Question for those who launch in 4-hi

Thats because its not Automatic 4x4. Its basically AWD. It has clutches that vary the torque to the front up to 50% on the fly, so the truck can launch 50:50, 40:60, 30:70 etc. Whatever it feels is best. Power always goes to the front wheels in 4A(or almost always. in the right conditions, like cruising at 65mph perfectly straight, it may send it to the rear only.)
