Also, verify your engine’s model designation (e.g., 3TNC80).

Q2: Is this sold as a single rod or as a full set?
A2> This product is typically sold as a single connecting rod. For a complete engine overhaul, you will need to purchase one rod per cylinder. Please check the product listing details or contact our sales team to confirm the unit of sale for your order.

Q3: What other components should I replace during a connecting rod installation?
A3: For a reliable rebuild, it is highly recommended to also replace the corresponding connecting rod bolts (stretch bolts), bearing shells, and piston pin bushing. Always inspect the piston, piston rings, and crankshaft journal for wear. Using a matched set of new components ensures balanced operation and long engine life.
