AFEISOL Harmonic Balancer Puller for GM LS Crank Pulleys — 3-Claw Clamp, Carbon Steel (25264)

AFEISOL 25264 is a clamp-style harmonic balancer puller engineered to remove non-threaded GM LS-series crank pulleys quickly and safely without unbolting the balancer.

This AFEISOL puller is built for GM small-block and several V6/V8 engines where the harmonic balancer does not have threaded puller holes. It uses a three-claw clamp that grips the backing of the pulley to apply even extraction force, eliminating the need to remove the radiator or to find balancers with threaded mounting points. Constructed from high-strength carbon steel with a corrosion-resistant finish, this tool prioritizes durability and repeatable performance in workshop and DIY settings.

Which GM engines and models does this puller work with?

The AFEISOL 25264 is compatible with many LS and other GM platforms that use non-threaded harmonic balancers. It fits common LS displacements and numerous V6/V8 GM engines, but it is not universal—verify your balancer type before purchasing.

• Compatible: 5.3L, 5.7L LS1, 6.0L LS2, 6.2L LS3, 7.0L and GM 3.5L V6, 3.6L V6, 4.7L V8, 5.7L V8, 6.1L V8.
• Not compatible: some pre-1997 LT1/LT4 5.7L with threaded holes, Ford 5.0L Coyote (2018+ updated), Dodge/Ram 5.7L Hemi, GM L83/L86/LY6 and other LT-platforms with different designs.
• Only for harmonic balancers WITHOUT threaded mounting holes; do not buy for threaded balancers.

How does the clamp design make removal easier than traditional pullers?

Instead of relying on bolts inserted into threaded balancer holes, the AFEISOL puller clamps behind the pulley using three evenly spaced claws. This approach prevents damage to the balancer face, distributes extraction force uniformly, and allows faster set-up and teardown.

• Three-claw buckle attachment secures the puller to the pulley back for even tension.
• Clamping method removes the need to bolt into the balancer, saving time.
• Reduces risk of pulley sliding or surface gouging compared with single-point pullers.

Will I need to remove the radiator or other components to use it?

One of the practical advantages of this puller is that it frequently avoids radiator removal on many LS-style engines. The compact clamp and center-forcing screw approach give room to extract the pulley in confined engine bays.

• Designed to clear common engine bay obstructions—often no radiator removal.
• Center forcing screw applies axial pull while claws hold the pulley steady.
• Saves labor time and reduces disassembly of surrounding components.

What materials and durability features should I expect from this tool?

The AFEISOL puller is made of hardened carbon steel to resist bending and deformation under high extraction loads, and it has a protective black coating to slow corrosion. That combination supports repeated shop use and storage without premature wear.

• High-quality carbon steel construction for strength and hardness.
• Black corrosion-resistant finish extends service life in garages.
• Built to withstand heavy compression forces for repeated removals.

Who is this tool for? The AFEISOL 25264 is aimed at professional mechanics, restoration shops, and experienced DIYers working on GM LS-family motors and compatible V6/V8 engines that feature non-threaded harmonic balancers. If you frequently service GM small-blocks or need a safer, faster way to remove crank pulleys without threaded balancer holes, this puller offers a durable, clamp-style solution. Confirm your engine and balancer type before ordering—this tool is not suitable for balancers with threaded removal holes or several newer/other-platform engines.
