Are you saying you are getting a body lift and are curious as to how it will work with your leveling kit.Your question is not entirely clear but I'll try.
A leveling kit it is a spacer that gets put under your front coils most of the time. If you are adding a body lift to a vehicle that already has a leveling kit it will simply install and lift the body away from the chassis. And your ride angle will be the same as before.
