Explore our premium range of precision multi-function dashboards and sensor kits manufactured directly at our standard automotive meter factory.
Modern off-road and rally competition environments present some of the most punishing environments for electronic equipment. In these extreme conditions, typical OEM dashboards fail due to high vibration, heavy moisture, extreme dust ingress, and poor readability under bright sunlight. As a result, the global motorsport industry has rapidly transitioned toward ruggedized digital telemetry hubs and integrated rally race dash kits.
Key technological shifts currently defining the manufacturing landscape include:
A premier global manufacturer of advanced automotive instrumentation, tuning solutions, and high-performance racing gauge panels.
Established in 1986, Ruian DongOu Automobile Meter Factory is a highly specialized, professional enterprise dedicated to the research, development, and mass production of premium automotive instrumentation systems. Over the course of 38+ years, we have built a complete vertical technical manufacturing process, featuring precision SMT lines, automated sensor calibration, and thorough environmental stress testing laboratories.
To address different segments of the market, DongOu operates through two specialized brands:
Developed in close cooperation with an Australian automotive engineering partner. SincoTech focuses exclusively on professional motorsport dashboards. By maintaining highly stringent R&D standards, its products deliver extreme accuracy, sub-millisecond response rates, and reliable performance in high-stakes racing scenarios.
Dedicated to custom car culture and performance modifications. GragonGauge features analog and digital-hybrid devices covering boost levels, vacuum, water temp, oil temperature, oil pressure, battery voltage, air-fuel ratios, exhaust gas temperature (EGT), and shift warning indicators. These units are available in standard 52mm (2 inches), 60mm (2.36 inches), and 85mm (3.75 inches) sizes to seamlessly fit custom pods.
Providing high-precision hardware, global compliance parameters, and deep customization capabilities for international B2B buyers.
Our dedicated R&D team features engineers specializing in mechanical integration, microcontroller firmware, and telemetry interfaces to design instruments that communicate flawlessly with modern OBD-II and standalone engine ECUs.
Every rally race dashboard undergoes intense verification including thermal chamber profiling (-20°C to +80°C), physical drop tests, and simulated mechanical vibration sweeps to guarantee compliance in off-road terrains.
We provide full customization of dial layouts, backlight illumination colors, sensor thread configurations (NPT/PT), display measurement units (metric/imperial), and direct integration of corporate client branding on the start-screen firmware.
How international tuning shops, specialized vehicle builders, and commercial fleets configure and apply our instrument technology.
Global wholesale buyers typically source dashboards and standalone modules for three core use cases:
Modified tuners use our high-accuracy 52mm and 60mm gauges (volts, water temp, oil temp, boost) housed in single A-pillar pods or dashboard center consoles to monitor modified engine states.
Professional circuit race and rally vehicles utilize integrated multi-function screens (e.g. DO908 waterproof series) to display up to 18 distinct parameters like RPM, fuel pressure, exhaust temp, and boost values on a single display.
Our universal mounting brackets and standard sizes mean dashes can be positioned securely in any orientation, satisfying custom dashboard fabrication setups in kit cars, classic restomods, or specialized utility vehicles.
Looking toward future innovation in vehicle electronics and ensuring international import compatibility.
Improving dashboard compatibility with high-speed CAN-FD data protocols used in the newest performance cars, maintaining latency under 5 milliseconds.
Transitioning to specialized automotive-grade OLED panels featuring auto-dimming sensors to ensure optimal visibility in open sunlight and late-night conditions.
Developing secure Bluetooth-enabled engine bay transmitter hubs to stream fluid pressure and temperature data directly to the dashboard, reducing cabin wiring complexity.
All instruments developed at our Ruian DongOu Automobile Meter Factory are manufactured to strict quality regulations. We perform multi-stage SMT verification, individual calibration for every sensor sender (1/8 NPT, pressure transducers, thermocouple connections), and secure export packaging. Our experienced logistics division coordinates direct shipping channels to key markets in North America, Western Europe, Southeast Asia, and Australia, providing proper customs documentation, product compliance certificates, and technical manuals.
Answering common technical, ordering, and logistics questions from professional motorsport suppliers and distributors.
Our SincoTech dashboards (such as DO908 and DO921) support both raw analog sensor inputs (via the included connection harness/sensor kit) and OBD-II standard protocols. They are compatible with ISO9141-2, ISO14230-4, ISO15765-4 CAN, and SAE J1850 protocols, making them universally adaptable to most vehicles produced since 1996.
Yes. As an original OEM/ODM factory, Ruian DongOu provides customization services. We can print your brand logo on the physical housing of the gauges and modify the device start-up logo within the firmware. Please contact our sales team to discuss minimum order requirements (MOQ) for custom firmware modifications.
Our SincoTech DO908 series features a rugged IP65-sealed structure designed to withstand water splashes, heavy mud, and intense humidity typical of rally environments. However, direct high-pressure jet washing should be avoided to protect the wiring harness seals.
We supply three industry-standard sizes: 52mm (2 inches), 60mm (2.36 inches), and 85mm (3.75 inches). This comprehensive sizing allows compatibility with almost any standard pillar pod, dash plate, or customized instrument cluster panel on the market.
Yes. Our retail and wholesale kits include all corresponding high-grade sensor units (water temperature senders, oil pressure senders, fuel level float sensors, and EGT thermocouple probes where applicable) with matching thread types (typically 1/8 NPT), wire harnesses, and mounting hardware.
Select from our widely distributed modification gauges, multi-function tachometers, and specialized sensors.
