re 8 s for 3500?

will the slam re8s be the best choice to bag the nose of a 3500 chevy dually with a 454 or do 7s? or contitech 2600s

i have a 2000 chevy with the 454 and i have the slam re8's on my dually and have not had any problems with them you just need to trim out a lil of the uper frame to make sure it clears and your spacing is right... if you lift to high the brake calpier nut that connects to the bleeder line tends to want to rub... other than that i have had no problems...
