Frequently Asked Questions

Q: Does this kit come with the main bearings or seals?
A: No, this is a complete crankshaft assembly. We highly recommend installing a new set of main bearings and high-quality seals whenever replacing a crankshaft to ensure maximum engine longevity and air-tight crankcase pressure.

Q: Is this crankshaft balanced?
A: Yes, Hot Rods crankshafts are factory trued and balanced to OEM specifications, making them ready to install right out of the box.

Expert Pro-Tip: When installing a new 2-stroke crank, never force it into the cases. Always use a proper crank puller tool and ensure your engine cases are clean and free of old gasket material. Cold-soaking the crankshaft in the freezer for an hour before installation can also make seating it into the main bearings significantly easier and reduces the risk of marring the journal surfaces.
