Description
A Polaris 550cc Fuji-powered machine due for a bottom-end rebuild needs more than a fresh crank; it needs every gasket and bearing at that level of the engine handled at the same time, which is what this kit is built around.
Rather than sourcing a crankshaft assembly, main bearings, and a separate bottom-end gasket kit as individual items, this package bundles them under one part number so the rebuild can move forward without a parts-chasing delay. Bottom-end work is disruptive enough on its own, and a rider who has already pulled the engine down benefits from having the sealing and rotating components matched and ready in one box.
- Contains a crankshaft assembly for the Polaris 550cc Fuji engine
- Includes main bearings sized for that crankshaft
- Bundles a complete bottom-end gasket kit in the same package
- Everything supplied under one part number for a single, simple order
- Manufactured by leading gasket and component suppliers
- Inspected for quality and accuracy before packaging
- A must-have for getting a bottom-end rebuild done right
Designed around the Polaris 550cc Fuji engine, this kit suits riders and shops planning a full bottom-end rebuild who want the crank, bearings, and gaskets covered in one purchase.
