Specs At A Glance

Good To Know

Q: Do I need to replace both rods at once? A: Replacing the full set is standard practice during a rebuild since rods wear as a matched assembly and uneven replacement can affect balance.

Q: Is machine work required for installation? A: Rod installation typically requires pressing and torquing to spec, so professional engine assembly is recommended for correct clearances.

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