Woosphy Harmonic Balancer Puller for GM LS Engines 25264 — Heavy‑Duty Single‑Unit

Woosphy 25264 is a heavy-duty harmonic balancer puller engineered to remove LS-series crank pulleys quickly and safely without damaging the crank snout or pulley face.

If you're servicing GM LS engines — including 5.3L, 5.7L (LS1), 6.0L (LS2), 6.2L (LS3) and 7.0L variants — this puller gives a precise mechanical advantage to extract the harmonic balancer. Built as a straightforward replacement tool for OE number 25264, it arrives as a single complete unit ready to install on compatible engines. The design prioritizes tool strength, alignment, and repeatable engagement to reduce the risk of slippage or cosmetic harm to components while working in tight engine bays.

How does the Woosphy puller remove stubborn crank pulleys?

The tool uses a center-forcing bolt that pushes against the crank snout while drawing the balancer off its taper. Controlled, straight-line extraction avoids twisting or levering that can mar the pulley, keyway, or crank. The robust construction transfers force evenly for smooth pullover action.

• Center bolt applies axial force to remove press-fit balancers.
• Threaded engagement secures puller to balancer for stable extraction.
• Precision alignment reduces side loads that cause damage.

Will this fit my GM LS engine model?

Woosphy 25264 is specified to replace OE part number 25264 and is compatible with many common LS motors. Confirm fit by matching your vehicle’s engine designation — the puller supports several LS family displacements used in GM platforms. Always check vehicle service literature or parts diagrams if you have an uncommon variant.

• Compatible with 5.3L and 5.7L (LS1) engines.
• Works with 6.0L (LS2) and 6.2L (LS3) models.
• Also suitable for 7.0L LS applications that use the OE 25264 interface.

What comes in the package and how is the tool built?

The product ships as one assembled harmonic balancer / crank pulley puller ready for immediate use. Materials and machining provide consistent threads and a hardened contact surface for the center bolt. The kit is minimal by design — no extra adapters unless your application requires them — making it a straightforward replacement for the OE tool.

• Includes: 1x harmonic balancer puller (complete unit).
• Manufactured with durable, machined components for longevity.
• Simple, single-piece packaging for quick deployment in the shop.

How should I use the puller safely to avoid component damage?

Position the puller square to the balancer, engage the threads fully, and turn the center bolt steadily using the correct socket and breaker bar. Do not use impact guns on the center bolt unless specified by an expert — slow, controlled torque prevents sudden releases that can harm nearby parts. Wear eye protection and follow standard shop safety practices when working under the hood.

• Ensure centered alignment before applying extraction force.
• Use steady, even torque on the center bolt; avoid sudden impacts.
• Inspect threads and mating surfaces for cleanliness prior to use.

Who is this for: The Woosphy 25264 puller is aimed at professional mechanics, experienced DIY enthusiasts, and automotive shops that frequently service GM LS engines and require a reliable OE-number replacement tool. If you work on 5.3L, 5.7L (LS1), 6.0L (LS2), 6.2L (LS3), or 7.0L engines and need a durable, easy-to-use harmonic balancer remover, this tool simplifies pulley removal while protecting engine components.
