I have 3 inch lower blocks but would like it to be about 3 inch lower yet. Has anyone every moved the rear spring holders up into the frame. I know I would have to box it out and re-enforce the area but it looks like I could gain about 3" Would this cause and unforeseen problems.

Working only 32 hours so I don't want to put any money into re-arch springs. I never thought about the Pinion angle. I guess since the back of the spring goes up higher the pinion angle would change. I would have to move both front and back to keep the same angle. I going to have to re-think this one out. I get one of my sons to trig this out.

We just removed middle springs and ran the top on the shackles and small bottom overload. We did not haul anything but a Igloo cooler of beer and road real nice. I put traction bars on it so I would not twist the rear out when I stomped on it, but it had 24" wide Hoosiers on it. If I remember right, I put the rear on top of the 2 springs and that was enough to get it down. This mod required the frame mods you talk about as well.
