Lisle 77080 19 Mm Harmonic Balancer Socket - Heavy-Duty Impact Tool

Our review of the Lisle 77080 harmonic balancer socket finds it is best suited for mechanics and DIYers who need a focused, heavy-duty tool to remove stubborn crankshaft pulley bolts quickly. The socket is designed with more than three times the mass of a standard socket to deliver increased impact energy, which makes the difference when using an impact wrench or air tool. In short, this is a purpose-built 19 mm impact socket for Honda engines and other 19 mm applications where fast, reliable bolt removal matters.

Key Features

• Heavy-Duty Mass: The socket's greater mass directs more energy into the bolt, improving release speed when used with an impact wrench.
• 19 mm Fit: Intended for Honda engines that use a 19 mm hex pulley damper bolt and other 19 mm applications, providing a specific fit for common crankshaft pulley bolts.
• Impact Quality Steel: Made from heat-treated alloy steel to withstand repeated impact use and resist premature wear.
• 1/2 in Drive Compatibility: Designed for use with a 1/2 in drive, making it compatible with most mid-size impact wrenches and air guns.
• Patented Design: Covered by Patent 10,040,176, reflecting a specialized engineering approach to harmonic balancer removal.

Who It's For

This socket is aimed at professional technicians and serious home mechanics who routinely work on Honda engines or any vehicle that uses a 19 mm hex pulley damper bolt. If the job calls for fast crankshaft pulley bolt removal with an impact wrench, the added mass and impact-rated construction make this tool a time-saver.

It is less suitable for casual users who only occasionally remove a harmonic balancer or for those who prefer non-impact, hand-tool methods; if you only use hand ratchets or rarely encounter 19 mm damper bolts, a standard socket set may be more economical.

Pros & Cons

Pros

• Delivers rapid bolt release with impact wrenches thanks to the increased socket mass.
• Durable, heat-treated alloy steel construction holds up under repeated impact use.
• Clear compatibility with 1/2 in drive tools makes it easy to integrate into existing air tool setups.
• Patent-backed design aims to solve common harmonic balancer removal challenges.

Cons

• Some customers report mixed fit on certain dampers, so fitment can vary by application.
• Heavier mass means the socket is bulkier than standard sockets and not ideal for tight clearance jobs.

Frequently Asked Questions

Will this socket work on non-Honda engines?
Yes, it can be used on any application that requires a 19 mm hex socket and accepts a 1/2 in drive, but always check the pulley bolt head size first.

Is this socket safe for use with impact wrenches?
Yes, it is made from heat-treated, impact-quality alloy steel and is specifically intended for use with impact wrenches and air guns.

Does the socket fit all harmonic balancers?
Most 19 mm hex pulley damper bolts will fit, but some customers report mixed fit, so verify clearance and bolt head size on your vehicle before purchase.
