Skyond from China manufactures and supplies a variety of heavy-duty truck components with over 15 years of experience serving the commercial vehicle aftermarket and wholesale sector. In Sinotruk Parts whole series, Sinotruk Chassis Parts form the structural foundation that determines vehicle load capacity, stability, and safety. We also supply complementary product lines such as Sinotruk Cabin Parts and transmission components, enabling fleet operators and repair workshops to source across multiple vehicle systems from a single supplier. Products are exported worldwide to Russia, Africa, Southeast Asia, Central Asia, and beyond. Our manufacturing facilities are certified to IATF 16949, ISO 9001:2015, and ISO 14001, confirming our quality management systems and environmental compliance meet international standards.
Sinotruk Chassis Parts are engineered to withstand the extreme demands of heavy-duty trucking constant vibration, heavy payloads, corrosive road conditions, and millions of stress cycles. Skyond's Sinotruk Chassis Parts are manufactured from high-strength materials including 550L grade steel with tensile strength exceeding 550 MPa, with zinc-nickel electroplating and passivation treatment achieving salt spray resistance exceeding 480 hours. Every structural component is produced with robotic welding and CNC machining, with 100% dimensional inspection before shipment. Whether you need frame crossmembers for structural integrity, brake drums for stopping power, or suspension components for load stability, Skyond's Sinotruk Chassis Parts deliver the durability and precision that heavy-duty operations require.
Product Advantages
1. High-Strength Materials for Reliable Load Capacity
Chassis structural components including frame crossmembers and bending beams are manufactured from 550L grade high-strength steel with tensile strength exceeding 550 MPa. This material grade provides the bending and torsional resistance required for heavy-duty trucks operating under maximum payloads and poor road conditions, ensuring the frame structure remains stable and free from deformation over the vehicle's service life.
2. Superior Corrosion Protection for Harsh Environments
Critical metal components receive zinc-nickel electroplating plus passivation treatment, achieving salt spray resistance exceeding 480 hours. This dual-layer protection effectively resists corrosion from moisture, salt, mud, and sand extending the service life of chassis components in coastal regions and areas where road de-icing salts are used.
3. Durable Braking System Components
Brake drums and brake shoes are manufactured from wear-resistant materials using precision casting processes. The design ensures stable braking performance and effective heat dissipation, meeting the safety and durability requirements of frequent braking conditions common in mining and heavy haulage operations.
4. OEM Fitment for Accurate Installation
Brackets, mounting components, and connectors are produced to original Sinotruk dimensional specifications. Mounting holes align with the frame with 100% accuracy, allowing direct replacement without modification saving workshop installation time and eliminating the risk of improper fitment.
5. Lightweight Design Balancing Strength and Weight
Through roll forming processes and optimised cross-section design, certain structural components achieve reduced weight while maintaining load capacity. This contributes to lower overall vehicle fuel consumption without compromising structural integrity.
6. Full Process Quality Control with Traceability
Key structural components undergo CNC drilling and 100% dimensional inspection. Manufacturing facilities are IATF 16949 and ISO 9001:2015 certified, with certain components carrying traceability markings for quality verification and accountability.
7. Comprehensive Coverage for All Major Truck Models
Components are available for HOWO, HOWO A7, T7H, SITRAK C7H, and other full-series models, with configurations to suit different chassis layouts including 4×2, 6×4, and 8×4.

Process Requirements
Structural components such as bending beams are manufactured from 550L grade high-strength steel with tensile strength ≥550 MPa. Production processes include roll forming, CNC drilling, and deburring, with 100% dimensional inspection to verify accuracy.
Corrosion protection. Zinc-nickel electroplating (8μm thickness) plus passivation treatment achieves salt spray resistance of 480 hours, providing reliable protection against environmental corrosion.
Certifications. Manufacturing facilities are certified to IATF 16949, ISO 9001:2015, and ECE R55 standards.
Installation specifications. M12 bolts require 200 N·m torque with thread locking compound applied during installation.
OEM Customisation Services
Skyond offers comprehensive OEM customisation services for chassis components to meet specific fleet requirements. Beyond standard replacement parts, we can manufacture components according to customer technical drawings or physical samples. Common customisation requests include:
Reinforced leaf springs for extra-heavy payload applications
Specialised mounting brackets for custom truck bodies or equipment installations
Modified frame brackets with unique hole patterns or dimensions
Corrosion-resistant coatings beyond standard specifications
Our engineering team works closely with customers to develop parts that meet exact material and dimensional specifications. A full-cycle service from initial prototyping to large-scale production ensures custom chassis solutions are delivered with the same quality and reliability as our standard inventory.
Customisation process:
Customer provides drawings, samples, or specifications
Engineering review and design optimisation
Sample fabrication and customer approval
Batch production with full quality control
Shipping with documentation
Why Work with Skyond?
1. chassis components carry the entire vehicle load. Inferior parts compromise safety and shorten vehicle life. Skyond chassis parts are manufactured from 550L grade steel, not lower-grade alternatives. The material selection is non-negotiable.
2. 480 hours salt spray resistance means these components survive on roads where de-icing salts are used, and in coastal environments. We don't cut corners on surface treatment.
3. Frame brackets, suspension components, brake drums, and hubs are maintained in stock. Most confirmed orders ship within 6-7 days.
4. A suspension repair may need brackets, bushings, and bolts. A brake service may need drums, shoes, and chambers. We supply the full set of associated components — reducing your need to chase multiple suppliers.
5. 12-month warranty on manufacturing defects. If a quality issue arises, we repair, replace, or refund.
FAQ
Q1: How do I know the right chassis parts for my vehicle?
Provide your vehicle model, chassis configuration (4×2, 6×4, or 8×4), and the original part number if available. Our technical team can verify compatibility and confirm the correct components.
Q2: What is the advantage of 550L grade steel?
550L grade steel offers tensile strength exceeding 550 MPa, providing the structural strength required for heavy loads and rough road conditions while maintaining adequate ductility to resist fatigue cracking.
Q3: How does the corrosion protection system work?
Components receive zinc-nickel electroplating (8μm thickness) followed by passivation treatment, achieving 480 hours salt spray resistance. This dual-layer protection provides long-term corrosion resistance in demanding environments.
Q4: Do you supply custom chassis components for non-standard applications?
Yes. We manufacture components to customer drawings or specifications. Provide technical drawings or physical samples, and our engineering team can produce custom parts.
Q5: Should I replace suspension components in pairs?
We recommend replacing suspension components in pairs (left and right) to maintain balanced vehicle handling and even wear. Individual replacement may cause handling differences.
