Question Racing in 4 wheel drive?

What are the disadvantages of this?

Some say its hard on the transmission, BUT, it ain't no worse than taking the truck off road.

You get on a sticky sarting line boost youre truck and launch in 4x4. You cant be much harder on the driveline than that.

I suppose.

I did it once to see what it was like from like 2100 rpm. IT felt great, but that guilty feeling over came me.

I can usually get away with launching at 1800 on the street without spinning in 2wd. I may be able to get away with 2000 at the track without spinning in 2wd.

I have always been told that you need some slippage when in 4WD and not to run that way on the street or it will bind up the transfer case. I have experienced difficulty with a manual transfer case getting it to shift out of 4WD after just a few hundred feet on pavement. I can't imagine that launching and racing in 4WD on pavement is very healthy for your truck.

do you need the slippage if you are traveling in a strait line?

How do you switch out of 4X4 going down the road? Just put the manual 4x4 shifter in neutral as you are going?

Mines not manual. I just reached up to the dash and flipped it back to 2x4 on the return road.
