Product Description
The BILT 2 PERFORM GM Gen III/IV LS Harmonic Balancer and Bolt Kit combines a high-performance harmonic balancer/damper with the installation hardware needed for compatible GM LS applications. Designed for Gen III and Gen IV LS truck engines and Gen IV LS car engines, this package provides a coordinated solution for replacing or upgrading the factory harmonic balancer assembly.
The included high-performance harmonic balancer/damper features 4- and 6-groove pulley provisions for compatible accessory-drive configurations. A Pro Series harmonic balancer/damper bolt kit is also included, providing the required fastening hardware for installation. By combining the balancer and bolt kit into one package, BILT 2 PERFORM eliminates the need to source these components separately.
Ideal for LS engine builds, rebuilds, swaps, and accessory-drive upgrades, this kit provides a convenient harmonic balancer solution for compatible GM Gen III and Gen IV LS-series V8 engines.
