what are some easy ways l can increase my torque on my 02 v6 3.9 dodge dakota..

Well it is really not easy but you could get some shorter gear is like 4.56's. It will hurt your gas mileage on the highway really bad though. Another option that really is not that easier either is installing long tube headers for it. That will give you some bottom end. To tell you the truth, it is going to be really hard to give you bottom end power without spending some money. Good luck.
