Accurate matching models, professional quality trustworthy

Behind every truck is a sophisticated power system that works silently, and one of the most critical components is the crankshaft. The 4HE1 crankshaft, specially designed for Isuzu NPR/NQR series models, was fully simulated and tested based on the original factory specifications at the beginning of development to ensure seamless connection with each engine component.

Both the dimensional accuracy and the assembly tolerance range have reached the micron level standard control, which greatly reduces the frequency of later maintenance and adjustment. For maintenance service providers, this means higher installed efficiency and lower labor costs, and for car owners, it is a long-term and reliable operation guarantee.

High-strength material casting, bearing the challenges of complex working conditions

A good commercial vehicle is inseparable from a strong heart, and the soul of this heart lies in its core component-the quality of the crankshaft directly affects the performance of the vehicle. This 4HE1 model is made of special alloy steel after high temperature quenching and multiple forging forming process, with super tensile strength and fatigue limit value.

Maintaining structural integrity without deformation even in the face of severe road conditions such as steep climb or continuous rapid acceleration and deceleration. It is such strict technical requirements that it can still play a stable role in various extreme temperature and humidity environments.

Power transmission core components to ensure the smooth operation of the engine

when fuel combustion generates thrust to drive the piston up and down, how to effectively convert these discrete forces into kinetic energy in a unified direction? the answer lies in this seemingly insignificant but vital mechanical component. Through the rigorous design layout, this crankshaft achieves perfect energy conversion path planning, which greatly reduces the loss of invalid vibration.

Each rotation is given the most ideal angle offset compensation scheme, so that the entire drive chain is smoother and quieter. This not only helps to extend the working life of other related parts such as connecting rod bearings, but also significantly improves fuel economy and driving comfort index values.

A wide range of scenarios to meet diverse operational needs

More than just simple replacement parts, a large number of logistics fleets are now purchasing such high-performance parts in bulk for regular maintenance and renewal plans. Because it not only serves the daily urban distribution business, but also has excellent performance in mountain roads and even construction sites.

Whether it is the trunk transport vehicles that shuttle around the clock in the highway network around the country, or the city distribution vanguard members who are busy between the streets of the town all day long, they can benefit from the extraordinary experience of the journey of change brought about by high-end spare parts.

Craftsmanship Creates Industry Benchmark Level

the whole process from raw material storage inspection to finished product packaging delivery shall be fully automated assembly line operation and management mode, supplemented by manual sampling and review system to jointly build a solid defense line to protect the bottom line of product quality from infringement. Including but not limited to ultrasonic thickness gauge to monitor the uniform distribution of wall thickness, X-ray fluorescence detector to identify potential crack defects and other key node monitoring means.
