Wheel Spacers?

[Big_Block]

Does anybody know if any companys make some kind of wheel spacer on your axles to make your wheel sit out more on teh axle and not tucked in so close? like is there a way to put a spacer of somekind behind the wheel on teh axle and just extend the wheels studs, cause i just got new wheels for my truck but they sit in the wheel well way to much for my liking and I was just wondering if i could get away from that by doing somehting simple by putting a spacer of some kinda in there..if anyone has done this or has any other ideas that will work for this would be greatly appreciated, thanks!
