gabbett1 Posted March 14, 2005 Report Share Posted March 14, 2005 Any of you guys running big horsepower (i'm talking about the guys that are running low 12's or better) ever made any changes to your all wheel drive system? My machanic told me that I wouldn't be able to do much more power to my truck with out changing some of that stuff. I'm running an 8psi Pro Charger system and just recently put in my shift kit from Zippy. Quote Link to comment Share on other sites More sharing options...
