FAQ

1. Will this connecting rod fit my L3E engine if it has a different wrist pin size?

This specific rod is designed for an 18mm wrist pin hole. If your original rod uses a different pin diameter (e.g., 17mm or 20mm), this part will not be compatible. You must verify your piston pin size and the engine block code before ordering.

2. Do I need to replace the connecting rod bolts during installation?

Yes. It is a critical safety and performance requirement to always use new connecting rod bolts when installing a new rod. The bolts are torque-to-yield fasteners and should never be reused. We recommend purchasing a connecting rod bolt set separately for a complete rebuild.

3. What is the standard weight class of this rod, and can it be matched?

This rod is supplied as a standard weight class part. For high-performance or precision racing applications, it is recommended to have a set of rods balanced as a set by a qualified machine shop to ensure perfect engine balance and minimize vibration.
