Good To Know

Q: Are these connecting rods sold individually or as a set? A: They are supplied as a set of 8 connecting rods, enough for one V8 engine. Q: Do these rods use a floating or pressed pin? A: These are floating pin connecting rods, so the wrist pin rotates freely in the rod bore. A: Confirm your engine code and serial number before ordering.

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