The 1327129280002 leaf spring assembly features a progressive multi-leaf design constructed from high-tensile spring steel, precision-tapered leaves, heat-treated for consistent elasticity, and fitted with heavy-duty bushings and rebound clips, providing exceptional load-carrying capacity, controlled deflection, and long-term fatigue resistance under the extreme weights, road impacts, and harsh operating conditions typical of heavy-duty trucking.
This 1327129280002 left front leaf spring assembly is a critical component of the vehicle’s front suspension system, effectively absorbing road shocks, maintaining proper ride height, and ensuring stable steering geometry. Its robust construction and high-quality materials guarantee dependable service, reducing driver fatigue and protecting the chassis from excessive stress.
OEM direct replacement • High-tensile spring steel • Progressive multi-leaf design • Heat-treated for durability
The 1327129280002 is a complete left front leaf spring assembly designed to provide precise suspension geometry and load distribution for SINOTRUK Howo trucks. It replaces the original equipment assembly, offering identical leaf count, thickness, curvature, and mounting dimensions, ensuring a perfect fit and restoration of original ride characteristics.
The assembly consists of multiple leaf springs stacked in a progressive arrangement, with the main leaf (top) featuring rolled eyes for bushing installation, and shorter graduated leaves beneath. The leaves are made from high-grade SUP9 or equivalent spring steel, heat-treated to achieve the optimal balance of strength and flexibility. Interleaf friction is minimized by precision-ground surfaces and optional anti-friction pads.
The assembly includes heavy-duty rubber or polyurethane bushings pressed into the main leaf eyes, providing noise and vibration isolation. Rebound clips and center bolts securely bind the leaves together, preventing lateral displacement and maintaining alignment. The entire assembly is coated with a durable anti-corrosion finish to withstand road salt and moisture.
This left front leaf spring assembly is a direct OEM replacement, ensuring that the vehicle’s front suspension operates with the correct spring rate and ride height, which is crucial for steering precision, tire wear, and braking performance.
The 1327129280002 left front leaf spring assembly is specifically designed for SINOTRUK Howo heavy-duty trucks, including popular models such as Howo A7, T7H, and other series that utilize this front spring configuration. It is a direct replacement for the OEM assembly, offering identical leaf count, spring rate, and mounting dimensions.
This leaf spring is suitable for a wide range of applications, including long-haul transport, regional distribution, construction, mining, and off-road operations, where robust suspension support is critical for load carrying, vehicle stability, and tire life. It is also compatible with many aftermarket suspension systems that use the same spring dimensions.
The 1327129280002 is typically used as a replacement for a broken, sagging, or fatigued leaf spring. Always verify the side (left front) and the vehicle’s axle weight rating before ordering to ensure correct fitment.
When replacing, inspect the spring hangers, shackles, and U-bolts for wear or damage, and replace any deteriorated components to ensure optimal suspension performance.
Installing the 1327129280002 left front leaf spring assembly requires adequate lifting equipment, proper tools, and mechanical expertise. Begin by safely lifting and supporting the front axle, then remove the wheel and tire assembly for access.
Support the axle with a jack stand, then remove the U-bolts securing the spring to the axle bracket. Disconnect the spring shackle bolts at both the front and rear hangers. Carefully lower the old spring assembly and remove it.
Position the new 1327129280002 spring assembly onto the axle bracket, ensuring the center bolt aligns with the locating hole. Install the U-bolts and torque them to the manufacturer’s specified value in a cross-pattern. Reconnect the shackle bolts, lubricate the bushings if needed, and torque to specification.
Reinstall the wheel, lower the vehicle, and bounce the suspension to settle the springs. Re-torque the U-bolts after a short test drive to account for initial settling. Check the ride height and wheel alignment if necessary.
Regular maintenance includes periodic inspection of the leaf springs for cracks, sagging, or broken leaves, checking the U-bolt torque, and lubricating the shackle pins and bushings. Replace the 1327129280002 if any significant deterioration is detected to maintain safe and stable suspension operation.
The 1327129280002 leaf spring assembly is manufactured in an ISO 9001-certified facility under rigorous quality control standards. Each spring is produced from premium steel and undergoes a complete heat treatment process, including quenching and tempering, to achieve the specified hardness and elasticity.
Every leaf is inspected for dimensional accuracy, surface defects, and curvature. The assembled spring is tested for load-deflection characteristics to ensure it meets OEM spring rate specifications. The bushings are verified for material hardness and press-fit retention. The final assembly is coated with a durable corrosion-resistant finish.
Our commitment to quality ensures that the 1327129280002 delivers reliable, consistent suspension performance, reducing the risk of sagging, breakage, and uneven tire wear. With a comprehensive warranty, this leaf spring assembly offers peace of mind for fleet operators and owner-operators alike.
