rods ensure optimal performance in both passenger vehicles and
high-performance engines.
Key Features & Benefits
1. Premium Material & Manufacturing
Material: High-grade carbon steel (C45, 42CrMo, or custom alloys)
Process: Precision closed-die forging for grain flow optimization
Heat Treatment: Quenched & tempered for enhanced fatigue resistance
Machining: CNC-processed for tight tolerances (±0.02mm)
2. Superior Strength & Durability
Tensile Strength: 850–1100 MPa
Yield Strength: 650–900 MPa
Impact Toughness: ≥50 J (Charpy V-notch)
Fatigue Life: 1M+ cycles at max load
3. Precision Engineering
Weight Matching: Balanced to ±1g per set
Bore Precision: H7 tolerance for perfect crankpin alignment
Surface Finish: Shot-peened for stress relief and microfinish (Ra
≤0.8μm)
4. Application Versatility
Passenger Cars (1.5L–3.0L engines)
Performance & Racing Engines (turbocharged applications)
Commercial Vehicles (diesel & petrol variants)
Aftermarket Upgrades (high-revving builds)

Product application:
1. OEM Vehicle Manufacturing
Designed for original engine assembly in passenger cars, SUVs, and
light trucks
Meets strict automotive OEM standards for durability and
performance
Compatible with 1.5L–6.0L gasoline and diesel engines
2. High-Performance & Racing Engines
Ideal for turbocharged, supercharged, and high-RPM builds
Used in track cars, drift cars, and drag racing applications
Handles extreme cylinder pressures (up to 200+ bar in boosted
engines)
3. Engine Rebuilding & Aftermarket Upgrades
Perfect for engine overhauls when replacing worn OEM rods
Popular choice for performance tuning (increased power &
reliability)
Enables higher rev limits compared to cast rods
4. Commercial & Heavy-Duty Vehicles
Suitable for light commercial vehicles (vans, pickups)
Used in diesel engines requiring high torque resistance
Withstands long-haul stress better than standard rods
5. Specialty Vehicle Applications
Classic car restorations (when OEM parts are unavailable)
Off-road and rally vehicles (handles vibration/shock loads)
Marine and small aircraft engines (where weight/strength ratio is
critical)
