Anyone know of an aftermarket or homemade bellypan for making the underside aerodynamics better on the 6.7s or 5.9s. I know my percent of power used to move the trucks goes up about 15% going from 55 to 75mph. Thinking that a low airdam or smoothing out the underside might save some of this power. Seems the big three or doing more research on the underside air flow on new trucks being developed.

 

no but they are easily made with a little bit of work and sheet steel.....

 

Some needs to make one of those I 'll bet that there is a bigger market for them than most realize.. Just my .02
