Anyone out there with a 2004 and up F150 5.4L V8 upgrade to an aluminum driveshaft? If yes, was it a big difference? Anyone with a Supercab 6.5 foot bed switch from a two piece driveshaft system to a single? Pro's and Con's? I got a supercharged engine and just want to put more of my power to the pavement by reducing the rotational weight of the driveshaft. Thanks for any info.
