I was trying to find the post that listed the spring codes. I remember it listed the front and rear with part numbers and load ratings. If i remember correctly The F250 has a 6200# rear spring.
The F350 has a 6800# rear spring
The F350 dually has a 8200# spring in the rear
Also the F250 has a 2" rear block versus a 4" rear block.
And both are avaliable with teh camper package ( rear overloads)
