So my one brother put some 6in lift springs on the front of his 95 f350 cc. My other brother has a 97 f250 sc 460 and put his old springs on. Rides better but after looking at them more it looks like the springs are smaller. /ubbthreads/images/graemlins/shrug.gif Sure enough I climb under my truck and and they look way bigger than the f350 springs. Anyone know why?

Cause the 250 springs with the TTB have to have a lot higher spring rate because each side of the axle has to be able to support basically 2/3 of the front weight when it hits a bump versus the weight being split evenly between both springs on a 350 with a solid axle.
