Skyjacker Suspension Lift Kit Component 1975-1978 GMC K15 Suburban - C140A

Yes. Any change in ride height changes the alignment; set it once the kit is on and the truck has been driven a short distance.

The maker states the largest tire the kit is designed to clear; going larger can need trimming or more lift. Wider wheels with less backspacing also change what clears.

Taller lifts change the angles of the driveshaft and CV joints, and kits made for that height include the parts to correct them when needed. A leveling kit that raises the front a small amount usually does not.

A leveling kit raises the front to match the rear and keeps the stock springs and shocks, so the ride stays close to stock. Larger lifts with new springs change the ride more.

Some kits reuse the stock shocks and some include or call for longer ones; the Part details and the maker's guide on this page say which.

Trucks with headlight leveling, adaptive cruise or a forward camera may need those systems re-aimed after the height changes.
