Harmonic Damper - SFI GM LT5 19-22

The Harmonic Damper - SFI GM LT5 19-22 is a precision-engineered component designed to safeguard high-output engines from the destructive effects of torsional vibration. Specifically developed for the demanding 2019-2022 General Motors LT5 platform, this balancer is an essential upgrade for builders seeking to maintain engine timing accuracy and component longevity. By neutralizing crank twist across the entire RPM range, it prevents the accelerated wear of bearings and timing sets that often occurs in modified performance vehicles.

Constructed from high-strength steel with a durable black oxide finish, this unit features a 7.750-inch outside diameter and is designed for internal balance applications. It meets the rigorous SFI 18.1 safety certification, ensuring it can withstand the extreme centrifugal forces and thermal stresses encountered in sanctioned racing environments. The viscous design allows the damper to remain effective regardless of modifications to the rotating assembly or power adders, providing a level of protection that standard rubber-based balancers cannot match.

Professional engine builders and racing teams will find the Harmonic Damper - SFI GM LT5 19-22 to be a vital addition to their powertrain specifications when pushing the limits of the ZR1 platform. Installation of this balancer is straightforward for those familiar with GM small block architecture, offering a direct fit for the 2019 through 2022 model years. Whether you are conducting a full engine build or looking to buy a reliable replacement for a factory unit, this damper ensures your high-performance LT5 operates with maximum efficiency and safety.
