Making 22s fit on already bagged chevy

I have a 2000 chevy crew cab dually that lays frame with 16's which originally is what it was setup for. Now I wanna upgrade to 22's. What is the best way to make this happen ? New control arms , notch the frame in the front for more turning space ? Do I need to tub the firewall ?What kind of adapters do I need for the rear to bolt up and not change anything but widening the fenders ??

when i did my 2000 i had orginally built it for 16's as well... I didnt do anything different to the front at all.. it already had spindles on it so only thing i did was build tubs for it not work at all on mine. as far as the rear it was two linked with pan hard bar and the only thing i had to do was move the bags inward alittle... (was running 16 for inside wheel) so my swap was easy except for stretchng the fenders...... good luck....



went from those wheels to 22 pretty easy ..
