I have a 1995 Buick riviera with a 3.8lv6
supercharged what weight 1lb or2lb weight
harmonic balancer is supposed to be on
They used both the 1" weight and the 2 1/2" weight in 1995. You may have to take the VIN number and the production date to a Buick dealer and see if they can tell you which one belongs on the car.
