I have a 3" MAF lift, and when fully loaded the rear squats too much. So I installed the short add-a-leafs. No more full load issues. Ride sucked though. Found out that OME makes a long add-a-leaf (thanks David Dearborn for the tip!) Just finished removing the shorties and installing the OME's...huge improvement. Ride is much better. Will have to see how it loads up, but I'm sure it's better than with the original springpack. Anybody want some short add-a-leafs?
