Manufactured from high-grade forged alloy steel and subjected to rigorous heat treatment, it ensures exceptional tensile strength and superior fatigue resistance under extreme engine pressures.Key features include advanced micro-polishing on all journal surfaces to minimize friction and a dynamically balanced design that significantly reduces vibration. This contributes to smoother engine operation, enhanced horsepower output, and improved fuel efficiency. Each crankshaft undergoes stringent quality control, including magnetic particle inspection (MPI), to guarantee it meets or exceeds strict OEM specifications for dimensional accuracy and material integrity.Product Advantage
1. Premium Material for Maximum Durability & Engine Performance
Crafted from high-grade 42CrMo alloy steel, this performance crankshaft offers superior tensile strength and wear resistance compared to standard components. It undergoes a precise nitriding surface treatment, creating a hardened layer of 0.3mm to 0.5mm, which significantly boosts its fatigue strength and resistance to abrasion. This ensures exceptional reliability under high-stress conditions, directly contributing to stable engine performance and a dramatically extended service life, providing you with a truly durable engine solution.2. Precision Micro-Polishing for Reduced Friction
Every journal surface on this high-performance engine crankshaft is micro-finished to an exceptional surface roughness of just Ra ≤ 0.2 μm. This ultra-smooth finish minimizes friction with the engine bearings, leading to reduced operational resistance. The result is a noticeable improvement in fuel efficiency, a slight increase in horsepower output, and lower overall engine operating temperatures. This advanced polishing technique is critical for maximizing engine efficiency and longevity.3. Dynamic Balancing for Superior Engine Stability
To ensure incredibly smooth operation, each crankshaft undergoes a rigorous dynamic balancing process. We calibrate the component to an industry-standard balance level of G6.3 or better. This high-precision balancing drastically reduces engine vibration and noise, which minimizes stress on adjacent engine parts. The outcome is a smoother, quieter, and more refined engine run, enhancing driving comfort and protecting the entire engine assembly from premature wear.4. Rigorous OEM-Standard Quality Assurance
We build trust through verifiable quality. Every 480-1005011 crankshaft is 100% tested to meet or exceed strict OEM specifications for dimensional accuracy. Our non-destructive testing protocol includes Magnetic Particle Inspection (MPI) to detect any surface or sub-surface flaws that are invisible to the naked eye. This commitment to zero-defect manufacturing guarantees that you receive a component that delivers flawless fit and uncompromising reliability, right out of the box.

Product Operate Guide
For optimal performance and safety, we strongly recommend that installation is performed by a qualified mechanic in a properly equipped workshop. Correct handling is crucial. Always store the crankshaft horizontally in a clean, dry environment to prevent corrosion or distortion. Before installation, ensure all engine block surfaces, oil passages, and new bearing shells are meticulously clean. Pre-lubricate all journal surfaces with the appropriate engine oil to prevent startup wear. Adhering to the manufacturer's specified torque sequence and values during assembly is critical for ensuring proper engine balance and long-term reliability.
