OEMTOOLS Harmonic Balancer Puller Kit for GM 3.3L/3.8L V6 — Heat‑Treated, Floating Swivel, Includes Metric & SAE Bolts

The OEMTOOLS 27187 Harmonic Balancer Puller Kit is a complete, heat-treated toolset for safely removing harmonic balancers, dampers, pulleys, and gears, including bolts to fit GM 3300 and 3800 V6 engines.

Whether you’re a professional technician or a home mechanic, the OEMTOOLS 27187 kit provides a compact, durable solution for extracting crankshaft pulleys and vibration dampers without damaging shaft ends. The kit’s floating swivel design and heat-treated components reduce the risk of slippage and breakage during removal, while the included bolts and adapters cover the common fitments on GM 3.3L and 3.8L V6 engines. Packaged in a blow-molded case, the set stays organized and ready for the next job.

How does this puller protect the crankshaft during removal?

The kit uses a floating swivel center that self-aligns with the crankshaft end, distributing force evenly and minimizing side-loading. That design helps prevent scoring or bending the shaft when extracting stuck balancers or pulleys.

• Floating swivel center reduces lateral force on the shaft.
• Heat-treated bolts resist bending under torque.
• Threaded arms and adapters align the puller concentrically.

What engine applications and fasteners are included?

OEMTOOLS 27187 ships with a selection of metric and SAE bolts and specific fasteners tailored for GM 3300 and 3800 V6 engines, so you won’t need to improvise or source specialty hardware for those common GM applications. The kit also works on many other vehicles with compatible pulley and damper configurations.

• Bolts sized for GM 3.3L and 3.8L V6 harmonic balancers.
• Universal puller arms and crossbar for varied pulley sizes.
• Adapters to accept different thread pitches and depths.

How durable and reliable are the components for workshop use?

Every major piece in the set is heat-treated to increase strength and resist deformation under load, delivering consistent performance across repeated jobs. The rugged metal construction and quality threads mean the toolset stands up to professional use and heavy DIY tasks alike.

• Heat-treated steel parts for higher tensile strength.
• Precision-cut threads to prevent stripping during removal.
• Lifetime-ready design for frequent garage or shop operations.

Which tasks can this kit handle around the garage?

Beyond harmonic balancers, this puller kit removes vibration dampers, power steering pulleys, and other press-fit gears and pulleys. It’s versatile enough to tackle seized components that would otherwise require more invasive disassembly.

• Removes crankshaft harmonic balancers and dampers.
• Pulls power steering and alternator pulleys when applicable.
• Extracts press-fit gears and small timing components on compatible shafts.

Who is this for: The OEMTOOLS 27187 is aimed at professional mechanics, fleet maintenance shops, and committed DIYers who work on GM 3.3L/3.8L V6 engines or need a reliable, multi-purpose pulley puller. If you value a compact, heat-treated toolset that keeps common fasteners and adapters organized in a sturdy case, this kit will streamline pulley and balancer removal jobs and reduce the chance of damaging engine shafts.
