Harmonic Balancer Instl. /Puller GM LS Engine

The Harmonic Balancer Installation and Removal Tool for GM LS Engine by PROFORM is an essential specialty tool designed for serious LS engine builders, mechanics, and performance enthusiasts who need reliable access to harmonic balancer work. Whether you're performing routine maintenance, upgrading ignition timing components, or rebuilding a high-performance LS platform, this dedicated kit eliminates guesswork and damage risk during one of the most critical crankshaft-end operations. Harmonic balancers are precision-balanced components that absorb torsional vibration; improper installation or removal can compromise engine balance and cause catastrophic damage, making the right tool non-negotiable.

This installation and removal tool features multiple precision-engineered adapters that match the specific bore and threading patterns of LS-series harmonic balancers, ensuring zero runout and proper seating during installation. The steel construction provides the rigidity and durability required for repeated use without flexing or stripping fastener heads, while the included storage case keeps all adapters organized and protected in your shop. PROFORM's engineering ensures each adapter interface aligns concentrically with the crankshaft nose, preventing the harmonic balancer wobble and premature wear that results from hand-tool installation or improper pullers.

Professional technicians working on LS1, LS2, LS3, LS7, and other LS-family engines will find this kit indispensable for both new-build and retrofit scenarios—from mild street engines to race-prepped platforms. The compact footprint and comprehensive adapter coverage make it ideal for engine shops, performance builders, and dedicated hobbyists who run multiple LS-powered vehicles. Weighing just 6.43 pounds and dimensioned for easy workbench storage, this tool delivers professional-grade results without the expense or space burden of industrial equipment.
