Whether you race at the track or rack up miles on the street, ATI harmonic balancers are the perfect choice to dampen harmful engine harmonics. These durable dampers are a cure for many LS and LT based applications where the OEM balancer shells are known to come loose from the hub with age, and also provide additional engine protection for higher RPM performance and racing builds.
