What all is involved in changing the coil springs in a 98 Chevrolet C1500 4x2? What parts have to be removed?

I want to add either 2%26quot; taller coil springs or 2%26quot; coil spacers, but i want to know what all is involved in this before i order the parts. Do the spindles have to be removed? Shock absorbers? Control Arms?|||disconnect shocks and remove lower control arm and the sway bar links have to com off and is easier to do on a hoist|||you remove the shocks one at a time and you might have to disconnect the swing arms
