i have a 1991 F-250 4x4 with the 7.3 diesel. The leafs in the front are worn out and i was wanting to know if i replaced them with 2" lift springs would it level the truck out or make the front end ride higher than the back. I plow with this truck so i was also wandering if the 2" leafs would handle the weight of the plow better. I have a buddy that has extra stock leafs and the 2" leafs that i can chose from. Any suggestions will be greatly appreciated.
