What are you going to do with the rest of the truck? It needs to be built as a package. I would do a dropped axle, but I'm good with a 235, granny 4 speed, no radio, simple heat, and stock trim. If you're going billet everything, 10,000 watt stereo, aftermarket A/C, shiny paint, and a crate motor an IFS would be more appropriate. It's all in the package.
