Specs At A Glance

Good To Know

Q: Does this kit come with everything needed for a crank rebuild? A: It is supplied as a connecting rod kit that includes the rod, crank pin, and bearing, but crankcase seals and gaskets are usually ordered separately. Check the parts diagram for your specific model to confirm what else is needed.

Q: How do I confirm this rod fits my SX-F 350? A: Match the 03.6366 reference against your engine parts listing and confirm the model year falls in the 2016 to 2026 range. Crank rebuilds also require pressing and truing work, so a workshop manual or an experienced engine builder is recommended.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
