Specs At A Glance

Good To Know

Q: Do I need to split the cases to install this rod kit? A: Yes, a connecting rod replacement requires splitting the crankcase and pressing the crankshaft apart, so it is a full bottom end job. Professional installation with the correct press tooling is recommended.

Q: Can I reuse my old bearings with this kit? A: Fresh bearings are supplied with the kit and should be used during assembly to protect the new rod. Reusing worn bearings risks premature failure of the rebuilt bottom end.

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