add-a-leaf question

[250-highboy-76]

I have a 76 F-250 highboy and was wondering if anyone has tried the front and rear add-a-leaf. I have a 6 spring pack up front with a 9 spring pack in the rear how much will this actually raise it and is there a prefered brand?

Don't waste you time with an aftermarket add-a-leaf have a truck spring shop add a leaf and re-arch the springs. They replace the eye-bushing, etc., etc. and the springs are like new with around 2 to 3" of lift depending on how bad they had sagged. The problem is that they ride harsher after they have been re-arched.
