Performance accessories body lift for like $260. #inches and wont mess up you suspension. Do NOT buy that 5 inch kit. Its junk. Check out Dakotausa.com. These guys know Dak and arent a bunch of A-holes. The 3 inch Rancho kit is the only suspension kit worth buying.
I did the 3 inch body lift on my girfriends Dak. I also got 3 inch add a leafs and cranked the torsion bars and this allowed clearence for 33's. The truck Rides WAY better than stock now too. Total lift cost was around $300 and the a grand for tires and wheels. heres a pic or two. The second one is next to a stock Dakota that I am actually building for a buddy the same way.
