2005 Ford F-150 FX4 Regular Cab 4x4 6.5-foot Styleside box — 5.4-liter three-valve Triton V8
Ford's 2005 brochure and specification matrix lists this FX4 chassis and powertrain for the U.S. F-150. The V6 cab and transmission restrictions, series-specific V8 availability, Flareside boundaries, 163-inch-wheelbase payload configuration, and King Ranch package are preserved rather than cross-multiplied.
