ENGINE CRANKSHAFT

The engine crankshaft is a central component of the crankshaft assembly, converting the reciprocating motion of the pistons into rotational motion. Its condition directly affects engine balance, vibration levels, and overall durability.

Manufactured from high-strength steel or cast iron, the crankshaft features main journals, connecting rod journals, counterweights, and internal oil passages. It operates together with connecting rods, pistons, bearings, flywheel, and the lubrication system.

Common wear or damage symptoms include low oil pressure, knocking noise, excessive vibration, journal scoring, or structural deformation. Severe damage may result in engine seizure.

Our catalog includes crankshafts for petrol and diesel engines across various vehicle brands. Genuine factory crankshafts, reconditioned units, and tested used components are available.

Used crankshafts are inspected for runout, journal condition, absence of cracks, overheating signs, and geometry accuracy. Oversize or undersize specifications are indicated when applicable.

Selection is based on VIN number, engine code, cylinder configuration, displacement, and part number. Crankshaft replacement is typically required during major engine rebuilds or after critical mechanical failure.

The company объединяет several well‑known automotive brands including Chevrolet, GMC, Cadillac and Buick and is a major manufacturer of vehicles, powertrains and genuine automotive components. Under the GM brand a wide range of original spare parts and components is produced for vehicles of the group, including engine parts, cooling system components, transmission elements, suspension parts, braking systems, electronic modules, sensors, fuel system components and body parts. Genuine GM parts are developed according to factory technical specifications and undergo strict quality control at every stage of production. This ensures precise compatibility with GM vehicles, reliable operation of vehicle systems and preservation of factory performance characteristics. According to feedback from vehicle owners and automotive service professionals, GM genuine components are known for consistent manufacturing quality, solid reliability and long service life. Many users report precise fitment without the need for modifications and stable vehicle performance after replacing components. The most commonly mentioned drawback is the relatively higher price compared with some aftermarket alternatives, although many vehicle owners consider genuine GM parts a justified choice due to their reliability, durability and compliance with manufacturer standards.

Additional information

The engine crankshaft is a core internal component that converts piston movement into rotation and passes torque through the engine. If the crankshaft is worn or damaged, the engine may develop knocking, vibration, low oil pressure, or metal particles in the oil, so correct selection matters.

When choosing this part, always check the OEM number first. For this item, the confirmed reference is 55575150, with cross-number 55511543 also listed. Similar parts can look alike but still differ in design, so matching by number is the safest way to avoid a wrong purchase.

This listing is for a used original GM part from dismantling. It is a practical choice when you need a genuine factory crankshaft with verified catalog identification rather than an uncertain substitute. That makes it suitable for engine repair where exact fitment and original specification are important.
