have a site that is more for the Grand Cherokee's, or can someone help out with some links for Air intake and Exhaust performance, and maybe something with a supercharger?

If it's a 4.0L grand, the same things that work on a 91+ XJ 4.0L work on a grand too.
you can also look into dodge trucks for performance options for the 5.2/5.9 (something to broaden your information horizons)
I dunno of the 4.7 was used in anything else, but I'm sure that it was/is

Those GCs that have D44s from the factory have Aluminum center sections.

People complain that it's got C clips... The same people running around with D35's with C clips. Pretty funny.
From the reputable sources I've been talking to the ALD44 is stronger than the D35c but not as strong as the D44. Overall, it's better but not best!

This is HIGHLY debatable.
Around 1999 DC actually threatened to cancle ALL Dana-Spicer's contracts and bring in another company to make axles, all because of problems with the aluminum D44 that DC had demanded. The housings are so weak that several shipments of them bent on the storage racks at the factory just from their own weight.
The 1999 WJ FSM tells you not to jack the rear of the vehicle with a single floor jack under the diff, because the weight on the ends of the tubes will warp the center housing.
Better than a D35? I disagree. That aluminum D44 imposter is a far bigger POS than the D35 could ever hope to be. Been there, done that, got the tee shirt.
