Frequently Asked Questions

Q: Does this kit come with the main bearings and seals?
A: No, this is the crankshaft assembly. We recommend purchasing a fresh set of main bearings and a complete top/bottom end gasket kit when performing a crankshaft replacement.

Q: Is this crankshaft balanced exactly like the factory original?
A: Yes, Hot Rods builds these to meet or exceed OEM specifications, meaning it is balanced and trued for a drop-in fitment.

Expert Pro-Tip: When installing a new crankshaft, never force it into the cases. Use a proper crankshaft puller tool to draw the crank into the main bearings. Also, check your transmission oil for metal debris before assembly—if your old crank failed, you need to ensure the bottom end is surgically clean before firing it up.
