LS Harmonic Balancer Pul ley Install Tool LS1

The ICT Billet LS Harmonic Balancer Pulley Install Tool (part number 551141) is a precision engine service tool engineered specifically for GM LS-series and GenV LT-series engine platforms. This specialized installation tool simplifies the critical task of harmonic balancer removal and installation, featuring a 16 mm x 2.00 thread design that interfaces directly with factory LS and LT harmonic balancer specifications.

Harmonic balancer installation demands precision and proper tooling to avoid damage to the crankshaft nose and bolt threads. This tool's threaded design allows controlled, straight-line engagement with the balancer without wobble or misalignment—critical when working on freshly rebuilt or high-performance LS engines where balancer indexing and runout specifications are non-negotiable. The compact dimensions (3.1 x 0.9 x 8.5 inches) and lightweight construction (0.77 lbs) make it practical for both stationary engine work and field-portable applications. ICT Billet's reputation in LS engine accessory manufacturing ensures this tool meets the fit and function standards that engine builders and technicians expect.

This tool addresses a specific pain point in LS and LT engine assembly and service: achieving proper balancer seating without risk of cross-threading or crank damage. Whether rebuilding an LS1 engine, swapping a crate motor, or servicing timing components, technicians and builders who work on GM's fifth and sixth generation small-block architectures will recognize the value of purpose-built tooling over improvised methods. The 16 mm x 2.00 specification is OEM-correct for both LS-series platforms and the newer GenV LT lineup, making this a single tool solution across multiple engine generations.
