Air ride without steering and bed modifications? (1980 C15)

[evan]

I'm planning a new project with a friend on a 1980 GMC C15 and we're thinking about using air ride. Neither of us has used it before. Our goals are to improve handling, cruise at a ride height similar to a 4/6 or 5/7 static drop and then park as low as possible without steering & bed mods. Is it still worth it to spend the money on air if we're going to leave the steering and bed stock?

I see the Ridetech level 1 kit reuses the factory control arms so I'm assuming it's not necessary to modify the steering. Does the rear four link in that kit require bed modifications? Are there other options we should consider?

Thanks for reading.
