Centramatic wheel balancers. These were on a 1987 F350 dually i had, I've had them on my 86 f350 as well. They work great, im just currently using balance beads in my tires and really like them. These should work on all ford/chevy/dodge 8 lug duallys from the 70s 80s and 90s. For more information please call or text Morgan at show contact info
thank you.
