I have an 1989 d250 diesel 2wd and i would like to raise the my truck up 2-3". i know how to raise the back by using blocks. but i dont know how to raise the front. i Have d350 severe heavy duty springs in the front so the truck doesnt sag at all in the front i just want some more clearance. i also have heavy duty shocks to help. the truck is level but i just want to be able to get some more clearance instead having the wheel in the wheel well. How can i raise it up?

Thanks
