ok, so I've never done a 4wd start before. after you start and get up to 30-40mph, do you shift back to 2wd mode? is it harder on the transmission? thanks guys.

 

of course a 4x4 boosted launch is harder on the tranny your getting another axle spinning with more weight on it

 

ive always kept mine in 4wd when i go down the track, it is kinda hard to shift out of 4wd when ur wot

 

thats why i got the 2low setup on my 12v so when im going down the strip i can flip the switch and it will disconect my hubs, it wont stock my t-case from spinning but it will reliese the drag and pressure of the front tires

 

thats a pretty slick set up

 

just a pacbrake switch on a toggle that controlls the vacuum for the hub 4x4 actuator

 

if its standard i just push the clutch in for a sec to release pressure and put it back in 2wd...."94cummins12v" has a nice setup tho to

 

i think that would drop you time doing that

 

yeah, rowing gears is bad enough for times

 

that actuator switch i hav is just on a toggle switch, i have it set upso when im at the track i can mount it on my steering wheel for easy activation
