Professional Research and Development Team

TGQ is fully committed to investing in development capabilities to achieve excellence in production processes and products. We as an expert in producing parts of suspension and steering systems, including control arm, ball joint, bushing, stabilizer link, tie rod end, and rack end.

In the early days of its establishment, TGQ strived for a chance to cooperate with the top three original parts and aftermarket manufacturers in USA. It is challenging to be an extremely demanding OEM factory, which others would rather avoid doing, and get new product development opportunities to create market differentiation.

Real-Time Operating, Compliance with Regulations, Precision and Pragmatism

TGQ fully implies the work rules of “Real-time operating, compliance with regulations, precision, and pragmatism.” Now, it ranks among the top three in the aftermarket chassis and steering industry in Taiwan and become a Tier 2 supplier of well-known automotive manufacturers in Europe and a Tier 1 supplier of German EV.

Besides, TGQ is also the core supplier of leading brands in the region and offers our products and services to the most well-known brands worldwide aftermarket. Behind the lean manufacturing process of the parts, TGQ gained a lot of professional production experience, which complies with OE’s strict product specifications and rigorous drawing requirements.

It does improve our manufacturing technology and enhance the quality control standards; the most important thing is to establish the quality of TGQ basis.

Professional Technical Team

TGQ has a professional technical team (stamping process, welding process, cutting process, rubber process, assembling process), standardized production process, strict quality and environmental standards (with ISO9001 international quality certification, IATF16949, ISO14001 environment Management system certification).

In addition to the research and development department and production of automotive chassis suspension system spare parts, it can also create customized products for customers.
