Explore our flagship multi-functional racing and custom digital dash systems designed for modern performance and retro configurations.
Established in 1986, Ruian DongOu Automobile Meter Factory (widely known as DongOu) has remained a global frontrunner in the specialized research, development, and high-precision manufacturing of automotive instrumentation systems. With over 38 years of dedicated engineering evolution, our production unit has established a mature technical ecosystem that successfully supplies custom solutions to the racing, retro-fitting, and classic car conversion markets worldwide.
Our company manages a versatile design and manufacturing pipeline through two distinct global brands, targeting specific industry segments with absolute technical precision:
Bridging the gap between analog classic aesthetics and next-generation CAN-bus telemetry.
From 52mm, 60mm, to 85mm analog pods to fully integrated wide-aspect LCD modules, our engineering team tailors casing depths, bezel styles, and mounting brackets for seamless classic vehicle retrofits.
We specialize in bridge solutions that convert analog pressure and temperature sensors (resistive/voltage-based) into digital protocols while simultaneously harvesting modern OBDII and Bluetooth CAN data streams.
Our instrumentation runs through rigorous laboratory thermal chambers, vibration stress-testing rigs, and strict EMI shielding reviews to guarantee durability across classic car restomods and racing conditions.
A B2B perspective on balancing vintage aesthetics with modern vehicle electronics integration.
Historically, vintage instrumentation relied on direct mechanical cables (for speedometers) and thermal/bi-metallic voltage-drop sensors (for oil pressure and coolant temperature). When executing a restomod project—retrofitting high-performance engines such as LS, Coyote, or K-Series crates—the mechanical legacy systems conflict with the modern Electronic Control Unit (ECU).
Our engineering approach bridges this divide. The SincoTech and GragonGauge digital units act as hardware and firmware translation matrices. Through customizable sensor arrays and OBDII Bluetooth links, we extract precise RPM, EGT, fuel level, and pressure data directly, displaying it with low-latency responsiveness.
Classic car cockpits are often subjected to direct sunlight, causing extreme glare. To address this, we leverage two advanced display methodologies:
Used in our DO907 and DO908 series, OLED technology yields an emissive display where individual pixels emit light. This yields an infinite contrast ratio, deep blacks, and a wide viewing angle, critical for vintage dashboards with angular geometry.
For classic racers seeking analog-digital hybrids, our DO921 and DO922 platforms utilize transflective LCD technology. This design reflects ambient light, making it highly readable under direct sunlight while drawing minimal electrical currents.
The future of classic digital dash design lies in seamless, multi-protocol integration. As global emissions standards tighten, classic cars are increasingly being converted to electric vehicles (EV Restomods). Ruian DongOu is actively designing custom digital gauge configurations to monitor high-voltage battery health, state of charge (SoC), thermal management, and electric motor RPM alongside traditional pressure and speed telemetry.
Our development roadmap is centered around deep diagnostic intelligence. Future product rollouts will feature custom-designed mobile applications allowing restomod workshops to reprogram warning thresholds, screen colors, and sensor curves via Bluetooth, reducing dependencies on physical setup buttons.
Providing custom dashboard arrays for racing, tuning, and classic restorations globally.
Operating from Ruian, the cluster capital of automotive electronics in China, DongOu Meter Factory utilizes a vertically integrated supply chain system. By containing critical manufacturing steps—such as SMT assembly, injection molding, CNC machining, calibration, and environmental testing—within our own factory walls, we eliminate key supply chain bottlenecks.
This integrated approach allows us to deliver substantial cost advantages and high quality control directly to global distributors:
Ensuring seamless import and regulatory approvals for worldwide B2B operations.
Classic cars feature older, less-insulated ignition wires, which can generate severe electromagnetic interference. Our digital dashboards are designed with dedicated metal shield jackets and integrated filtering capacitors to prevent signal noise or screen flicker.
All materials—from plastics to PCB components—adhere strictly to CE and RoHS standards. We facilitate direct custom packaging and labeling, ensuring that regional importers face no regulatory friction at customs.
For large-scale restomod enterprises, hot rod builders, and niche performance brands, we offer tailored startup screens, physical logo prints, customizable housing textures, and unique sensor configurations.
Technical guidance and commercial purchasing policies for classic car restomod distributors.
Yes. While our platforms integrate seamlessly via OBDII protocols for post-1996 vehicles, we also supply comprehensive analog sensor kits. These kits feed analog oil pressure, water temperature, fuel level, and speed data directly into the dashboard converter chip. This allows compatibility with older carburated engines.
Yes. Ruian DongOu Automobile Meter Factory provides end-to-end OEM and ODM branding options. We can customize startup screen logos, housing screen-prints, packaging boxes, and build custom bezels. Minimum Order Quantities (MOQ) vary depending on customization levels.
Our high-end SincoTech racing dashboards feature anti-glare screen treatments and high-luminance backlight settings. Our GragonGauge series relies on high-contrast OLED and transflective LCD designs. This allows clean, legible readings in convertibles and open-cockpit vintage cars.
All our dashboards and individual gauges are optimized for standard 12V automotive electrical systems. They feature internal voltage regulation to guard against voltage spikes and battery charging fluctuation.
Our products comply with CE, FCC, and RoHS directives, making them compliant for retail and installation markets throughout North America, Europe, and Australia.
Engineered to deliver high accuracy and fast refresh rates across varying track environments.
