ReluxGo Harmonic Balancer Puller 25264 — Clip-Style Crank Pulley Tool for GM LS & Chrysler, Heat-Treated Steel

The ReluxGo 25264 harmonic balancer puller is a clip-style crank pulley removal tool engineered to extract and install harmonic dampers on many GM and Chrysler/Jeep/Dodge engines without needing tapped balancer holes.

When you need to remove or replace an engine harmonic balancer on compatible V6 and V8 engines, the right puller saves time and prevents damage. The ReluxGo 25264 uses a non-tapped, clip-in design that grips the outer edge of the damper, so you don't have to rely on threaded holes in the balancer. Built from heat-treated AISI 1045 medium carbon steel, it resists wear and corrosion for repeated shop use.

How does this puller work on engines without tapped balancer holes?

The ReluxGo 25264 employs a clip-in, expanding jaw arrangement that locks onto the harmonic damper rim and pulls straight from the crank snout using a central forcing screw. Because it does not require bolting into threaded holes, it's suited for modern GM LS-series and many Chrysler-family dampers. The central screw applies steady axial force to remove the balancer without levering against the crank.

• Clip-style jaws expand behind the damper lip for a secure grip.
• Central hex forcing screw drives the balancer off the crank nose smoothly.
• No need for tapped balancer holes—ideal for many LS engines.
• Heat-treated AISI 1045 steel components for durability under load.

Which vehicles and engines is the ReluxGo 25264 compatible with?

This puller covers a broad range of GM and Chrysler/Jeep/Dodge engines, including popular LS-series V8s and several V6 and V8 Chrysler powerplants. It fits 5.3L, 5.7L (LS1), 6.0L (LS2), 6.2L (LS3) and 7.0L GM engines, and many Chrysler/Jeep/Dodge engines such as 3.5L and 3.6L V6, 4.7L V8, 5.7L Hemi, and 6.1L V8. Always confirm your balancer profile before purchase.

• Compatible: GM LS-series engines (5.3L–7.0L) and many Chrysler V6/V8 engines.
• Not compatible: 1997 or earlier GM LT engines with threaded holes.
• Not compatible: 2018+ Ford 5.0 Coyote-style balancers or truck pulleys.
• Check balancer rim shape and clearance to ensure proper jaw engagement.

What materials and build features make this a reliable shop tool?

ReluxGo constructed this puller from AISI 1045 medium carbon steel and applied heat treatment to raise hardness and fatigue resistance. The result is a tool that withstands repeated axial loads and resists deformation while remaining corrosion and wear resistant. Its finish and machining are meant for garage and professional environments where frequent removal and installation is required.

• AISI 1045 medium carbon steel for strength and toughness.
• Heat-treated components to handle pulling forces.*
• Precision-thread central screw for controlled extraction.
• Compact profile to fit in crowded engine bays.

Are there usage tips or limitations to know before buying?

Before using the puller, verify the balancer design and available clearance around the crank pulley. Do not use this tool on engines listed as incompatible, and avoid leveraging it against soft or damaged damper surfaces. If unsure, remove surrounding accessories and reference service manuals for torque and support points.

• Confirm balancer rim shape to ensure clip jaws can engage fully.
• Not for LT-series engines with threaded dampers or 2018+ Coyote balancers.
• Use proper thread lubricant and steady, even force when extracting.
• Support the crank as recommended by the vehicle manufacturer.

Who is this for: The ReluxGo 25264 is aimed at home mechanics, independent shops, and technicians who work on GM LS-series and many Chrysler-family engines and need a non-tapped balancer removal solution. It’s especially useful when the factory balancer lacks threaded holes or when a compact, durable puller is preferred for tight engine compartments. If you service a variety of modern GM and Dodge/Jeep engines and want a robust, reusable tool for harmonic dampers, this model is a practical addition to your tool kit.
