Renault
China Renault Truck Parts Manufacturer & Supplier
OEM-Grade Renault Truck Parts — Gearbox & Engine Components
Mide-Diesel Technology & Parts Co., Ltd. is a China-based Renault truck parts manufacturer and supplier serving workshops, fleet operators, and parts distributors across the heavy-duty truck aftermarket. As a factory-direct supplier, we design, machine, test and export Renault replacement parts across two core product families — Gearbox and Engine — supported by an in-house engineering team, CNC production capability, and a stocked inventory of over 10,000 independent SKUs across major European truck brands, including shared-platform coverage for Renault, Volvo and RVI components where OE part numbers overlap.
Why Choose Mide-Diesel as Your Renault Parts Manufacturer
Sourcing Renault truck parts from a Chinese supplier carries real risk if that supplier cannot demonstrate manufacturing capability, dimensional accuracy, and consistent export experience. We built our factory and catalogue specifically to remove that risk for B2B buyers.
Factory-Direct Manufacturing, Not TradingUnlike trading companies that resell parts sourced from unverified third-party workshops, Mide-Diesel operates as a manufacturer and supplier with our own CNC machining lines and testing equipment. This gives us tighter tolerance control on gearbox housings and engine-related components, shorter lead times on bulk or custom orders, and a single point of accountability for quality — exactly what a wholesale buyer needs before committing to a container order of Renault parts. |
A Team Built Around Truck Parts EngineeringOur production and R&D team of 50 specialists covers product design, reverse-engineering from OE samples, tooling, and quality verification. Every Renault part we introduce — whether a gearbox housing, control valve, or sensor — is checked dimensionally against OE reference samples before entering our catalogue. This is why fleet workshops and distributors treat our Renault parts range as a dependable OEM-equivalent source rather than a generic aftermarket gamble. |
Inventory Depth for Wholesale & Bulk OrdersWith more than 10,000 SKUs in stock across Volvo, Scania, Renault, Mercedes-Benz, DAF, MAN, Iveco and other European truck brands, we support both single-container wholesale orders and ongoing distributor supply agreements. Because Renault, RVI and Volvo heavy trucks frequently share OE part numbers due to their shared corporate platform history, buyers sourcing Renault components can often consolidate related Volvo-compatible parts into the same order — reducing supplier fragmentation for multi-brand fleets. |
Renault Parts Categories We Manufacture and Supply
Our Renault catalogue is organized into two core categories, each linking to detailed sub-pages listing individual part numbers, OE cross-references and technical specifications.

⚙️
1. Renault Gearbox PartsThe gearbox is one of the highest-value, highest-consequence systems on a heavy-duty truck, and gearbox-related failures are among the most expensive downtime events a fleet can experience. Our Gearbox range includes gearbox housings, control valves, gasket kits and related transmission-system hardware engineered to match Renault's OE tolerances for fitment, sealing, and pressure handling. Because gearbox components must withstand continuous mechanical load and pressure cycling, we manufacture and test these parts against strict dimensional and pressure specifications. Wholesale buyers can source complete housing-and-valve assemblies or individual parts, with OE and cross-brand (Renault/Volvo) part number cross-referencing provided on request. Read More |

2. Renault Engine PartsOur Engine category covers the components that directly affect drivability, throttle response and engine-management accuracy — including the accelerator pedal sensor, gear shift lever knobs, air pressure pipes, steering wheel sensors, ABS sensors, and complete engine assemblies. These are precision components where dimensional accuracy and electronic signal integrity directly affect throttle response, fuel efficiency, and emissions behavior. Each engine-related electronic component is manufactured using specified materials such as Polyamide 6 housings with defined connector types and terminal counts to ensure plug-in compatibility without rewiring, directly reducing field return rates and comeback repairs.

Featured Best-Selling Renault Parts
Beyond the Gearbox and Engine categories, these are the components our B2B customers reorder most consistently — spanning braking, throttle control and wear-monitoring systems.
| Part Name | Function | Key Specifications |
|---|---|---|
| Control Valve | A critical component in the trailer braking system, regulating air pressure between the tractor and trailer to maintain balanced brake response — especially important on heavy-load vehicles. | Calculated volume: 3.55 dm³ Max operating pressure: 8.0 bar Temperature range: -40°C to +80°C Cross-ref: Renault 74 21/74 23 series & Volvo OE |
| Accelerator Pedal Sensor | Sends electronic signal to the engine/powertrain control module (ECM/PCM) indicating pedal position; the core input in drive-by-wire throttle systems with no mechanical cable. | Housing: Polyamide 6 Connector: Female oval plug-in Terminals: 6-terminal male Fitment: Direct bolt-on, no rewiring |
| Brake Caliper Wear Sensor | Monitors brake pad wear and alerts the driver when replacement is needed, with separate front-axle and rear-axle sensor placement. A direct safety and maintenance-scheduling tool for fleet operators. | Front & rear axle variants OE cross-reference available Fitment: Direct replacement |
Manufacturing Quality and Testing Process
As a manufacturer and supplier — not a reseller — we control the full production chain for the majority of our Renault parts, applying consistent quality checkpoints across the Gearbox and Engine categories:
- OE sample cross-referencing during product development to confirm dimensional and functional match, including shared Renault/Volvo/RVI part numbering.
- CNC-machined tooling for gearbox housings and pressure-rated components such as control valves.
- Pressure and temperature-range testing for pneumatic and hydraulic components.
- Electrical and connector-fitment verification for sensors, including the accelerator pedal sensor and ABS sensor.
- Pre-shipment inspection to confirm packaging integrity for long-distance sea and rail freight.
How B2B Buyers Work With Us
Ordering Process
|
Packaging and ShippingParts are packaged in plastic bag, carton, or wooden box formats depending on part size and fragility. We support road, rail, sea and air transport — allowing distributors and wholesalers to select the shipping method that fits their cost and lead-time requirements, from single-pallet air shipments to full-container sea freight for large wholesale orders. Support Throughout the RelationshipOur service model is structured around three stages: pre-sales support to help buyers identify the correct part or cross-reference, in-sales support covering quality control and shipping execution, and after-sales support through a 24-hour service line for fitment questions or order issues. |
Frequently Asked Questions
| What does a control valve do? | The control valve works with other braking-system components to regulate air pressure between the tractor and trailer, helping the vehicle maintain balanced, consistent braking performance, particularly under heavy load. |
| What is the reference voltage of an accelerator pedal sensor? | Each potentiometer in the sensor has three electrical circuits: a 5-volt reference circuit that supplies voltage to the sensor, a signal voltage circuit to the ECM/PCM, and a ground circuit. Resistance across the circuit varies with pedal position. |
| What is the purpose of an accelerator pedal sensor? | It registers the movement and position of the accelerator pedal, and the engine management system uses that signal — output in analog or digital form — to calculate the torque the driver is requesting. |
| Do you supply wholesale and distributor-volume orders? | Yes. As a manufacturer and supplier with over 10,000 SKUs in stock, we support both single-part sampling orders and full-container wholesale orders, with MOQ and pricing tiers confirmed at quotation stage based on part category and order volume. |
| Can you cross-reference Renault parts by OE number? | Yes. Because many Renault, RVI and Volvo heavy-truck components share OE part numbering, send us the OE number, Renault part number, or vehicle model and year, and our team will confirm the matching part from our Gearbox or Engine catalogue. |
