how would a 2wd suv with a arb air locker compare to a regular 4x4 without a locker or ltd slip ? i figured it might be predy close becasue 4x4 is realy only 2wd in a way ( one front one rear) but a air locker would drive both in the rear. thanks for the input

 

Well it'll help lay down traction, thats for sure. It depends on what you want to do. Offroad? Baja? Sweet donuts? mmmmm donuts....

 

not much sorry it's just not the same as having just one wheel in front and one in back!

 

Depends.........

on the situation.....

 

How about on sand?

 

If the and is soft enough, I know my LT will dig in and get stuck. momentum and low psi in tires was I learned.

fully locked axle is better than a 1 wheel peel in the sand.

 

Maybe a little better maybe.
Typically a 4x4 has open differentials. That means if one tire loses traction, all the power on that axle goes to the tire with no traction. One tire spins and the other does nothing. On a 2wdr truck, your stuck. On a 4x4 you still have at least one tire on the opposite axle with traction. Now if you lock the drive axle on a 2wdr truck, you in essence have the same number of tires with power as an open diferentail 4x4. There are situations when a 4x4 will go places a locked 2wdr cannot, and there are places a locked 2wdr can go that a open 4x4 cannot. Climbing hills the 4x4 will have the advantage. If one tire on each axle loses traction, commonly called crossed up, then the locked 2wdr will have the advantage. There are instances in sand where either rig will have the advantage. Its pretty easy to get crossed up in the sand, and its also just as easy to lose traction to the whole alxe in the sand.

Knowing how to drive your truck will get you through. Most off-road driveing is 80% driver and 20% rig.

Now there are some tips to help you have more fun and go more places. Since you mentioned the sand, we will stick with that. Momentuem will be your friend. Let the speed of the rig carry you over the soft spots. Only stop on solid ground. Never stop in the loose sand, you will dig a hole to china faster then you will get unstuck by yourself. Which brings up what to do once your stuck, in a locked 2wdr. Call for a tow strap before you need to shovel your tires out. If oyur in a 4x4 lightly apply the brakes, it will mkae all tires spin and hopefully gt you out. If not, call for the strap.

Air down. Drop your tire pressure to 15-20psi. This gives you a bigger footprint, and the tire will do much better floating on top of hte sand. I also prefer all-terrain tires over mud tires in the sand. Mud tires are designed to dig, you dont want to dig in the sand. The tire that has dominated the last 20 years of Baja racing is the BFG All-Terrian tire. No other tire comes close to the number of wins the BFG KO has, anywhere.
