Hey, thanks Longbox! I had previously put 6-degree caster shims under the front leaf springs, which turned out to be a big mistake. The stock suspension had only about an inch of upward travel before it hit the stop, so I decided to get some super-duper springs with the 1 3/4 inch width. So I ordered a set of Rubicon leaf springs, installed them, and ended up with the higher lift getting a couple of extra inches. I tried removing a leaf on each side, but that caused a 'sag' I didn't care for.
Hmmm, interesting comment about the 'High-Jacker' air-shocks. I thought the extra lift was their purpose. Another benefit ot a taller frontal height is that it could well accomodate a front solid drive-axle for 4 X 4 mode. Another reason for the higher rear height is that I installed a fuel tank behind the rear axle where the spare used to be and need a certain amount of clearance for it. Also, when I installed the power steering box, I decided to go to 'cross-steering' rather than face probable bump-steer with the shorter drag-link.
Regards,
