For as long as QD has been around, I believe it was only available early on with the 4.0L I6 and those are very rare. After a year or two they changed it to only be available with the V8 and now the diesel.
I find that to be kind of funny... my 3.6L V6 has about 50 more HP than the 4.7L V8 in my 02 GC. But the 4.7L had 295 ft-lbs of torque compared to the 3.6L's 262 ft-lbs, so that may be the issue. Or it could also be related to the different transmissions being used between the gas V6 and the diesel / V8.
QDII is not the same today as it was on my 02. The 02 had Vari-Lok front and rear axles that used gerotor pumps along with one in the transfer case. It could send 100% engine power to any of the 4 wheels. That was the best 4WD system I've ever had, and I've had plenty over the years.
