I need to raise truck bed 3 " to clear frame hump in my 40 Chevy truck.looking for some how to or possibly some pictures . Thanks Larry
well, you did ask about raising the bed to clear the hump, not raising the bed floor
i'm gonna go out on a limb and say this is for a C-notch "hump", since it's a stepside, it's very easy to raise the floor. just weld in 1.25" angle iron 3" up on the bed sides and raise the rest of the structure with pressure treated wood. i'm more familiar with chevy beds than ford beds, but i assume they are similar in that the bed wood supports the bed.
this is a fleetside bed, but the support is the same, angle welded higher and blocks under the bed sills. you end up with a goofy filler when the tailgate is down
you can also just raise the bed section over the axle, i'm finding fleet beds only
