It fits 24 mm hex pulley damper bolts and accepts a 1\/2\" drive impact wrench, combining durable GB 40Cr alloy steel construction with a geometry built to resist slippage and handle high torque impact use.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this socket make removing stubborn crank bolts easier?\u003c\/h3\u003e\n\u003cp\u003eThe 77070 multiplies delivered momentum so an impact wrench can break loose seized or high-torque crank bolts more reliably. Its deep, counter-weighted body centers the force and prevents the socket from lifting out of the bolt head under impact.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e3x momentum gearing (vs standard impact sockets) for stronger impulse force\u003c\/li\u003e\n  \u003cli\u003eDeep design reaches recessed crank bolt heads on LS engines\u003c\/li\u003e\n  \u003cli\u003e6-point contact reduces rounding and slippage during removal\u003c\/li\u003e\n  \u003cli\u003eOptimized for use with 1\/2\" drive impact tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this fit my GM LS engine and other 24 mm applications?\u003c\/h3\u003e\n\u003cp\u003eThe socket is specified for 24 mm hex harmonic balancer\/crank bolts used across many GM LS platforms.

Because the socket’s counter-weighted profile stabilizes the tool, you typically don’t need to lock the crankshaft when removing the bolt, but follow vehicle-specific service procedures and torque specs during reinstallation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUse with a quality 1\/2\" drive impact wrench for best results\u003c\/li\u003e\n  \u003cli\u003eVerify full seating on the bolt to avoid rounding\u003c\/li\u003e\n  \u003cli\u003eWhen reinstalling, follow manufacturer torque specifications\u003c\/li\u003e\n  \u003cli\u003eWear eye protection and appropriate PPE during impact use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWho is this tool for?\u003c\/strong\u003e The Sunluway 77070 24mm crank bolt socket is intended for professional mechanics, automotive enthusiasts, and home garages tackling GM LS engine maintenance or other high-torque 24 mm fastener jobs. If you need a dependable, impact-rated socket that resists slippage and stands up to repeated heavy use, this tool is designed to improve success and reduce damage to bolt heads during crank pulley removal and installation.\u003c\/p\u003e\n\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this socket work with a 1\/2\" drive impact wrench?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
