It's a complete crank assembly, which should include the main bearings (model 83A195, size 25x15x55mm) and other related parts – the description mentions it comes with the crank and 5 additional parts. It's built from strong alloys to handle the stress of a two-stroke engine. Replacing a crankshaft is a major engine repair job; you'll need to split the engine cases to install it. This is usually done when the connecting rod bearings are worn out, causing knocking or loss of performance. It's crucial to compare the pictures and specs carefully with your old crankshaft to make sure it's the right one. If you're rebuilding your Blaster's motor, a new crank like this is essential for getting many more miles of riding out of your ATV.
