Putting it in 4x4 mode

....knowing the libtards, try this idea. Dodge did that for liability reasons. The traction control and directional stability systems have a better chance of preventing ...well, all the fun stuff you just listed. Keeping the "send it" idjits in check.

Me? Like Bugs Bunny once said "if I do'd it I get a whoopin'. I do'd it anyway!"

You tell me why they wouldn’t offer 2wd then? Or…go on a trackhawk forum & see how they hold up for owners that have pulled the fuse allowing em to run 2wd & do those Smokey burnouts….

Trackhawk aside, It would especially make sense for the TRX to allow 2wd driving to help improve the abysmal gas mileage (im sure 2wd only would yield an extra 2-3mpg, significant for something that averages 9-10mpg mixed) & it would probably be a better option for towing. It would also be more fun in Baja type conditions, those pre-runner trucks are typically 2wd right?

I do crazy figure eight drifting donuts on packed gravel lots in my Raptor, & if I had a TRX that I could throw into 2wd you better believe I’d be doing even crazier drifting antics on that lot w/ the TRX haha

Simple way to fix that … just pull the front drive shaft. Im sure the trx would be fine. The semi float dana 60 rear and ZF trans are both pretty robust. I guess perhaps yea the front axle shafts would be vulnerable given angles and travel but those are equally vulnerable on a Raptor. So yea im not a trx fan boy but I'm not buying that it was built with a fragile drive train. Dont forget a lot of goons fit spacers and lifts with big tires on trx . That is probably responsible for more driveline breaks than anything else.

We are talking about the rear drivetrain components not being up to task to taking the full brunt of 700+hp to the rear wheels only, I already know the front end can’t handle the power w/o distributing the bulk of the power to the rear lol

The 1/2 shafts/axles, yoke & pinion, rear driveshaft & diff is what they’re worried about most likely

This is why ALL that stuff gets upgraded when you go to a heavy duty 2500 Cummins

I can’t think of ONE logical reason (other than protecting drivetrain components long term) for the TRX to not offer a 2wd setting. I can think of plenty of reason why they WOULD want to have it available - esp knowing the Raptor does, the power wagon does too….

Nope…only logical reason I can muster is they were worried about TRX owners grenading those components on the street doing hard launches/burnouts/towing etc

Did some searching and this old thread was the closest thing I found to an answer.

Can anyone confirm that the 4wd Auto in a gen 3 Raptor is in fact different than the other f150's 4A? I used 4wd Auto today after some rain and though I was driving at slow speeds and did not feel any slipping I could feel the drag on the drive train as if I was in 4wd(yes I double checked it was in 4A).

The animated powertrain graphic showed the front diff and axles spinning. I also got about 2mpg worse gas mileage driving 60mph vs when I changed to 2wd mode.

My 21 King Ranch Powerboost did not exhibit any of these things. It felt no different in 4A unless actually slipping and mpg was unaffected. I can't remember for sure but I don't think the front drive train was moving in the graphic unless power was being sent that way but not 100% sure.

I admit, I am not a fan of 4A and as such, have not messed with 4A in the Raptor. The last couple of Fords that I did use it on were a 2005 expedition and that sucked. On a slippery road (snow) it would let the rear wheels rotate about 1/2 a turn before engaging the front. Just enough to make the rig break loose and try to spin out. No problem in 4H. Second was the 2024 Edge we had for a short time. 4A in that seemed to work just the opposite. Example, coming up our snow covered driveway, the front would spin out with little power to the rear resulting in the damned thing going sideways in the drive and stuck.

In summary, in 4H, front and rear are always in sync except when you choose a different path for them such as a sharp turn. As for the new Explorer we replaced the Edge with...so far off road has been great and I have hopes for it this winter. As of today, we are just weeks perhaps days from snow so I will know for sure if it can manage its 4A better on slippery stuff.

You do have me a bit curious though so when the snow flies, I may try 4A in the Raptor.
