The global motorsport landscape and custom tuning sectors are undergoing a significant shift from traditional analog needles to digital telemetry displays. Professional racing teams, custom vehicle builders, and automotive modification companies require reliable, real-time data visualizations to make split-second decisions. A single failure in tracking engine vitals—such as oil temperature, boost level, air-fuel ratio, or water temperature—can result in catastrophic powertrain damage. Consequently, B2B procurement professionals look for high-tier suppliers capable of delivering precision, reliability, and custom-engineered dashboard kits.
Procuring custom race dash panels is no longer just a purchasing decision; it is a critical engineering partnership. Global industrial vehicle builders, performance tuning shops, and off-road defense groups demand solutions that support robust protocols (such as OBDII or high-speed CAN-bus) while surviving harsh operational environments. From dust-filled rally stages in South America to vibration-heavy offshore racing in Northern Europe, the dashboard must remain perfectly readable, fully integrated, and waterproof.
Welcome to learn about our company. Established in 1986, Ruian DongOu Automobile Meter Factory is a professional enterprise dedicated to the research, development, and production of high-performance automotive instrumentation systems. Over nearly four decades of dedication, our factory has cultivated deep expertise, building a mature, complete technical ecosystem and highly stable production capabilities. We have established a strong reputation in the global field of automotive instrumentation.
Whether serving high-end professional racing circles through our partner brand SincoTech or supplying street tuners with GragonGauge, we pride ourselves on delivering field-tested telemetry systems. Through our joint venture R&D efforts with Australian specialists, we ensure that our engineering standards continuously meet or exceed international expectations.
At Ruian DongOu, we engineer dashboards to withstand extreme temperatures, G-forces, and humidity. Our flagship brand, SincoTech, focuses on high-end racing applications. Developed in partnership with an Australian engineering firm, it combines top-tier hardware durability with proprietary data processing algorithms.
For street performance and extensive customization, our GragonGauge brand covers an extensive lineup of tachometers, boost gauges, vacuum gauges, water temperature gauges, oil temperature gauges, oil pressure gauges, voltmeters, air-fuel ratio gauges, and exhaust gas temperature (EGT) meters. These are provided in standardized dimensions of 52mm (2 inches), 60mm (2.36 inches), and 85mm (3.75 inches) to ensure seamless drops into custom instrument pods and factory gauge clusters.

One size does not fit all in the world of high-performance automotive cockpits. Ruian DongOu offers end-to-end OEM and ODM customization services. As an established manufacturer, we accommodate custom branding requests, unique gauge ranges, modified alarm thresholds, and custom wiring configurations.
Whether you are an overseas distributor wanting to build your private label brand, or a boutique supercar manufacturer needing a bespoke interface, our R&D department provides the direct support you need.
We support private-label branding, customized startup logo screens, and bespoke dial designs for all single and multi-function dashboards.
Adapt tachometer limits (up to 11000 RPM), adjust measurement ranges (Celsius vs Fahrenheit), and fine-tune critical alarm flashing thresholds.
We provide aluminum brackets, dash-top pods, and low-profile housings suited for diverse layouts (52mm, 60mm, and 85mm specifications).
Reliability on the track must be matched by reliability in the supply chain. Ruian DongOu distributes its product range to over 50 countries, including North America, Australia, the European Union, and Southeast Asia. We ensure fast, secure international freight and customs clearances.
Our manufacturing facility operates under strict quality management frameworks, carrying out rigorous stress testing on vibration tables and thermal shock chambers. Every batch undergoes calibration against reference sensors to guarantee that the displays in racing cockpits show real-time metrics with zero lag.
We work closely with global import compliance agencies. Our hardware complies with standard EMC parameters, limiting electromagnetic interference with sensitive onboard electronic control units (ECUs). Additionally, our engineering teams provide remote diagnostic support, wiring guides, and firmware updates for all digital dash models, ensuring that local installers can easily wire and configure our products.
Yes. Our multi-function racing dashboards connect through a standalone high-precision sensor control box or directly to the vehicle's OBDII OBD2 port. For standalone custom project builds, the gauges can run entirely off our dedicated sensor kits, rendering them independent of any specific aftermarket ECU brand.
The primary difference lies in the air-fuel ratio (AFR) telemetry. The DO926NB is designed for standard narrowband monitoring interfaces, while the DO926WB includes an advanced oxygen sensor controller, making it suitable for tuning setups that require real-time wideband AFR analysis for dynamic fuel map scaling.
The DO908 dashboard features an internally sealed housing and waterproof connectors, certified to prevent water ingress from splashing, rain, and mud. This makes it highly suitable for open-cabin race vehicles, rally cars, off-road buggies, and marine applications.
For qualifying wholesale and OEM/ODM buyers, we can customize the hardware dimensions, startup splash screens with your corporate logo, scale parameters, and warning light triggers. We also offer customization for specific wire loom lengths and specialized mounting frames.
No. The 85mm GPS speedometer features a high-sensitivity GPS antenna that calculates ground speed via satellite triangulation. This bypasses the need for mechanical gearbox speed cables or wheel speed sensors, making it ideal for custom conversions, hybrid projects, and EV motor swaps.
