I got 4 inches of lift on a 3/4 ton so it must be a hair more.
Hate to brake it to you but 3/4 and 1 ton springs are the SAME THING. So you either didnt have 3/4 springs in your truck or you didnt put 1 ton springs in.
The only difference between the rear suspension of a f250 and F350 is the 2.5" block on a F250 and 4" block on a f350. Both a 5 leaf springs
THAT IS IT. NOTHING ELSE
And to the OP, unless you want to add weight carrying capacity to your F150 you would be foolish to put 350 spring in. Ditch you F150 block(2") and put in a F350 block(4")
