on a box is not an alignment specification.
For the kit choice, identify whether it is a spacer, a replacement strut, or a package that includes upper-control-arm hardware. Compare its application by model year, drive system, factory suspension package, and the height at the wheel. A Trail Boss or AT4 already sits differently from a standard-height Silverado, so applying a kit's advertised lift to the trim badge alone can lead to the wrong expectation. The ReadyLIFT 66-3921 and Rough Country 1321 product pages are comparison references for different applications and geometry packages; use each listing's current application guide and exclusions to match the kit to the truck.
After installation, inspect the front suspension at normal ride height and through its available travel. The technician should check toe, camber, and caster against the alignment range for that exact Silverado, then print the before-and-after readings. Look for contact or binding at the upper-control-arm ball joint, coil spring, tire, brake hose, and sway-bar link with the suspension unloaded as appropriate. If the alignment cannot be brought into the exact Silverado's specified range, confirm that the shop used the truck's year, trim, and suspension package rather than another model's specification sheet.
Caster affects on-center feel and steering return; toe has a direct effect on how the front tires scrub as the truck rolls. A truck that pulls, wanders, has an off-center steering wheel, or develops uneven tread after the install needs another inspection. Tire pressure and wheel offset can also change the feel, so record those details when discussing the result with the alignment shop.
The Steering Angle Sensor may need a relearn or zero-point procedure after suspension work, steering-wheel correction, or an alignment, depending on the truck and the scan tool's service instructions. Ask the installer to check the StabiliTrak system for stored faults and to document any calibration performed. Headlamp aim deserves the same attention: removing factory rake can alter the beam height, and the lights should be checked with the truck on level ground.
