The DONGFENG Front Leaf Spring Assembly, part number 2912010-H02B1, is a complete suspension unit designed for the front axle of heavy-duty trucks. This assembly consists of multiple steel leaves of varying lengths, clamped together to form a flexible yet sturdy spring. Its primary function is to support the vehicle’s weight, absorb road irregularities, and maintain axle alignment, ensuring stability and control. The 2912010-H02B1 is engineered to meet the exact specifications of DONGFENG trucks, providing a perfect fit and restoring original suspension geometry.
In commercial operations, the front leaf spring is critical for safety and load management. A worn or broken spring can lead to uneven tire wear, poor handling, and even loss of vehicle control. By replacing it with the genuine 2912010-H02B1 assembly, operators ensure their truck maintains factory performance, safety margins, and compliance with weight distribution regulations. This component is particularly vital for trucks carrying heavy loads or operating on rough terrain.
The 2912010-H02B1 leaf spring assembly is manufactured from high-carbon steel or alloy steel, known for its excellent strength and fatigue resistance. Each leaf is precision-rolled to a specific curvature and heat-treated to achieve optimal hardness and flexibility. The leaves are then assembled with a center bolt and clamped with robust U-bolts and rebound clips to ensure they work in unison under load.
To reduce friction and noise between leaves, anti-friction pads or coatings are often applied. The main leaf (master leaf) features rolled eyes at both ends, which accommodate bushings for secure attachment to the vehicle frame and shackles. The design of the 2912010-H02B1 ensures progressive spring action—the spring rate increases with load, providing a balance between ride comfort when empty and stability when fully laden.

The specifications for the 2912010-H02B1 demonstrate its heavy-duty construction and exact engineering for DONGFENG trucks. The use of heat-treated steel and proper hardware ensures longevity and reliable performance under maximum load conditions.
Replacing a front leaf spring assembly is a significant task that should be performed by experienced technicians using proper equipment. The vehicle must be securely lifted and supported, with the front axle suspended. After safely removing the wheel, the old assembly is detached by loosening the U-bolts, shackle bolts, and front hanger bolts. Care must be taken as the spring is under tension.
The new 2912010-H02B1 assembly is then positioned, ensuring the center bolt aligns with the axle seat. All mounting points (front hanger, shackle, and U-bolts) are tightened to the manufacturer’s specified torque sequence and values. It is crucial to replace all worn bushings, bolts, and shackles during installation. After installation, the vehicle should be lowered gradually and a wheel alignment performed to ensure proper tracking and tire wear.
Superior Load-Bearing Capacity: The 2912010-H02B1 is engineered to support substantial front-axle loads, maintaining ride height and stability even when the truck is fully loaded. This prevents bottoming out and ensures safe handling.
Enhanced Durability & Fatigue Resistance: The heat-treated steel leaves are designed to withstand millions of flex cycles without failure. This results in a long service life, reducing downtime and replacement frequency in demanding applications.
Improved Ride Quality & Stability: The progressive spring rate of the 2912010-H02B1 provides a smoother ride when unloaded and firm support when loaded. This balance improves driver comfort and vehicle control on various road surfaces.
Maintained Vehicle Safety & Alignment: A properly functioning leaf spring keeps the axle in correct alignment, promoting even tire wear and consistent braking performance. This is critical for overall road safety.
The 2912010-H02B1 Front Leaf Spring Assembly is designed for specific DONGFENG heavy-duty truck models, commonly used in construction, logging, mining, and long-haul freight transport. These trucks require a suspension system capable of handling constant heavy loads and rough terrain. The 2912010-H02B1 is a direct replacement for the original front springs on compatible models.
It is essential to verify the vehicle’s model, production year, and axle configuration before ordering the 2912010-H02B1. Using the correct spring ensures the designed load capacity, ride height, and handling characteristics are preserved. Fleet managers operating in severe conditions should keep this part in inventory to minimize vehicle downtime.
Each 2912010-H02B1 leaf spring assembly undergoes rigorous quality control tests. These include fatigue testing, where the spring is subjected to millions of load cycles to simulate years of service. Static load testing verifies the spring rate and deflection under specific weights. Material tests ensure the steel meets hardness and tensile strength specifications.
Additionally, the assembly is checked for dimensional accuracy, including eye-to-eye distance, center bolt alignment, and leaf curvature. The painting or coating process is inspected for adhesion and corrosion resistance. These comprehensive tests guarantee that the 2912010-H02B1 delivered will perform reliably and safely in the field.
Regular inspection of the front leaf spring assembly, including the 2912010-H02B1, is vital for safety. Look for signs of leaf fracture (often near the center bolt or eye), sagging, or loose U-bolts. Listen for squeaking or clunking noises, which may indicate worn bushings or broken clips.
Keep the springs clean and check for corrosion, especially in areas using road salt. If a leaf is broken or the assembly is sagging significantly, replace the entire 2912010-H02B1 assembly rather than individual leaves to ensure balanced performance. Always tighten U-bolts to the correct torque and re-torque them after the first few hundred kilometers of use, as they may settle.
While aftermarket leaf springs are available, the genuine 2912010-H02B1 offers significant advantages. OEM parts are engineered to the exact specifications of the vehicle, ensuring correct spring rate, load capacity, and dimensions. The material quality and heat-treatment processes in genuine parts like the 2912010-H02B1 are controlled to achieve optimal strength and fatigue life.
Aftermarket springs may use inferior steel or improper heat treatment, leading to premature sagging or breakage. They might also have dimensional variances that affect ride height and alignment. Investing in the genuine 2912010-H02B1 ensures safety, reliability, and a perfect fit, protecting your vehicle and cargo investment.
The DONGFENG Front Leaf Spring Assembly, part number 2912010-H02B1, is a cornerstone of your truck’s suspension system. Its robust design, precise engineering, and proven durability make it an indispensable component for maintaining load capacity, ride comfort, and safety in demanding commercial operations.
Choosing the genuine 2912010-H02B1 for replacement or repair guarantees performance that matches the original equipment, ensuring your DONGFENG truck continues to operate at its best. Trust in this OEM part to provide the reliable foundation your heavy-duty truck requires.
