Slam bags are known for not expanding width wise as much as others by a long shot in some cases. And usually get more lift.
You say you get a lot fo lift, but does it lay and get a lot of lift? You can lift the frame 12" off the ground, but only be getting 8 inches of lift, you know.
And also, you should have welded the lower bag mounts in first, in the back, so that the bags are botomed out completely when laid out, because go dknows you need as much lift in th back at a 1:1 ratio. You'll get 5" lift total.
