Dongfeng GX Front suspension right end fixed bracket 2901249-H02C1

The bracket features a multi-ribbed reinforced structure optimized for maximum load-bearing capacity and torsional rigidity. Key stress points—including the chassis mounting interface and suspension component attachment areas—are reinforced with triangular or rectangular ribs, which increase the bracket’s resistance to bending and deformation under heavy loads (up to 8000 N, depending on GX model). The bracket’s design also incorporates a curved contour that follows the GX’s chassis frame shape, minimizing gaps between components and distributing stress evenly across the entire bracket body. Additionally, the bracket includes dedicated positioning notches to ensure accurate installation alignment, preventing misalignment that could lead to premature suspension component wear

Bracket Body: Constructed from high-quality cold-rolled carbon steel (SAE 1015 or ST14) with a thickness of 5-8mm—selected for its excellent weldability, tensile strength (≥ 450 MPa), and yield strength (≥ 300 MPa). The material undergoes a phosphatization treatment before coating to enhance adhesion and rust resistance.

Surface Coating: Finished with a electrostatic powder coating (epoxy-polyester hybrid) with a thickness of 60-80μm. This coating provides superior resistance to corrosion (passing 500+ hours of salt spray testing), impact, and chemical damage (e.g., road salt, oil, and industrial contaminants), ensuring long-term durability in harsh operating environments.

Mounting Hardware Compatibility: The bracket’s bolt holes are designed to accommodate high-strength grade 8.8 or 10.9 bolts (common in Dongfeng GX suspension systems), with chamfered edges to prevent bolt thread damage during installation and ensure secure fastening

As a key structural component of the Dongfeng GX’s front suspension, this bracket fulfills three essential functions:

Component Securement: It serves as a stable mounting interface for critical front suspension parts—typically securing the right control arm, shock absorber lower mount, or stabilizer bar end link to the chassis frame. This ensures all suspension components remain in their designed positions during vehicle operation.

Load Distribution: It transfers vertical and lateral loads (from road impacts, cornering, and braking) between the suspension and chassis frame, preventing localized stress concentrations on individual components and extending the lifespan of the entire suspension system.

Alignment Maintenance: By maintaining fixed positioning of suspension components, the bracket helps preserve the GX’s front wheel alignment (toe, camber, and caster angles), ensuring stable handling, precise steering response, and uniform tire wear—critical for safe and efficient driving

This front suspension right end fixed bracket meets automotive industry quality standards, including China’s GB/T 13912 (Metallic coatings—Hot dip galvanized coatings on fabricated iron and steel articles) and ISO 1461 (Hot dip galvanizing of iron and steel articles), as well as IATF 16949 quality management system requirements. Each unit undergoes rigorous pre-shipment testing:

Dimensional Accuracy Testing: Using coordinate measuring machines (CMM) to verify all critical dimensions (hole spacing, thickness, contour) within OEM-specified tolerances.

Load-Bearing Testing: Subjecting the bracket to static and dynamic load tests (simulating 100,000+ km of driving) to ensure no deformation or cracking under maximum design loads.

Coating Performance Testing: Conducting cross-cut adhesion tests (grade ≥ 4B), impact tests (≥ 50 cm·kg), and salt spray tests to validate coating durability.

Weld Quality Testing (if applicable): For brackets with welded ribs, ultrasonic testing is performed to detect internal weld defects, ensuring structural integrity.

Backed by a 12-24 month manufacturer’s warranty, the bracket provides reliable performance for Dongfeng GX’s daily operation, including heavy-load transport and rough-road driving
