Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

What material is best for high-performance connecting rods?

For maximum RPM and lightweighting, Titanium Ti-6Al-4V is ideal. For extreme load and durability in daily drivers, forged 4340 steel provides the best balance of strength and cost.

How do you ensure the balance of the connecting rods?

We utilize high-precision dynamic balancing machines and CNC grinding to ensure each rod in a set matches within ±0.2g, minimizing crankshaft vibration.

What is the benefit of shot-peening on a connecting rod?

Shot-peening creates a layer of compressive residual stress on the surface, which prevents the initiation of fatigue cracks and significantly extends the component's life.

Can you produce custom dimensions for specialized engines?

Yes, we provide full OEM/ODM services. From initial CAD design to sample prototyping, we can engineer rods to any specific geometry requested.

What is the typical lead time for custom samples?

Our rapid prototyping cycle allows us to deliver fully finished, tested samples within 7 to 10 working days.

How do you handle shipping for international orders?

We use industrial-grade anti-corrosion packaging and vacuum sealing, shipping via global air freight to ensure parts arrive in pristine condition.
