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.
