I took a hard look under the truck today. It's about as un-aerodynamic as it gets:
- Front sway bar is inder the axle and in the air stream
- Transfer case skid plate is way below the transfer case
- Fuel tank shield protrudes about 1.5 inches below the tank
- Spare tire in the airstream, but easily removed and stowed in the trunk
- Helper springs and jounce bumpers (not really in the air stream, but heavy)
- Muffler: is a more aerodynamic shape available in the aftermarketp?
- Rear
- bumper protrudes 4" under the tailgate across its full width.
Most aero improvements cost money, but removing stuff is free. I was thinking of just removing a lot of the junk under there as an experiment. Anybody think that it's worth it?
