Specs At A Glance

Good To Know

Q: Do I need to replace all connecting rods at once? A: Replacing the full set is standard practice during any bottom-end rebuild, since matched rods keep rotating mass consistent across cylinders.

Q: Is machine work required during installation? A: Rod installation typically involves measuring crankpin clearance and verifying torque specs, so having the crankshaft inspected by a machinist before assembly 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.
