umm yeah stock transfer case and stock trans. boost launching?? is that safe to launch the truck in 4 high with all stock internals... im not trying to spray front end and tranny parts all over track lol

 

your gonna if you launch in 4wd. very light 4wd launches if that. your still gonna have to upgrade

 

You should be safe to about 8-10 lbs. with the mods in your signature. I use to run about 8 on a stock tranny with the transgo shift kit and crazy larry at the dragstrip. The weak link in the trans is the input shaft. The stock transfer case is plenty strong enough even with a built tranny, then the billet shafts in the tranny are still weaker than the transfer case.
