GM Harmonic Balancer Puller LS Crank Pulley Puller - Clip-In

In this review of the OEMTOOLS 25264 harmonic balancer puller, the bottom line is simple: it is a practical, time-saving specialty tool for mechanics and DIYers who work on GM LS engines and many Chrysler/Jeep/Dodge applications. The single biggest reason to buy is the clip-in design that allows removal of crank pulleys and balancers without taking out the radiator, which noticeably speeds up common front-end engine jobs. For shops or home garages that see frequent pulley service on 5.3L and similar engines, this tool delivers reliable performance and durability.

Key Features

• Clip-in design: Lets you remove harmonic balancers without radiator removal, saving teardown time on front-end engine work.
• Wide engine compatibility: Fits GM 5.3L, 5.7 LS1, 6.0 LS2, 6.2 LS3 and multiple Chrysler, Jeep, Dodge V6/V8 engines for versatile use across vehicles.
• Durable construction: Built from high-strength materials so the puller stands up to repeated shop use and heavy pulls.
• Included adapters and bolts: Comes with the necessary accessories so you can tackle different balancer sizes and styles without extra purchases.
• Ergonomic handle: Provides a secure grip to control force application and reduce hand fatigue during removal.

Who It's For

The OEMTOOLS 25264 is best for professional mechanics, mobile technicians, and informed DIYers who regularly work on GM LS series engines or Chrysler/Jeep/Dodge vehicles and need a faster way to remove harmonic balancers without removing the radiator. It is particularly useful in situations where reduced disassembly lowers job time and cost.

Those who should look elsewhere include owners of rare vehicles or non-compatible engines not listed among the supported displacements, and anyone who prefers a universal puller for every possible pulley design rather than a tool optimized for LS and specified Chrysler engines. Verify fit on your exact model before purchasing.
