Wow, 2 normal sized guys couldn't even ride in this go-cart without going over it's GVWR. WOW!

...or damn close.

3600-pound fGAWR.



Driver and about 20 pounds of misc. stuff in the cab, no other passengers, and about 200 pounds of net gain in bumper and winch hanging off the front end (160-pound bumper, 67-pound winch, less factory bumper weight around 30-45 pounds). A lot of off-road style bumpers are heavier, some as much as 210 pounds before the winch, and my 67-pound winch is with synthetic rope; steel cable would add another 20-25 pounds.

It seems like the 2015+ trucks might be worse off. Mine has a 3900 lb FAWR and is at 3440 lbs but thats with 33" Wrangler duratracs and a couple other misc things. empty with a full tank of gas. I dont think the new trucks lost a full 300 lbs off the front end since the engine and suspension are still the same(at least the same as my 2014), and only the body panels changed.

Interestingly, the 2015 Ford docs show a 3750-pound front suspension option available on some non-HDPP F-150 configurations (.727 wire diameter and 553 lbs/in springs as opposed to .712 diameter/513 lbs/in on the 3650-pound suspension), and the 2017 Ford doc shows the 3.5L EB/157" 4x4 has having a 3650-pound fGAWR.

I'd really like to know if (a) there is a 3750-pound fGAWR variant (non-HDPP), and (b) what components are different—is the axle itself different, or is it only springs? hubs?

Edit: hmm, page 48 of that Ford doc shows one front axle without footnotes, with a 3750-pound capacity—so it may be the same except for springs and (with respect to HDPP) wheels and tires.

Knowing the differences on the HDPP variant would also be interesting, but I'm assuming there are more differences there and it's not just the springs.

If it is just springs, then going to an aftermarket front suspension should mostly eliminate the fGAWR concern with the off-road bumper. I'd rather not spend the money that I will if I go to a full aftermarket kit, but it seems like just swapping springs is likely to be a fair bit of time and money for less benefit.

Edit2: also very interesting: the 2017 Ford specs doc shows two front springs rated for 3750 lbs at the ground:
a) .727" diameter, 553 lbs/in on a non-HDPP config
b) .744" diameter, 633 lbs/in on an HDPP config

So it would appear the 2017 HDPP is still limited to 3750 lbs on the front axle, but that would also suggest that just swapping to stiffer springs would be enough to put the 3500 lbs I have on the front axle comfortably within limits and still leave some room for occasionally having a passenger or two.

Mine is a 4050 lb front end! ...Haven't seen one like it yet lol

mass-hole

so your fawr is higher than your rawr? Weird. I have heard a few folks with 4050 lb front axles. I think one was a 2014 supercab ecoboost with max tow on the other forum.

I would imagine the 6.2L trucks might have it too since they are iron block motors and weigh several hundred lbs more than the ecoboost/5.0.

A 4k front axle would have to be pre-13th generation on the F-150 line; according to the Ford docs, the front axle itself is the same across all variations (including HDPP) and limited to 3750 pounds at the ground.

Simnut

Pre 13th generation? Mine is a 2014.....does that fall into that category then? I have lots of weight room on my front end and it's been suggested here I get a plow set up for it. Been kind of snooping around already lol. The only issue here is.....we are lucky to get a week of snow! lol

kbroderick

Yup, 13th generation would be an aluminum-bodied truck. The trucks got lighter but the GVWRs and GAWRs also dropped.

Let's keep this going. It's been a valuable resource to me.
