Precision drive to ensure the coordinated operation of every link of the engine
This timing chain effectively regulates the various stages of the engine through precise cooperation with the camshaft and oil pump, ensuring the orderly advancement of the intake, compression, combustion and exhaust processes, making the power system run more smoothly and reliably.
Adapt to high-output, small-volume engine structure
The product is specially designed for high-performance compact engines to achieve stable drive in limited space. It has good tensile strength and wear resistance, can adapt to high-load conditions for a long time, and is an ideal choice for the new generation of automotive power systems.
Durable and quiet, suitable for modern vehicle applications
The selection of high-grade materials and combined with special surface treatment technology greatly improves the chain’s fatigue resistance and service life. While ensuring durability, it effectively reduces operating noise to meet the high requirements of modern cars for quietness.

Frequently Asked Question
Our design uses special materials and treatments that lower friction, making the engine quieter.
We pioneered the use of a 6.35mm pitch silent chain in small car engines—quiet, strong, and reliable.
It fits into smaller engine spaces and still handles high power without wearing out quickly.
Thanks to smart design and treated surfaces, the chain moves more quietly, which helps lower overall engine sound.
We were the first to use a 6.35mm silent chain in small car engines—it’s a big step forward in noise control and reliability.
The treatment makes the chain tougher. It fights off rust, reduces friction, and helps it last longer under stress.
