OEMTOOLS GM harmonic balancer puller for LS engines — clip-in crank pulley puller, fits 5.3L–6.2L with adapters

The OEMTOOLS 25264 GM Harmonic Balancer Puller is a clip-in crank pulley puller built to extract harmonic balancers quickly from GM LS and select Chrysler/Jeep/Dodge engines without removing the radiator.

This specialized puller is engineered for faster harmonic balancer removal on popular engines such as GM 5.3L, 5.7L LS1, 6.0L LS2, and 6.2L LS3, plus Chrysler/Jeep/Dodge 3.5L V6, 4.7L V8, and 6.1L V8. Constructed from high-strength materials and supplied with multiple bolts and adapters, it fits applications that lack tapped holes and reduces teardown time. The ergonomic design and clip-in attachment simplify alignment and operation, making the task less awkward in tight engine bays.

How does this puller remove balancers without tapped holes?

The OEMTOOLS 25264 uses a clip-in retention system and assorted adapter bolts to engage the crank pulley from behind, so you don’t need factory-threaded holes. That approach lets you apply steady pulling force while keeping the radiator and surrounding components in place on many vehicles.

• Clip-in adapter secures to pulley lip or recess for non-tapped applications.
• Assorted bolt sizes adapt to different crankshaft boss diameters.
• Central forcing screw provides controlled, even extraction force.

Which engines and vehicles will this puller work on?

This tool covers a broad range of GM LS-family motors and a selection of Chrysler/Jeep/Dodge V6 and V8 engines commonly serviced in garages and home shops. It’s specifically useful on models where the original balancer lacks accessible threaded holes.

• GM compatibility: 5.3L, 5.7L LS1, 6.0L LS2, 6.2L LS3 and other LS-family variants.
• Chrysler/Jeep/Dodge compatibility: 3.5L V6, 4.7L V8, 6.1L V8, and related engines.
• Useful for Silverado and other trucks with press-fit harmonic balancers.

What makes this puller durable and easy to use?

OEMTOOLS designed the 25264 from high-strength steel components and a robust forcing screw to withstand repeated shop use. The ergonomic handle and straightforward assembly reduce fumbling and let technicians apply force with control for a safer, cleaner removal.

• Heat-treated alloy components resist bending and wear over time.
• Ergonomic handle and coarse-thread forcing screw for controlled pulling.
• Complete kit: multiple bolts and adapters included for right fitment.

How does this tool save time during engine service?

By eliminating the need to remove the radiator in many jobs, the clip-in puller minimizes teardown and reassembly steps—often the most time-consuming portions of a balancer replacement. The included adapters cut trial-and-error fitting, letting you start the extraction immediately.

• Clip-in installation avoids radiator and accessory removal in most setups.
• Multiple adapters reduce downtime finding the correct bolt size.
• Quick setup and a single central forcing screw speed extraction cycles.

Who is this for: The OEMTOOLS 25264 is aimed at professional mechanics, mobile techs, and experienced DIYers who frequently service GM LS engines or specific Chrysler/Jeep/Dodge powerplants and need a reliable, time-saving solution for harmonic balancer removal. If you work on Silverado, Camaro, or late-model V6/V8 engines without tapped balancers and want a durable, ready-to-use puller kit, this tool belongs in your specialty toolbox.
