Single Leaf Spring with Clamp Assembly (2nd Leaf) OE 2912030-H02B1 for Dongfeng GX&KX | Genuine Truck Part

This is a genuine 2nd leaf spring with clamp assembly (OE:2912030-H02B1) specially designed for Dongfeng GX&KX heavy-duty trucks, serving as a critical component of the leaf spring suspension system to absorb road shocks and support heavy axle loads. It features 100% direct fit with original leaf spring stack and axle interfaces, requiring no modification during installation. Made of high-grade 60Si2Mn spring steel with precision rolling and advanced heat treatment, this leaf spring is certified by Dongfeng original factory standards. Third-party durability tests confirm it features exceptional elasticity, fatigue resistance and load capacity, operating stably across -40℃ to 85℃. With its integrated clamp design, it effectively maintains leaf alignment, prevents inter-leaf friction and ensures reliable suspension performance for heavy-duty truck operation.

PRODUCT DESCRIPTION

01

High-Strength Spring Steel & Integrated Clamp Design

This 2nd leaf spring assembly OE 2912030-H02B1 is manufactured strictly to Dongfeng GX&KX original design specifications, forged from high-grade 60Si2Mn spring steel that delivers exceptional elasticity and fatigue resistance—critical for absorbing heavy road shocks and maintaining suspension stability. The product features an integrated metal clamp that securely holds the leaf spring in position within the stack, preventing lateral misalignment and reducing inter-leaf friction. The precision-rolled profile and optimized curvature ensure consistent load distribution and long-term elasticity under repeated loading. It adopts a 1:1 original dimensional design, with precise eyelet and clamp tolerances that perfectly match the truck’s leaf spring stack and axle, ensuring a tight, stable fit and uniform load transfer. This robust design combines elasticity and alignment control, making it the ideal OEM replacement for Dongfeng GX&KX heavy-duty trucks.

02

Leaf Breakage, Misalignment & Suspension Failure

Fully compatible with all applicable Dongfeng GX&KX truck models, this 2nd leaf spring assembly can be quickly verified via OE 2912030-H02B1 to ensure accurate matching. It solves multiple common failures caused by low-quality aftermarket leaf springs: inferior spring steel leading to brittle fracture and fatigue breakage, missing or weak clamps causing lateral misalignment and inter-leaf wear, poor heat treatment leading to loss of elasticity and sagging, and mismatched dimensions causing uneven load distribution and suspension instability. A faulty leaf spring will cause rough rides, wheel wobble and even rear axle breakdowns—posing a serious threat to driving safety and fleet operation. By using this genuine high-strength leaf with clamp, users can eliminate breakage, misalignment and suspension failure problems, ensuring reliable rear axle performance.

03

OEM Certification & Strict Fatigue Testing

As a key component for heavy-duty truck suspension systems, this 2nd leaf spring meets Q/DFL 6020-2021 Dongfeng automotive parts quality standards and has passed authoritative third-party tests for elasticity, fatigue resistance and load capacity. Test data shows the leaf spring withstands 100,000 cycles of repeated loading without fatigue fracture, maintains stable elasticity after 500 hours of salt spray testing, and supports a dynamic load rating of ≥120kN. Each leaf undergoes 100% dimensional inspection, curvature verification and fatigue testing before leaving the factory, ensuring complete consistency with original factory parts in performance, durability and fit. It performs reliably in all operating conditions, with strong resistance to fatigue, corrosion and temperature fluctuations. Backed by complete factory traceability and quality certification, it provides users with long-term, trustworthy suspension performance.
