Sunluway Harmonic Balancer Socket 19mm Crank Bolt 77080 — 1/2in Drive, Deep Counter-Weighted Impact Socket for Honda

If you work on Honda engines that use a 19mm hex pulley damper bolt, this Sunluway socket simplifies crank pulley removal. Built from heat-treated GB 40CR alloy steel and engineered with a deep counter-weighted profile, it concentrates impact energy to break stubborn bolts free while preserving the bolt’s head. The 1/2" square drive and 89mm overall length are sized to fit common Honda layouts and provide clearance for access with impact wrenches.

How does this socket deliver more torque than a standard impact socket?

The Sunluway 77080 has a higher mass and a deep counter-weighted construction that channels more of the impact wrench’s energy directly into the bolt. That extra momentum helps overcome tightly torqued or seized crank bolts without relying on excessive manual force.

• Over three times the mass of typical sockets to increase delivered energy.
• Deep, counter-weighted geometry focuses impact force on the bolt head.
• 6-point contact profile prevents rounding and improves torque transfer.

Will this fit my Honda crank pulley bolt and common tool setups?

This model is designed specifically for 19mm hex crank/damper bolts and works with any 1/2" drive impact wrench or breaker bar. The 89mm overall length offers a balance of reach and clearance for most Honda engine layouts without interfering with nearby components.

• 19mm hex socket size for Honda crank pulley/damper bolts.
• 1/2" square drive to match standard impact tools and breakers.
• 89mm overall length for accessibility in tight engine bays.

What materials and finish protect this socket under heavy use?

Sunluway manufactures the socket from heat-treated GB 40CR alloy steel for elevated strength and impact resistance versus ordinary steel. A robust finish and precise machining reduce wear and help the socket withstand repeated impact cycles.

• Heat-treated GB 40CR alloy steel for long-term durability.
• Impact-rated design intended for use with impact wrenches.
• 6-point internal geometry reduces fastener rounding and slippage.

How easy is it to use this harmonic balancer socket in a repair job?

The socket is ready to install: slide it onto the 19mm crank bolt and attach your 1/2" drive impact or breaker bar. Because the socket’s weight and contact pattern focus force on the bolt, you normally won’t need to hold the crankshaft separately, making removal faster and safer.

• Quick installation on 19mm crank bolts with a 1/2" drive tool.
• Designed to reduce slippage and eliminate the need to hold the crankshaft.
• Compact length allows use in confined engine compartments.

Who is this for: This Sunluway Harmonic Balancer Socket 77080 is aimed at professional mechanics, home DIYers, and automotive technicians who frequently remove Honda crank pulleys or work on engines with 19mm damper bolts. If you need an impact-resistant 19mm socket that minimizes bolt rounding and boosts the effective torque from your impact wrench, this tool is built for those demanding removal tasks. The product includes a 30-day full refund policy and a one-year warranty for added peace of mind.
