I recently took delivery of my 2021 F-150 Lariat and noticed immediately the difference in ride when compared to my 2011 F-150. The new is a Supercab w/ a6.5 ft bed. The old was a reg cab XLT with a 8 ft bed. I believe the wheelbase is the same but the ride is a dream in the new. My question is are there differences in the suspension? I see some hardware on the rear wheels on the 2021 that wasn’t on my 2011.
