The 2021 Ford F-150 is as reworked as you can get without going completely back to the drawing board. Ah, but dig deeper and you'll find that Ford went through its best-seller with a fine-toothed comb, making small but impactful updates nearly everywhere that together add up to a substantially improved truck. There's nothing fundamentally different than before, but engineers widened the track and tread width, the ride height was lowered 0.4 inches, the engine and transmission mounts were enhanced, the front suspension got a more beneficially located stabilizer bar, the rear suspension got monotube shocks and new leaf springs, the electric power steering system was retuned … we could go on.
