Sunluway GM Harmonic Balancer Puller & Installer Set for 1997+ LS/LT V8 Engines — 3-Jaw Puller with Thrust Bearing

Sunluway's GM 25264 harmonic balancer puller and LS installer is a two-piece crank pulley tool set built to remove and install harmonic balancers on GM LS/LT V8 engines from 1997 onward without needing tapped holes.

This all-in-one kit combines a 3-jaw puller and a thrust-bearing installer to tackle crank pulley jobs on Camaro, Corvette, GTO, Trans Am, G8 and many LS-powered trucks. Made from alloy steel with corrosion-resistant finish and included hardware, the set is engineered to grip, extract and press harmonic balancers with reduced risk to the crank snout. It covers a broad range of GM LS-series and compatible Chrysler engines, simplifies a common service task, and stores neatly thanks to the installer’s hangable cap.

How does this puller remove a harmonic balancer without tapped holes?

The 3-jaw puller uses a clip-in engagement that secures around the balancer nose so you can apply even extraction force without relying on threaded crankshaft holes. Because it grips the outer diameter, you avoid radiator removal and the need to access rear-mounted fasteners.

• 3-jaw design for a firm, centered grip
• Clip-in setup eliminates the need for crank tapped holes
• Allows removal while keeping surrounding components in place

What makes the installer safe for the crankshaft during fitting?

The installer includes a thrust-bearing assembly so the balancer can be threaded evenly onto the crank without excessive axial force. This reduces binding and the risk of damaging the crank snout or the new balancer during install.

• Thrust bearing to allow smooth, controlled pressing
• Threaded rod and flange nut distribute pressure evenly
• Aluminum washers and galvanized nuts for reliable hardware contact

Which engines and years are compatible with this Sunluway set?

This toolset is intended for GM LS and LT V8 engines from 1997 to current generations, including LS1, LS2, LS3, LS4, LS6, LSX, LSA and later V8s. It also lists compatibility with select Chrysler/Dodge/Jeep V6 and V8 models where applications share similar balancer fitment. Note the puller/installer is not designed for older 1991–1997 LT1 Gen 2 5.7L engines with different crank threads, nor for some 2018+ Coyote balancers.

• Covers 5.3L, 5.7L (LS1), 6.0L, 6.2L, 7.0L and many LS-series engines
• Works for many Chrysler/Dodge/Jeep V6 and V8 balancers listed
• Not compatible with 1991–1997 LT1 Gen 2 or some 2018+ Coyote units

How durable and easy to store is this toolset?

Manufactured from high-strength alloy steel with a black protective coating, the tools resist deformation and corrosion for regular shop use. The installer includes a hangable storage cap and the components are simple to disassemble so you can keep the set organized between jobs.

• Alloy steel construction with corrosion-resistant finish
• Galvanized nuts and aluminum washers for longevity
• Installer cap for convenient hanging and storage

Who is this for: The Sunluway GM 25264 set is aimed at DIY enthusiasts, independent mechanics and performance shops that service GM LS/LT V8 engines and want a reliable, bolt-on solution to remove and install harmonic balancers without invasive disassembly. If you routinely work on Camaro, Corvette, GTO, G8, LS swap projects or service trucks with LS-series engines, this kit speeds the job and reduces risk to the crank while delivering workshop-grade durability.
