What to Do with Suspension and Driveshaft?

[Red66C10]

I have a Turbo LS 66 C10 with Air Ride Suspension and Single 3.5" aluminum Driveshaft. Put down 502RWHP at only 8psi boost...Currently running 10psi.

I want to be able to lay frame and keep good power.
I plan to run the truck at the strip a few times a year, so I want to know if I can go with a 3.5'' 2 piece shaft, or is there another crossmember that allows the Single shaft to go all the way up next to the floor? Im just lost with how to get this done.

Another question is: Will the Air Ride suspension be OK for the drag strip?

Would really like to hear from experienced people..Thanks
