When traction is lost at the rear wheels, the torque is biased to the front wheels. The torque to the front output shaft (3)
goes higher from the 38 percent, up to 100 percent torque. The torque at the rear output shaft (2) is lowered from the
62 percent, to as low as 0 percent torque.

that is great what you guys are typing but that isn't what i have seen in real life. not on a awd silverado or a typhoon or any other awd i have seen.

what i have seen is ONE front wheel spin faster than the rear is spining and one front wheel not spining at all but the average speed of the fronts closely match the rears.

I sorta agree with you about the wheel spin, one front tire will spin hard and the back probably is too. You can just hear the front one real good. I know what the literature say's as far as how the NVG-149 is supposed to work. The problem I have is that one front will spin, then the other tries to and the truck just wobbles side to side. Basically it doesn't feel woth a damn on a hard launch.

yeah i agree one tire does spin more than the other in front b ecause the pos diff is an unlimited slip lol.

heatign drag radials isnt the easiest thing to do on an awd truck , ill do a burnout and hope all goes well because throwing my belt was a common failure to running before .

how ever the next time out i will have drag radials/cal tracs and front straps. that better work or im going to kick rocks.

I definitely agree that two properly hooked rear tires is better than four unevenly powered tires for a host of reasons. The problem is that trucks aren't the greatest at dragstrip launches. Sticky tires go a long way in solving that problem but AWD makes it pretty much foolproof at or near factory power levels. It's as easy and point and shoot.

Just 4 link the rear and call it done...i think after you dial that in you prob are gonna end up ditching the front diff and t-case

thats the thing , i know a few have gone to 2wd but where is the fun in that? i want to be awd . ill keep it as long as i own the truck.

i just want it to be able to cut good lights,

4 link has definatly interested me but im not sure im ready to fab that all up yet. i think i will start a new topic on that.

I agree it would be cool to be different and have awd but when was the last time you saw a full on drag car with awd? most I have seen don't have problems cutting good lights.

you need to treat the truck as if it were a 2wd in the rear other than you need to match the front tires to the rear so that limits you some. the awd is great on the street and i of all people understand you wanting to keep it awd. i loved going out and racing in my truck and moping up on the streets. much faster cars would get behind a couple of cars right from the start and often not be able to make it up.
