Weight cost of 4WD on F150?

As the subject says, can someone tell me how much payload is eaten by having 4WD on an F150? I'm referring to the transmission itself, not the optional FX4 skid plate, etc.


Thanks

If you plan on towing a Rv you want the insurance of 4 wheel drive.
Many campgrounds have dirt / grass sites and roads. When you end up with a rainy week you may need the extra help.
Just my two cents.

Hard to answer your question as framed. As far as the transmission goes, 2021 F150's, both 4x2 & 4x4, have the same 10 speed. So, the transmission is irrelevant. Max payload depends on WB and Trim Levels.

Extrapolating from the max payload of a 6750 GVWR 145" WB RWD SuperCrew in the same table, an HDPP 4x4 XLT SuperCrew is a net gain of >600# over my current 2016 145" SuperCrew Lariat which has a >1700# payload as built.

I know I can't compare them directly because an XLT and Lariat will have different GVWs, but my Lariat has a GVWR of 6800#, so it's good enough for my purposes of deciding whether ordering a new HDPP is worth it. The extra payload isn't the only thing I'd get but it is part of the calculus.

My question is intended to compare 4x2 to 4x4, apples to apples. Timfromma provided the information source I needed.

Wrong. Can get the 157" wheelbase on non-HDPP F150's.

I misstated my intent. I meant that, if you order the HDPP (7850# GVWR), it must be 157" WB, not that 157" WB is available only as HDPP. If I erred, I stand corrected.

You will lose alot of torque on your rear wheels when using 4wd since power is transferred to the front. I once got stuck with my camper in tow and using 4wd made it worse. I had better traction using 2wd.

I have extensive 4WD experience and not once have I ever had better traction in 2WD. Unlike AWD vehicles, there is no shifting of torque between front and rear. The transfer case locks front and rear together, providing equal power to front and rear.

Traction was probably the wrong word. Torque is what is lost. The engine and tranny can only put out so much and in normal 2wd, all of it is directed to the rear wheels. In 4wd, it is divided between the front and rear wheels.

When I last bought a new TV. 2019 Ram.

The difference in the 4X4 compared to a 4X2. With the same options was right at 600 lbs more for the 4X4 version.

Worth every penny. err pound.

Good Luck.

Unlimited amounts of torque are of no use if there is no traction. Traction on the front is usually greater due to the weight of the engine and the ability to turn the wheel side to side. An additional benefit or 4WD when towing in low traction areas is that you have a two speed transfer case which does act a torque multiplier through its lower gearing. Most modern trucks also benefit from locking or limited slip axle options that even further enhance 4WD operation. If you do not have or do not like 4WD, just make sure you have a reliable emergency road service you can call.

I would never buy a 2WD for towing a TT. Driving out of a campground in Penn after a sever thunderstorm, I had to lock in FWD to get through the gravel that washed down the road. I have also used FWD (low range) to back up steep driveways to get into my campsites on several occasions.
I also like driving on the gravel roads in and around Moab. Without FWD I would never go off road.

One time when boondocking it rained heavily at night. Trying to get out the next day would have been impossible without the 4 X 4.

FYI the F150 skid plates weight very little, under 20lbs if I'm remembering correctly.

They also add > $1,000 to MSRP and I don't care about most of the stuff.

#1 that makes no sense.
#2 I have 4wd and a locker.

Fx4 is not required to get the 4wd. Regular 4wd does not have the 'skid plates'.

I know and have no plans to buy them. I was responding to Flyflotrim's comment about the added weight being small. The weight may not be much but the cost is more than I'm interested in paying, especially for something that I don't personally find value in.
