Overview 

The LS Crank Pulley Installer Harmonic Balancer Tool is a precision-engineered tool designed for safely and efficiently installing the harmonic balancer onto GM LS-series engines, including LS1, LS2, LS3, and LS6. Constructed from high-strength steel, this tool threads into the crankshaft snout and uses a thrust-bearing-equipped press bolt to smoothly and accurately draw the balancer into position without damaging threads or components. It eliminates the need for makeshift or hammer-based methods, making it a reliable solution for both professional mechanics and DIY enthusiasts working on LS engine builds or replacements.
