If I change from the Ford OEM Balancer to the ATI Balancer I will have to change the belt to a shorter belt, correct?
ATI being 6.78" and Ford being 7.5"
The stock damper from my 2010 GT is roughly 6 3/4” where the belt rides and I replaced it with an ATI 6.78 damper. It will take the same belt your using now. The 7.5” measurement is the heavy part of the damper in front of the belt.
