Ford's heavy-duty pickup trucks get a new turbodiesel engine, redesigned interiors, and an exterior facelift for 2008. Mainstream Super Duty models include 3/4-ton F-250s and 1-ton F-350s. The line also offers F-450, 550, and 650 versions. F-250 and 350 are available in five trim levels. XL and XLT offer a 2-dr regular cab, an extended SuperCab with rear-hinged doors that don't open independently of the fronts, and a crew cab with four full doors. FX4 and Lariat trims are available as SuperCabs and crew cabs. The top-line King Ranch is a crew cab only. The Harley-Davidson edition is discontinued for '08.

Regular cabs have an 8-ft-long cargo bed; SuperCabs and crew cabs have 6.75-ft or 8-ft beds. F-350s are available with single- or dual-rear wheels. A 300-hp V8 engine is standard on all but the F-350 dual-rear wheel crew cab. Standard on that model and optional on others is a 362-hp V10. Also optional on all F-250s and F-350s is a new 350-hp turbodiesel V8 that replaces a 325-hp turbodiesel V8. For all engines, 6-speed manual transmission is standard, a 5-speed automatic is optional. All except the FX4 are available with rear-wheel drive or 4-wheel drive that should not be left engaged on dry pavement, but includes low-range gearing. FX4s are 4WD only.

Lariat and King Ranch models have specific trim and are available with a navigation system. A sunroof is optional on all crew cabs except the XL. Also optional is rear obstacle detection. New-for-'08 options include a stowable bed extender, retractable tailgate step and grab bar, and power-folding/telescoping side mirrors.
