7700 Package
i have an 01 7700 and the only black wheels ive come across so far are the Rockstars. But there would be no benifit what so ever for you to switch to a 10.25 unless you plan on towing alot of heavy loads, even then th 9.75 is the more than capable. As far as keeping the 8.8 with 37" or bigger tires, i dont think you would have any problems unless your putting i through some heavy abuse, then your axles will be the weak point.
and im not a fan of the rockstars, too many people have them
7 lugs
One thing to remember is that the 97-04 Heritage has a different offset than the 04 NBS and up. Found that out while researching getting new rims for an 07 7 lug truck I have. I think I found the ones I'll ultimately get to replace the Eagles currently on my truck.
Good luck on your trucking
Paul
