Racing in 4 wheel drive?

[T.R.P.]

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?

[PGreenSVT]

Well I tried it at the drag strip Fri. night and my truck seems none the worse for the wear.

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.
