The Mitsubishi Fuso leaf spring OEM MK306250 is a vital rear/front suspension component used widely in light-to-medium commercial vehicles, delivery trucks, and cargo haulers. Forged from high-grade alloy spring steel, this multi-leaf assembly efficiently absorbs road impact forces, minimizes chassis vibration, and maintains consistent ride height even when carrying maximum rated payloads.

Whether operating in urban delivery networks, regional logistics, or rural transport routes, our Mitsubishi Fuso leaf spring ensures long service life and reduced vehicle maintenance costs. We manufacture exact OEM-fit replacement leaf spring assemblies as well as customized suspension components tailored to customer drawings, physical samples, or custom technical specifications.

Technical Inspection & Quality Control

Quality is tightly monitored throughout our manufacturing process to ensure consistent reliability and load performance:

• Dimensional Accuracy Check: Comprehensive gauge testing for overall spring length, arch height, center bolt positioning, and eye inner diameters.

• Load & Camber Verification: Tested on hydraulic load machines to ensure compliance with load-deflection standards.

• Metallographic & Hardness Testing: Metallurgical analysis ensures proper heat treatment structure and uniform hardness throughout each leaf.

• Flaw Detection (NDT): Non-destructive magnetic particle testing is performed to rule out internal material defects or surface cracks.

Manufacturing Process

Our production facility uses modern leaf spring manufacturing lines:

1. Material Selection: Certified high-grade alloy spring steel bars undergo rigorous chemical and mechanical property checks.

2. Shearing & Heating: Precision shearing followed by controlled heating for eye forming and tapering.

3. Heat Treatment & Shot Peening: Computer-controlled quenching and tempering maximize toughness, while shot peening enhances fatigue resistance.

4. Coating & Assembly: Corrosion-resistant paint is applied before leaves are assembled with high-tensile center bolts and clips.

5. Final QC & Packaging: 100% visual, dimensional, and load inspection prior to export packing.

Packaging & Export Shipping

To ensure your Mitsubishi Fuso leaf spring shipment arrives undamaged during international sea freight, we follow strict export packaging protocols:

• Anti-Rust Protection: Treated with anti-corrosion oils and wrapped in durable waterproof plastic film.

• Steel Banding: Strapped tightly with high-tensile steel bands to prevent displacement during transport.

• Container Optimization: Tailored container loading plans maximize payload space in 20ft and 40ft containers.
