Harmonic Balancer Puller for GM and Chrysler - Clip-In Engine Damper

In this review the ReluxGo 25264 harmonic balancer puller is assessed for DIY mechanics and professional technicians who need a quick, non-destructive way to remove crank pulleys on many GM and Chrysler-family engines. The single biggest reason to buy is its clip-in design that grips dampers without requiring tapped holes, making removal faster on engines where threaded puller holes are absent. The reviewer found it straightforward to use, built from heat-treated AISI 1045 steel, and especially useful when working on LS family smallblock motors.

Key Features

• Clip-in design: allows secure gripping of harmonic balancers without bolting into the pulley, which speeds removal on engines without tapped holes.
• Broad compatibility: fits a range of GM V8 and LS engines and many Chrysler, Jeep and Dodge V6 and V8 applications, covering common workshop jobs.
• Durable construction: made from heat-treated AISI 1045 medium carbon steel to resist wear and provide steady leverage during pulling tasks.
• Easy to use: the tool set up and pull procedure are simple enough for one technician to operate without special fixtures.
• Clear limitations: the tool explicitly does not fit older 1997 or earlier GM LT series with threaded holes, recent 2018+ Ford 5.0 Coyote dampers, or typical truck pulleys.

Who It's For

This puller is aimed at home mechanics, engine builders and repair shops that frequently service small block GM LS engines (5.3 L, LS1/LS2/LS3 families) and a range of Chrysler, Jeep and Dodge V6 and V8 engines where traditional tapped-hole pullers cannot be used. It is a practical choice when you need a fast, reliable removal without risking damage to the damper face.

It is not the right choice for owners of 1997 or earlier GM LT series engines that use threaded balancer holes, for technicians working on 2018+ Ford 5.0 engines or newer Coyote balancers, or for jobs that involve truck pulleys that differ in shape and engagement.

Pros & Cons

Pros

• Clip-in grip removes dampers without bolting into the pulley, reducing work time.
• Solid AISI 1045 steel construction gives a sturdy feel and good longevity under normal use.
• Works across many popular GM LS and several Chrysler, Jeep and Dodge engine families, making it versatile.

Cons

• Fit is mixed on some platforms; users reported compatibility issues with certain Dodge 3.6 Pentastar engines.
• There are customer reports raising questions about long-term durability under heavy professional shop abuse.

Our Verdict

The ReluxGo harmonic balancer puller is a practical, cost-effective tool for mechanics working on many GM LS engines and a broad set of Chrysler, Jeep and Dodge V6/V8s who need a non-bolting removal method. It delivers solid build quality and ease of use, though buyers should verify fit for specific models like some Pentastar engines. For routine engine work this puller offers good value and saves time compared with threaded-hole pullers.
