GEAROLL Harmonic Balancer Puller Installer Kit — Adjustable 3-Jaw Set, 4 Forcing Rods, Hardened Steel

This complete puller/installer package brings workshop-grade durability and adaptability to DIY mechanics and professional techs alike. The kit includes interchangeable jaws, multiple forcing rods, a balancer holder and a storage case so you can tackle both older and newer engine pulleys without removing the radiator or performing extensive disassembly. Built from hardened steel with a protective finish, the set is made to withstand repeated use and resist corrosion in busy garages.

How does this puller work on different engine models?

The GEAROLL set is engineered to fit a broad range of engines by swapping jaws and forcing rods to match pulley thickness and pull depth. Three thicker jaws handle older, deeper-seated balancers while three thinner jaws fit modern, low-profile dampers. Forcing rods in four lengths let you create the correct reach so the center forcing screw presses on the crank snout rather than damaging the pulley.

• Six jaw options: three thick, three thin for older and newer pulleys
• Four forcing rod lengths: 100, 135, 165, 185 mm for reach versatility
• 3/8" drive forcing screw (90 mm) for controlled extraction force

Can it save time compared with other removal methods?

Yes — the tool is made to extract pressed-on harmonic balancers while leaving surrounding components in place. In many common applications you can remove the damper without draining the cooling system or dismantling the radiator assembly, which significantly reduces labor time. The design centers pulling force through the crankshaft to get safe, straight extraction.

• Single-center retainer bolt operation for faster setup
• Avoids radiator removal in many vehicle layouts
• Balanced jaw grip minimizes slippage and damage to the pulley face

What materials and build quality can I expect?

The kit uses hardened steel components and a black oxide surface finish to improve strength and resist rust in workshop environments. Heavy-duty construction keeps threads and jaws from deforming under repeated torque and impact. A fitted storage case and included gloves help protect parts and keep the set organized between jobs.

• High-hardness steel for durability under load
• Black oxide finish for corrosion resistance
• Supplied gloves and a storage case for transport and protection

Who this kit is for: The GEAROLL Harmonic Balancer Puller Installer Kit suits independent mechanics, home enthusiasts and fleet technicians who service American V8s and a range of import engines. It’s especially useful when you need a reliable, reusable tool for pressed-on dampers across model years — from older Chevrolet and Ford engines to later-model GM V8s and compatible Mitsubishi or Chrysler applications. If you regularly do engine front-end work or want a single, adaptable puller set to cover many vehicles, this kit delivers the reach, jaw options and build quality to make pulleys removal and installation faster and safer.
