Thanks for the replys,

Domman56,

Yes the 4x4 is an important part of this truck. It is all stock, I have a partial upper grill block and the body to frame rails covered underneath. I run the tires at 40 psi on the highway.

Moonmonkey,

An easy to remove air dam might work but I worry that with a high ground clearance I may increase the frontal area so much that I would be better off with a smooth underside.

I am trying to decide if I want to fair the axle with an upside down airfoil shape behind it tapering to the bumper in the hopes that the air disturbed by the axle will reattach or if should just make a flat panel under the frame rails. I just haven't ever seen this attempted. The angle should eliminate any clearance issues...
