I see in a different thread someone asked the same question about the Different GCWR and Tow ratings. Seems others had noticed the same things without any explanation. A theory was proposed that the difference could be 18" vs 20" wheels similar to the situation stated with the ecoboost and max tow pkg. It would be interesting to know if those with 3.55s and 18" wheels have a sway bar or not vs those with 20" wheel?
2018-2020 vs 2021
Hello, I am new to the forum. I have had many Ford Trucks since 2001. 2001 F350 V10, 2003 F350 7.3 PS, 2005 F250 6.0 PS, 2008 F250 6.4 PS, 2009 F150 5.4 v8, and now have a 2004 F150 5.4 V8 and a 2013 F150 3.5 EcoBoost. Between waiting for the market to settle and getting finances right I may consider selling my 2004 5.4 and looking for a 3.0 Powerstroke. Would love to have another Superduty Diesel but prices are just out of my price range these days. I have searched a lot of different places for anyone with real world comparisons between the 2018-2020 vs the 2021 3.0 Powerstrokes with not a lot of info. I know that mechanically there aren't really any differences between the two generations. And I see the differences that fuel economy was rated for different years and trim levels. I am wondering if anybody has had any real-world experience with the two different generations as far as drivability/rideability, power, fuel mileage etc.? Also, something else I can't figure out is for the 18-20 models with a 3.55 rear end CC 4X4 there are two different GCWR and two different tow ratings. For those years no specs or publications from FORD explains this difference and does not list the 3.0 with an available MAX tow package only the ecoboost. So, what's the difference? I see for the 2021 models the difference is an available MAX tow package. Thanks in Advance

I have the 3.55 gears and 18” wheels on my 2021. I’m not sure about the sway bar you are asking about. There is one on the front end but not the rear axle. Only thing that I’m not happy about this truck is the tires. The Michelin Primacy are not a light truck tire. Way too much flex in the side walls. You really feel it when towing and a big rig passes you. It’s much better running 40 psi in the rear and 45 psi in the fronts. But not great. I’ll be stepping up to a set of 8 ply light truck tires when these wear out.
My '18 felt like it had a lot more power than my '21 and would easily spin the wheels under hard acceleration.
