In the most extensive redesign of the F-Series in 17 years, the chassis received fully independent front suspension, ending the use of Twin I-Beam front axles. Sharing only the transmissions with its predecessor, the 1997 F-150 received a range of engines new to the F-Series, including a 4.2L V6 and 4.6L V8; a 5.4L V8 was added during 1997. Introduced in the full-size Crown Victoria/Grand Marquis/Town Car sedans, the Modular/Triton V8 was the first overhead-camshaft engine ever to be installed in a full-size pickup truck.
