The pirate thread went off the rails early for some reason. Not every 4x4 is for climbing boulders at 80 mph.......
So anyways.
Do you have a wheel travel # you are aiming for?
I know - as much as possible - is always good, but is there a specific uptravel and droop # you need for the SAR trails? I've been on some of the pedestrian climbing trails, fitting an actual road vehicle up one of those is no mean feat.
You've probably already done it, but what happens if you graph out your 96" wheelbase, center the transfercase, and work out the geometry angles on the driveline to see what your maximum wheel travel would be?
Then just link it as close to the center (transfercase yokes) as possible, and run bumpstops and limiting straps to keep the driveshafts alive?
I'm probably being overly simplistic.....but that's my offroad butt dyno idea-maker at work.
I really really liked this fellows use of a narrowed C3 Corvette rear IRS in his CJ2A. Dual purpose rig (road, rock, sand - is that still dual-purpose?) when I asked him what made him decide to run the IRS the answer was simple. "it eliminates the too-short rear driveline issues as the 3rd member is in a fixed location, travel is what it is."
Beautiful. Adjust the driver (or learn to drive the vehicle) and enjoy the ride.
I don't think it is widely realized that factory linked fronts and rears have been in use for decades in multiple vehicles.
