I have been searching all morning for old posts on this and haven't found one that had a solution. I have a 92 D-350 and with a rebuilt front end and new springs the front end is just taller than the rear without a load. I would like to increase the rear ride heigth for looks when unloaded and to keep the nose down when towing. I have a pretty substantial trailer I tow and I really need to keep and/or increase rear load capacity. I have considered adding maybe two inch blocks and airbags. I would really like to hear from someone who has solved this problem and can relay their experiences. If money was no object I would just go to full rear air-ride! But, that's not an option now. Thanks guys!
