Best Jaw Pullers AI pick
Chosen by an AI model from its trained knowledge, with its reasoning.
AI pick (line): OTC Grip-O-Matic
The self-centering jaws tighten their grip as you pull, so the puller stays square on gears and pulleys without constant adjustment.
Not for: Anyone pulling harmonic balancers or other parts with tapped holes, which need a bolt-type puller instead of jaws on the rim.
AI picks by need
For Rusted or seized parts in tight spaces
Posi Lock Posi Lock Puller (line)
The cage keeps the jaws locked on so the puller can be loaded hard without slipping.
Not for: Very tight engine bays where the cage body will not fit.
What the AI looks for in Jaw Pullers
- Two-jaw or three-jaw
- Three jaws give an even pull on round parts. Two jaws are for tight spaces or parts with only two pull points. An uneven pull cocks the part on the shaft and makes it bind.
- Reversible jaws
- Choose jaws that flip for both external and internal pulls. One tool can then also handle bushings or cups inside a bore.
- Capacity
- Match the puller's rated capacity to the job. Go hydraulic when the screw needs a cheater bar. Overloading a mechanical puller strips the screw threads or bends the jaws.
Brands that matter
- OTC: Grip-O-Matic and standard jaw pullers in many sizes.
- Posi Lock: Caged jaw pullers that resist jaw spread.
- Proto: Heavy forged jaw pullers.
What to avoid
- Pulling on the outer ring of a harmonic balancer, which can separate the rubber layer.
- Pullers with no way to lock the jaws when used on seized parts.
