Is it okay to use 2wd low when offroad?

I have spent the last week running my Dana 20 TC in (what seems to be 2wd low). Although not marked on the shifter, I am able to utilize the lower gearing by shifting my TC between "N" and "4L" without engaging my hubs. It is not the same engagement as pulling the shifter all the way down to "4L" and I am assuming it is okay to run it without locking the hubs. Am I gonna burn something up? I did not need 4wd, but did need the lower gearing thanks to the tall 1st gear in the t-150 3spd. Thanks

I'm interested in this as well, mine has no labeling for 2Lo , it goes 4H 2H N 4L but i have 2 distinct positions after N, both engage low range gears. I have the dana 20 as well.

Absolutely use it if you need it. Just be careful with the throttle as you're sending 2x the torque to just the rear axle.

No problem with leaving it in 4low and the front hubs unlocked.

sometimes i need a little help thru a gully or, like another posted, to move a trailer around. So 2low w/ the rear ARB engaged = fast, easy traction. then kill ARB and go back to 2 hi.

Twin stick the 20, and the leave the front in neutral and rear in low.
When wheeling, you don;t want to be out locking hubs every 20 seconds.
It'll also allow to to unlock a locked front for better turning and unlock the rear for front digs etc...

I often shift into '2 wheel low' just to make mine steer better on trails when I don't want much speed...
You can make it an 'Official' detent in the linkage if you ever rebuild simply by grinding/drilling the selector arms when they are out of the case.

Nothing 'Wrong' with it, but if you hit something that makes the jeep jump, you may wind up in Neutral ... That's the only draw back.

It won't hurt anything in the case or your drivetrain if that is what you are asking...

x2 on JH's post-- sometimes i need low range traction for just a minute-- and rather than get out to twist the hubs, i just drop the single stick D300 into low range, hit the rear locker and its good to go.

wheel-on brothers!

thanks for the feedback, nice to know I wasnt destroying something else! I am curious about the mention of the twin sticking, is there an existing string to address this or details available?

This is what you have already with the shifter in the "ghost" 2Lo position.

It's the result of slop in the tcase linkage that allows the rear output shifter rod to engage low range before the front output shifter rod has moved out of neutral. If there wasn't slop in the linkage both rods would leave neutral and engage low at the same time. That's why it isn't marked on the shift knob as it wasn't intended to be there.

The twin stick mod allows you to control the front axle and rear axle independently of each other. Check out JB fabrication, they make a nice stainless twin stick set up. It's a bolt on deal and very easy and useful.
if you look at the dana 20, you'll see 2 shift rails. The stock shifter controls both of them at the same time. The twin stick puts a lever for each shift rail, so you can have independent control.
IMO a must for every xfer case, especially when you have a front locker.

Using lo in two wheel drive is a common tactic for owners with three speed transmissions. Before my tranny swap I used it constantly on such things a steep boat ramps, ,moving trailers around the property, fence repairs, etc... If your not in need of the front axle at all, simply drop the t case in 4 low and you won't have to monkey around finding the "sweet spot". While twin sticking is good for the hard rock crawler with a locker in front, it probably isn't necessary for the average wheeler and the cost in time and money to install it may not pay off.
