Hello all, I've been researching the frame and axles on my diesel truck trying to understand payload on them.
It appears the diesels have the highest front GAWR at 3750 that you can get on this generation of f150. We have U code springs though at 553 lbs vs the HPPD Y code at 600+.
For rear axle I have GAWR at 3800. But it is the 9.75B axle that is rated at 4500 from the axle production line. I am curious if anyone with 20 inch wheels got the bump to 4050 that the max tow gets on the 3.5 with same axle and springs.
The differences between HD frames and HPP frames on 2019+ HDDP trucks seems mixed on the HPP markings still being used as I have seen reports of HDDP trucks saying HD frame on the sticker in other forums.
My truck has a GVWR of 7100. Does anyone have higher? The HDDP trucks this generation top out at GVWR of 7800 with a 3 leaf pack, 3.73 rear end, different axle shafts and a larger diff cover to hold more fluid.
What I have been trying to figure out is if the higher cost of the diesel is partly due to also getting the higher spec components from the HDDP trucks. I could see Ford not rating the higher payload ability if true due to either the engine not having capacity and/or not wanting a diesel 1/2 ton that could cut into F250 sales.
I think many people if choosing between a 250 and a f150 with high MPG, 11,000 towing and 2000 payload would choose the f150.
