6.4" SB Ford 5.0L 50 oz. 1980 & Later Harmonic Race Damper

Ford SB 1981 6.4 Harmonic Balancer. Our SB Ford Dampers have more universal features than any other damper. All SB Ford models are made to the early short length. This allows the use of a late 5.0L engine with a 50 oz. in. damper to be used in an early chassis where front clearance is at a minimum. To fit in late vehicles, we offer a series of spacers to provide the correct front pulley alignment. These Ford dampers also have three sets of timing marks and both 3 and 4-bolt accessory pulley bolt patterns. The supplied plastic insert can be used to center 3-bolt pulleys with a female pilot, or it can be removed to accept 3-bolt pulleys with a male pilot. These dampers are very versatile and can be used on many different Ford engines.
