The Sunluway 77070 is purpose-built to fit 24 mm pulley damper bolts and deliver higher momentum than ordinary sockets, so you can break and remove those crank bolts without holding the crankshaft or risking slippage. Constructed from heat-treated GB 40CR alloy steel and designed for use with a 1\/2\" drive impact wrench, this socket combines durability, fit accuracy, and impact resistance for workshop and DIY use.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this socket make removing an LS harmonic balancer easier?\u003c\/h3\u003e\n\u003cp\u003eThe 77070 focuses on delivering torque to the crank bolt head while reducing the need to restrain the crankshaft. Its deep, counter-weighted body centers the force, and the 6-point contact profile grips the bolt to minimize rounding and slipping.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDeep counter-weighted shape centers tool on bolt for stable removal.\u003c\/li\u003e\n  \u003cli\u003e6-point contact reduces bolt rounding and increases torque transfer.\u003c\/li\u003e\n  \u003cli\u003eDesigned for 1\/2\" drive impact wrenches; no crank holding required.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat makes the 77070 stronger than a standard impact socket?\u003c\/h3\u003e\n\u003cp\u003eSunluway engineered this socket to provide roughly three times the momentum delivery of typical sockets, concentrating impact energy where it’s needed to loosen seized crank bolts.
