Drag racing a 6 speed in 4wd

[6LiterGearBeater]

I was just curious as to how the truck would handle the shock of the shifts. I know the front and rear end and transmission are tough as nails, but I'm curious if there were smaller things that could brake, like the factory hubs? Could the transfer case handle it?

Yeah im curious bout that to. Im scared to death to launch mine just for the simple fact that with the auto you already have to preassure on the front end when you launch but with the sticks all that pressure hits at once. Looks to be like it would mess up the hubs or destroy u joints.

Coming from the off-road world and a stick..... You are more prone to breaking Teeth off the R&P's b/c of the shock load. Autos are nicer to R&P's. If you do dump it, make sure the front wheels are dead straight, no turned wheels. So if you dumped it, and you didn't break the R&P yet, then you gotta worry about the front axle shaft U joints. Not sure how strong the D60's are, but they are strong. I'd worry more about them than the driveshaft U joints...

not to sound like a jerk but all WHAT pressure ??
with an auto we are launching at FULL BOOST and leaving FOUR black streaks in the pavement, you will not be leaving the line with nearly the same force in your handshaker.

and yes, the transfer case is SOLID, you will not break it ! ! ! !

Your stock clutch will cry uncle first before anything else breaks!

Just talk to Ditty, LOL.

Yea the stock clutch will be the first thing to go. The time I did a 4dr launch I went no where. It gave up instently. Now I have a South Bend clutch and am having no problems.

i've done 4x4 launches with the stock clutch and never really had a problem.

LvTitan, I think what he means is that everything is already loaded in the auto(trans, driveshaft, gears, etc.), whereas when the clutch is dumped, everything is loose, then gets slammed when the clutch is dumped.

yes i see, but remember with a manual tranny you are dropping the clutch and loading up the driveline BEFORE you are making a lot of power. once the engine loads up and starts boosting you are way past the moment of side step.

on an auto, we are leaving the line instantly with all 500+ HP and 800+ torque transferring to the pavement instantly. you tell me which luanch is gonna be harder on the drivetrain ??

i see what you are saying though, we are not "shocking" the drivetrain becuase it is already taking the slack out of everything while we are spooling it up.. good point.
