Yin-Ching machines shell cases for mono-tube shock absorbers for cars. These tubes can be used in shock absorbers for street and circuit racing. Our high-quality tubes have smooth inner diameters and ensure smooth movement in the shock absorber chamber and proper regulation of damping force. We also provide customization services, for example, different color coatings, internal/external threaded machining, and stepped outer diameters.

A piston rod is a pivotal component in a shock absorber and a strut. It should deliver the ideal amount of liquid to the seal, reducing the seal’s wear and tear and minimizing the leaking possibility.

Ying-Ching’s piston rods have a high-quality finish and are corrosion- and wear-resistant. They sustain the shock absorber’s frequent movement and ensure durability.

The functions of a strut housing are to support a strut assembly and provide a connection with the steering knuckle. Our strut housings are made of carbon steel and, therefore rust free and very durable. Our machining can also process other car suspension parts such as pipes for brackets and torsion beams.

We produce strut housings for both right and left wheels and provide made-to-order services for shock absorber manufacturers and auto part dealers for the auto aftermarket.
