I'm pretty sure your a z85 or zq8(meaning that you have coil springs), so your lifting with the CST lift spindles. I may be wrong, but I think that the crossmember is only an issue with z71 or offroad models(have torsion bar suspension).that use subframe lifts. Now you will have to lower the carrier bearing, but CST provides a bracket and instructions for that.
I have a crew cab with the CST spindles, and don't have a clearance issue.

It's only an issue with trucks with 1 piece driveshafts.
