Best mods for mpg
#12
Service body has been removed and I found that my new truck has air bags. I talked the shop mechanic about them and he didn't know they were there either (the same guy that said this truck needed a pump and was not worth fixing). So with that said, I assume that these are considered overload or leveling air bags. She rides like a lumber wagon with 20psi in them. Only slightly better without and no box. If I get longer rear shackles and lower the rear ride height, I think this will improve aerodynamics. I will have to raise the air bag frame mounts if I leave them in. Any thoughts?
