Description

This ATI-built damper controls harmful crankshaft vibration and delivers consistent belt drive operation. Built around a 6.78-inch diameter with an aluminum construction, the 6-groove, 4-ring layout is engineered for Mustang applications that utilize the OEM 31-tooth, 8 mm HTD interface. The design helps protect the crank and anings, promotes clean belt tracking at elevated RPM, and offers reliable performance for enthusiast builds. Precision machining and balanced assembly support durability without unnecessary weight. Please verify pulley alignment and belt/drive compatibility for your specific setup before ordering.
