SINO CHOICE | On May 13,2026,30 core components from Sinotruk and Shaanxi Auto officially launched!
—from the engine heart to the vehicle armor, all-in-one solution with quality assurance worldwide!
On May 13,2026, the warehouse of SINO CHOICE was bustling with activity. After weeks of meticulous preparation by the procurement team and rigorous inspection by the quality control team on each item, a shipment of core components from Sinotruk and Shaanqi (covering 30 product categories) was successfully loaded onto trucks and was about to embark on its overseas journey.
This is no ordinary shipment; it represents SINO CHOICE's renewed commitment to quality for global customers. From the engine's "heart" to the transmission system's "skeleton," from the chassis suspension's "joints" to the vehicle's exterior "armor" —each of the 30 carefully selected components meets stringent standards and covers all critical vehicle systems, delivering true "one-stop integration."
Today, let's unveil these "star accessories" one by one, while providing you with an in-depth look at SINO CHOICE—a leading company with seventeen years of expertise in the international heavy-duty truck parts market—and exploring what has earned it unanimous acclaim from clients worldwide.
1. Today's shipment: 30 core components covering the vehicle's five major systems. These 30 components can be categorized by function into five sections: engine system, transmission system, chassis suspension system, body and electrical system, and hydraulic/pneumatic system, encompassing nearly all critical components of heavy-duty trucks.
🔥 Section 1: Engine Core Components (10 Models) – The "Heart" of the Vehicle. As the power source for heavy-duty trucks, engines constitute the largest proportion of components in this shipment, highlighting SINO CHOICE's high priority placed on powertrain systems.
| No. | Part Name | Detailed Description |  | --- | --- | --- |  | 1 | Cylinder Liner | The engine's "trunk," directly enduring the friction and high temperatures from the piston's reciprocating motion. The cylinder liner supplied by SINO CHOICE is made of high-quality alloy cast iron with exceptional wear resistance, featuring a precision ground inner surface that ensures optimal fit with piston rings, significantly extending the engine's service life. |
The two-link assembly (including the connecting rod bush) is one of the most critical moving components inside the engine, converting the piston's reciprocating motion into the crankshaft's rotational motion. SINO CHOICE's connecting rod assembly employs high-strength forged steel, with connecting rod bush precision reaching the micron level, ensuring perfect fit with the crankshaft journal to minimize wear and reduce noise.
The "main shaft" of the three-crankshaft engine collects and delivers power from all cylinders. The crankshaft assembly provided by SINO CHOICE undergoes precision dynamic balancing calibration, ensuring smooth operation with minimal vibration—a fundamental guarantee for the engine's long-lasting and efficient performance.
4. The camshaft serves as the "commander" controlling valve operation, directly influencing the engine's intake and exhaust efficiency. SINO CHOICE's camshaft is constructed from high-quality alloy steel with precise cam profiles, ensuring accurate valve timing and enhanced power delivery.
5. The high-pressure oil pump serves as the "blood supply station" in the diesel common rail system, pressurizing fuel to extremely high pressure before delivering it to the injectors. SINO CHOICE's high-pressure oil pump delivers stable pressure and rapid response, ensuring optimal fuel atomization, more complete combustion, and lower emissions.
The oil transfer pump serves as the "transporter" that delivers fuel from the tank to the high-pressure oil pump. The pump selected by SINO CHOICE features stable flow rate and strong self-priming capability, enabling rapid fuel supply even in low-temperature environments.
The core precision components inside the 7-plunger high-pressure oil pump work in conjunction with the plunger sleeve to form a sealed chamber that generates high pressure. The plunger of SINO CHOICE is manufactured through high-precision grinding, offering exceptional sealing performance, high-pressure resistance, and wear resistance.
The 8-injector system delivers high-pressure fuel precisely to the cylinder's "terminal actuators," directly determining combustion efficiency. The injectors supplied by SINO CHOICE deliver uniform injection pressure and fine atomized fuel particles, effectively enhancing power output while reducing fuel consumption.
The 9-cylinder head gasket serves as the sealing barrier between the cylinder head and cylinder block. SINO CHOICE employs a multi-layer steel plate composite structure, offering exceptional resistance to high temperatures and pressures while ensuring superior sealing performance, effectively eliminating the three major risks of air, water, and oil leakage.
10. Middle Gasket for Pump: The sealing gasket between the pump and the cylinder body, though small in size, is critically important. The gaskets supplied by SINO CHOICE feature high-quality materials and precise dimensions, ensuring a leak-proof cooling system seal and consistently controlled engine temperature.
SINO CHOICE offers a comprehensive range of ten engine components—from cylinder liners and crankshafts to oil pumps and fuel injectors—covering all essential engine parts. Whether for major overhauls or routine replacement of wear-prone components, this product line meets all core operational requirements.
Section 2: Transmission System Components (6 Models) – The "Bridge" of Power Transmission   | Serial Number | Component Name | Detailed Description |   |------|---------|-------------------|   | 11 | Driven Disc Assembly | The core component of the clutch system, responsible for power engagement and disengagement between the engine and transmission. SINO CHOICE's driven disc assembly features wear-resistant friction pads and durable shock absorbers, ensuring smooth shifting without slipping.
12 The flywheel housing serves as the "bridge" connecting the engine and transmission, while also functioning as the mounting base for the starter motor. SINO CHOICE's flywheel housing features precision casting and high strength, ensuring stable and reliable power delivery.
The 13-tooth face gear flange assembly serves as the connecting component between the drive shaft and the transmission/drive axle, employing a face gear transmission system that offers high load-bearing capacity and efficient power transmission, making it a reliable choice for heavy-duty trucks operating under demanding conditions.
The "joint" of the 140,000-piece universal joint drive shaft enables torque transmission at various angles. SINO CHOICE's universal joint cross shaft features wear-resistant needle roller bearings, ensuring smooth and lag-free rotation suitable for diverse challenging road conditions.
The damping element in the 15-torque rubber core transmission system absorbs torsional vibrations between the engine and the transmission. SINO CHOICE employs a composite structure of high-quality natural rubber and a metal frame, offering excellent elasticity and long service life to effectively protect the transmission system.
The 16-bolt power take-off assembly extracts engine power from the transmission side to drive auxiliary equipment such as hydraulic pumps and air compressors. The SINO CHOICE power take-off assembly ensures smooth shifting and stable output, making it an essential component for specialized vehicles like dump trucks and mixer trucks.
With six transmission components—from the clutch and universal joint to the flywheel housing and transfer case—SINO CHOICE ensures precise power delivery from the engine to every wheel.
