SBC Crank Turning Socket

The PROFORM SBC Crank Turning Socket (SKU: PFM66901) is a precision tool designed for engine builders, mechanics, and automotive enthusiasts working on Small Block Chevy, V6, and 4-cylinder engines. This specialized crankshaft turning tool eliminates the frustration of manually rotating the crankshaft during assembly, timing checks, and top-dead-center positioning. Whether you're performing valve-to-piston clearance verification, distributor installation, or degree-wheel work, this socket streamlines critical engine development tasks that demand accuracy and repeatability.

Constructed from durable aluminum, the SBC Crank Turning Socket features a 1/2-inch drive design compatible with standard breaker bars and torque wrenches, allowing smooth, controlled crankshaft rotation with the precision necessary for engine work. The snout socket design engages the crankshaft snout directly—the tapered front end of the crank that protrudes from the engine block—ensuring a secure, centered fit that prevents damage to critical engine components. Weighing just 0.23 lbs and measuring 4.55 x 1.85 x 7 inches, this compact tool stores easily in any engine shop while delivering the mechanical advantage needed to turn stubborn cranks without straining or improvising with inferior methods.

Professional engine builders and serious home mechanics rely on the SBC Crank Turning Socket when setting camshaft timing, locking the crankshaft for keyway alignment, or performing top-dead-center verification before final assembly. The 1/2-inch drive accommodates any standard socket wrench, extension, or breaker bar in your shop, making it a versatile addition to any engine building station. For Small Block Chevy applications—including LS variants, LS1, LS2, LS3, and comparable displacement platforms—this tool proves indispensable during critical phases of engine modification, rebuild, and performance tuning.
