I didnt try locking the diff when 2wd-ing up to the mountain. I should play with that next time to see the difference. Of course when the wife isnt with me... She was all paranoid for no reason cause I didnt have it in AWD.
yours will disengage out of a locked rear in 2wd around 15-20 mph. They do it for “safety”.
It doesnt make mush difference anyway. I make sure to get it in my trucks when I order them and I’ve had a lot of instances pulling snowmobile trailers where I get “stuck” in 2wd and think I’ll get out by locking the rear without 4wd and it hasn’t worked most of the time.
It it is really nice to have to when you pull over to put chains on pulling a trailer up hill and one tire is in soft snow and the other is on the hard pack road. Alls when you’re messing around off-roading on off camber hills nut overall I’d say it usefulness pretty limited.
"need" is a strong qualifier but i'd rather have it and not need it than need it and not have it. i've only had it for 4-5 months so i haven't encountered a situation where i needed 4hi or 4lo yet. 4hi they said to only use in dry/straight but they didn't know the center diff was a torsen, and 4lo just to get out from being stuck. i also have a center diff lock button, i guess just to electronically force a 50:50. not sure how much that would really help vs whatever the torsen normally splits at, would have rather had an actual rear diff vs open in both front and rear. all my towing has been in the dry/wet, so haven't towed in snow - that sounds challenging.

Not sure how the F150 is setup but my raptor has no speed limit for the locker if I throw the truck in sand/mud or baja mode.

You can run 4hi in wet/snow on the highway just fine, if you're on dry pavement you should only use 4hi if you're going straight so your uses in that case are limited.

what do you u mean uses? it's just a torsen diff, so nothing gets locked. i've been testing it in dry, with low speed and turns, no binding, everything seems to be working as a normal awd - that's what i was talking about earlier, 4hi is basically just awd mode.

You said you have a diff lock button, that's what I was referencing to using. Your torsen diff has a torque biasing ratio in it that is dependent on the gears inside it, how many of them there are and the helix they're cut at. You're not experiencing binding because when you have an open front and rear diff. You'll still get axle windup with a locked center diff when it's dry outside.

ohhh ok - yep. you were referring to 4hi in ur post so that's what i thought you meant. yes - will only lock center going forward in the wet/snow, i've never used it before

The regular F150's unlock the rear diff at 20mph, even if they're in 4wd. The Gen2 raptor doesn't when in one of the offroad modes. The gen1 raptor will unlock the rear diff like a regular f150 at 20mph, unless you have offroad mode on, then it stay's locked full time if you have have the switch pulled to lock it.
Some rock trails are a bit different than snow...lol. That looks like driver error, it slid off the trail it seems.
But yes, my raptor goes A LOT of places in 2wd with diff locked that Tacoma guys need 4wd for. Part of it is 35" tires, other part is Tacomas don't have a real rear locker.
Anybody here have a tilt back trailer? I'm looking to get a trailer this spring/summer and am heavily considering a tilt back as it'd be way easier to load the car without having a break over point.
Is it better to be going uphill the whole time? I use a winch, so wondering.
For a winch it doesn't matter if you're flat or on an incline. This kind of trailer just interests me because there's no break over point like you have with trailers that use ramps.
Is the breakover angle really much of a concern? If your car is low enough/ splitter sticks out enough you're going to need really long ramps to lessen the approach angle. And on that note longer ramps means your breakover angle will be less too. With a dovetail I suppose breakover angle will remain the same since its fixed but is that currently a challenge in your experience?
On the old dovetail setup I had I had to add 6' ramps in addition to the standard trailer ramps. The car wouldn't make it up with just the standard ramps and mucking around with 2 sets of ramps gets old fast.
This morning a friend showed me his Kwik Load rollback trailer and I'm going to go that route come spring time. No messing with ramps, no messing around with jacks or a hydro ram, lowest approach angle out there and available for under $6k.
Those are pretty slick, def a cool option and much better than what you linked above. I pondered this idea a few yrs ago and ended up with a standard 18' car hauler. I just use the ramps it comes with along with a set of race ramps and its worked out OK. Its kinda annoying doing the ramp shuffle but I got a pretty sweet deal on my setup so no regrets.
